Description

La présente invention concerne un chariot automoteur à bras télescopique et rehausse, utilisable pour des opérations ou travaux de manutention, de levage, de terrassement, etc, notamment sur des chantiers de bâtiments ou de génie civil.The present invention relates to a self-propelled carriage with arms Telescopic and raisable, usable for operations or work of handling, lifting, earth moving, etc., especially on building or civil engineering sites.

On connaít déjà, par le brevet français N° 2 457 240 (MONTGON), un véhicule automoteur muni de stabilisateurs, d'une cabine de conduite fixe et d'une tourelle montée tournante sur le châssis du véhicule et supportant un bras télescopique, par l'intermédiaire d'une rallonge de surélévation ou " rehausse ".We already know, by French Patent No. 2,457,240 (MONTGON), a self-propelled vehicle equipped with stabilizers, a cabin fixed and a revolving turret mounted on the chassis of the vehicle and supporting a telescopic arm, via a extension extension or "raises".

La rallonge de surélévation ou rehausse de cet engin est articulable par une extrémité à l'avant de la tourelle, autour d'un axe horizontal, sur un angle compris entre 0° et 100° environ, à partir de sa position repliée à l'horizontale. L'autre extrémité de la rehausse est articulable, autour d'un axe horizontal, au pied du bras télescopique. Un crochet de levage, motorisé par un treuil, est prévu à l'extrémité avant du bras télescopique. Les actionneurs, destinés au déploiement de cette structure, sont de simples vérins sans embiellage, comprenant un vérin monté entre la tourelle et la rehausse, et un autre vérin monté entre la rehausse et le pied du bras télescopique.The raising or raising extension of this machine is articulable by one end at the front of the turret, around an axis horizontally, at an angle between 0 ° and 100 ° approximately, from its position folded horizontally. The other end of the riser is articulable, around a horizontal axis, at the foot of the telescopic arm. A lifting hook, motorized by a winch, is provided at the front end of the telescopic arm. The actuators, intended for the deployment of this structure, are simple cylinders without linkage, comprising a jack mounted between the turret and the riser, and another cylinder mounted between the raises and the foot of the telescopic arm.

Un tel engin est bien adapté à des travaux de manutention en hauteur, par exemple des tâches de manutention de charges pour la construction d'un bâtiment, effectuées en relevant plus ou moins la rehausse, le bras télescopique occupant une position horizontale ou inclinée. Toutefois, la réalisation du brevet français N° 2 457 240 possède les inconvénients et insuffisances suivants :

  • L'engin est limité, dans son utilisation, à la manutention ou au levage de charges suspendues à un crochet ; il n'est pas conçu pour recevoir des équipements de travail tels que godet, fourche de chargement ou nacelle, qui permettraient des utilisations plus diversifiées.
  • Comme indiqué plus haut, l'angle maximal d'articulation de la rehausse est de l'ordre de 100°. De plus, l'articulation du bras télescopique relativement à la rehausse est, en pratique, limitée aussi à un angle de cet ordre, compte tenu des moyens de commande prévus qui sont des vérins sans embiellage. Il en résulte que la zone de travail de l'engin est limitée ; en particulier, l'engin n'est pas conçu pour travailler sur le secteur arrière supérieur de manutention.
  • Toujours en raison des limitations angulaires des mouvements de la rehausse et du bras télescopique, la portée maximale du bras est limitée à la position dépliée sensiblement verticale de la rehausse.
  • Il n'est pas prévu d'appui de la rehausse en position repliée, de sorte que l'engin ne peut être utilisé, avec sa rehausse repliée, à la manière d'une grue mobile à flèche télescopique avec des caractéristiques de fonctionnement identiques à celles d'une telle grue.
  • La cabine étant fixe et située en position basse, la vision de l'opérateur posté dans cette cabine est limitée et les opérations de manutention nécessitent la présence d'un opérateur auxiliaire, servant à signaler les obstacles, en particulier un obstacle présent au niveau du poste de conduite.
Such a machine is well suited for handling work at height, for example load handling tasks for the construction of a building, made by raising more or less the extension, the telescopic arm occupying a horizontal or inclined position. However, the realization of French Patent No. 2,457,240 has the following disadvantages and shortcomings:
  • The machine is limited in its use in handling or lifting loads suspended from a hook; it is not designed to accommodate work equipment such as bucket, loading fork or carrycot, which would allow more diverse uses.
  • As indicated above, the maximum articulation angle of the riser is of the order of 100 °. In addition, the articulation of the telescopic arm relative to the extension is, in practice, also limited to an angle of this order, given the control means provided which are cylinders without linkage. As a result, the work area of the machine is limited; in particular, the machine is not designed to work on the upper rear sector handling.
  • Still due to the angular limitations of the movements of the riser and the telescopic arm, the maximum arm span is limited to the substantially vertical unfolded position of the riser.
  • It is not planned to support the riser in the folded position, so that the machine can not be used, with its folded extension, in the manner of a mobile crane telescopic boom with operating characteristics identical to those of such a crane.
  • The cabin being fixed and located in the low position, the vision of the operator posted in this cabin is limited and the handling operations require the presence of an auxiliary operator, used to signal obstacles, in particular an obstacle present at the level of the operator. cockpit.

Le brevet français N° 2 444 639 (POTAIN) décrit un autre exemple d'engin automoteur à bras télescopique avec fourreau d'articulation, qui d'une façon générale conserve les mêmes inconvénients : limitation des angles d'articulation du fourreau et du bras, à des valeurs d'environ 90°, donc du domaine de travail (limité à un secteur de 90°) ; limitation de l'utilisation à la manutention de charges suspendues à un crochet ; visibilité insuffisante pour l'opérateur.French Patent No. 2,444,639 (POTAIN) describes another example of a self-propelled machine with telescopic arm with scabbard articulation, which in a general way retains the same disadvantages: limitation of the angles of articulation of the sheath and the arm, at values of about 90 °, so the working range (limited to one 90 ° sector); limitation of use in handling loads hanging on a hook; insufficient visibility for the operator.

Encore un autre engin automoteur analogue est décrit dans la demande de brevet français N° 2 761 972 (MODULES ASSOCIES). Le bras télescopique est articulé sur la rehausse selon un angle théorique de 180°, mais la rehausse est articulée sur le châssis selon un angle de l'ordre de 90°, entre une position repliée vers l'arrière et une position relevée, de sorte que là aussi, la zone de travail reste limitée.Yet another similar self-propelled machine is described in the French Patent Application No. 2,761,972 (Associated Modules). The telescopic arm is articulated on the riser according to a theoretical angle of 180 °, but the riser is hinged to the frame at an angle of the order of 90 °, between a folded position to the rear and a position noted, so that there too, the work area remains limited.

La présente invention vise à éviter tous les inconvénients précédemment exposés, en fournissant un engin du genre considéré, mais d'une structure et d'une cinématique perfectionnées, de manière notamment à optimiser le volume de travail, tout en permettant des utilisations très diversifiées, la visibilité étant elle aussi grandement améliorée pour l'opérateur.The present invention aims at avoiding all the disadvantages previously exposed, providing a gear of the kind considered, but sophisticated structure and kinematics, so in particular to optimize the volume of work, while allowing very diverse uses, visibility being also greatly improved for the operator.

A cet effet, l'invention a pour objet un chariot automoteur à bras télescopique et rehausse, la rehausse étant articulable par une extrémité, autour d'un axe horizontal, sur un châssis porteur et étant articulable, par son extrémité opposée, autour d'un autre axe horizontal, au pied du bras télescopique dont l'extrémité avant reçoit un équipement de travail, des moyens motorisés étant prévus pour commander l'articulation de la rehausse relativement au châssis et l'articulation du bras télescopique relativement à la rehausse, et un poste de conduite étant prévu,
   le châssis comportant des moyens d'appui pour la rehausse repliée vers l'arrière,
   le pied du bras télescopique étant articulable à la rehausse sur un angle de l'ordre de 180°, entre une position repliée contre la rehausse et une position déployée dans l'alignement de la rehausse,
   les moyens motorisés de commande de l'articulation du bras télescopique étant conçus pour commander effectivement l'articulation de ce bras sur un angle de l'ordre de 180°, relativement à la rehausse,
   l'extrémité avant dudit bras télescopique étant pourvue d'un dispositif de liaison apte à recevoir de façon interchangeable divers équipements de travail, ce chariot automoteur étant caractérisé en ce que :

  • la rehausse est articulable sur le châssis sur un angle de l'ordre de 180°, entre une position repliée vers l'arrière et une position déployée vers l'avant,
  • les moyens motorisés de commande de l'articulation de la rehausse sont conçus pour commander effectivement l'articulation de cette rehausse sur un angle de l'ordre de 180°, relativement au châssis,
For this purpose, the object of the invention is a self-propelled wagon with telescopic arm and raises, the riser being hinged at one end, about a horizontal axis, on a support frame and being articulable, at its opposite end, around another horizontal axis, at the foot of the telescopic arm whose front end receives a work equipment, motorized means being provided to control the articulation of the riser relative to the frame and the articulation of the telescopic arm relative to the riser, and a driving position being provided,
the chassis comprising support means for the retracted rearward extension,
the foot of the telescopic arm being articulable to the riser at an angle of the order of 180 °, between a folded position against the riser and a deployed position in the alignment of the riser,
the motorized means for controlling the articulation of the telescopic arm being designed to effectively control the articulation of this arm at an angle of the order of 180 °, relative to the extension,
the front end of said telescopic arm being provided with a connecting device adapted to interchangeably receive various work equipment, said self-propelled carriage being characterized in that:
  • the riser is articulable on the frame at an angle of the order of 180 °, between a folded position towards the rear and a deployed position forward,
  • the motorized means for controlling the articulation of the riser are designed to effectively control the articulation of this riser at an angle of the order of 180 ° relative to the chassis,

Ainsi, l'invention fournit un engin automoteur à cinématique particulière, qui combine :

  • un débattement angulaire de la rehausse par rapport au châssis de l'ordre de 180°, entre une position repliée vers l'arrière, et une position déployée vers l'avant, positions sensiblement horizontales ;
  • un débattement angulaire du bras télescopique par rapport à la rehausse qui est aussi de l'ordre de 180°, entre une position de ce bras repliée contre la rehausse et une position du même bras dépliée, amenant ce bras dans l'alignement de la rehausse.
Thus, the invention provides a self-propelled machine with particular kinematics, which combines:
  • an angular displacement of the riser relative to the frame of the order of 180 °, between a folded position towards the rear, and a deployed position forward, substantially horizontal positions;
  • an angular displacement of the telescopic arm relative to the enhancement which is also of the order of 180 °, between a position of this arm folded against the raising and a position of the same unfolded arm, bringing this arm in alignment with the riser .

Des angles d'articulation de l'ordre de 180° peuvent être effectivement obtenus en prévoyant, selon un mode de réalisation préféré de l'invention, que les moyens motorisés de commande de l'articulation de la rehausse, relativement au châssis, sur un angle de l'ordre de 180° sont constitués par au moins un dispositif à vérin et embiellage, et que les moyens motorisés de commande de l'articulation du bras télescopique, relativement à la rehausse, sur un angle de l'ordre de 180° sont, eux aussi, constitués par au moins un dispositif à vérin et embiellage.Articulation angles of the order of 180 ° can be actually obtained by providing, according to a preferred embodiment of the invention, that the motorized control means of the articulation of the raising, relative to the frame, on an angle of the order of 180 ° are constituted by at least one jack and linkage device, and that the motorized means for controlling the articulation of the telescopic arm, relative to the extension, on an angle of the order of 180 ° are, them also constituted by at least one device with jack and linkage.

Grâce à la combinaison de ces débattements angulaires, le chariot automoteur peut couvrir une zone de travail importante, dont l'aire comprend dans le plan vertical :

  • un secteur supérieur arrière, dont l'enveloppe maximale est déterminée par les positions " rehausse sensiblement horizontale repliée vers l'arrière, bras télescopé aligné avec la rehausse " et " rehausse sensiblement verticale, bras télescopé aligné avec la rehausse " (ce secteur n'étant pas couvert dans l'état actuel de la technique) ;
  • un secteur supérieur avant, dont l'enveloppe maximale est déterminée par les positions " rehausse sensiblement verticale, bras télescopé aligné avec la rehausse " et " rehausse sensiblement horizontale, déployée vers l'avant, bras télescopé aligné avec la rehausse " ; cette couverture étant supérieure à celle de la technique antérieure, compte tenu du fait que la réhausse occupe une position déployée sensiblement horizontale ;
  • un secteur inférieur avant, dont l'enveloppe maximale est déterminée par les positions " rehausse sensiblement horizontale, déployée vers l'avant, bras télescopé aligné avec la rehausse " et " rehausse sensiblement horizontale, déployée vers l'avant, bras télescopé sensiblement vertical, dirigé vers le bras " ; cette couverture est supérieure à celle de la technique existante, compte tenu du fait que la rehausse occupe une position déployée sensiblement horizontale ;
  • un secteur inférieur arrière, dont l'enveloppe est déterminée par les positions " rehausse sensiblement horizontale, déployée vers l'avant, bras télescopé sensiblement vertical, dirigé vers le bas " et " rehausse sensiblement horizontale, déployée vers l'avant, bras télescopé en position inclinée, sous la rehausse " (ce dernier secteur n'étant pas couvert dans l'état de la technique).
Thanks to the combination of these angular deflections, the self-propelled carriage can cover a large working area, whose area includes in the vertical plane:
  • a rear upper sector, whose maximum envelope is determined by the positions "raises substantially horizontally folded backwards, telescoped arm aligned with the riser" and "raises substantially vertical, telescoped arm aligned with the riser" (this sector n ' being not covered in the current state of the art);
  • an upper front sector, the maximum envelope of which is determined by the positions "raises substantially vertical, telescoped arm aligned with the extension" and "raises substantially horizontal, extended forward, telescoped arm aligned with the extension"; this coverage being greater than that of the prior art, given that the raiser occupies a substantially horizontal deployed position;
  • a lower front sector whose maximum envelope is determined by the positions "raises substantially horizontal, deployed forward, telescoped arm aligned with the raising" and "raises substantially horizontal, extended forward, telescoped arm substantially vertical, directed to the arm "; this coverage is greater than that of the existing technique, given that the riser occupies a substantially horizontal deployed position;
  • a lower rear sector, whose envelope is determined by the positions "raises substantially horizontal, extended forward, substantially vertical telescoped arm, directed downwards" and "raises substantially horizontal, extended forward, arm telescoped in inclined position, under the riser "(the latter sector is not covered in the state of the art).

Les possibilités d'inclinaison variable de la rehausse par rapport au châssis, combinées à l'inclinaison variable du bras par rapport à la rehausse et au télescopage du bras, permettent de couvrir l'aire totale de chacun des quatre secteurs précédemment définis, donc de desservir tout point de la zone de travail précédemment définie.The possibilities of variable inclination of the extension relative to to the chassis, combined with the varying inclination of the arm relative to the raising and telescoping the arm, allow to cover the total area of each of the four previously defined sectors, so to serve all point of the previously defined work area.

De plus, dans le cas où la rehausse est articulable, par sa première extrémité, sur l'avant d'un châssis tournant ou " tourelle " orientable autour d'un axe vertical par rapport à un châssis de base du chariot automoteur, la structure et la cinématique de l'engin permettent de couvrir le volume total engendré par la rotation de l'aire de travail précédemment définie, autour d'un axe vertical.Moreover, in the case where the enhancement is articulable, by its first end, on the front of a rotating chassis or "turret" orientable about a vertical axis relative to a base frame of the self-propelled carriage, the structure and the kinematics of the machine make it possible cover the total volume generated by the rotation of the work area previously defined, around a vertical axis.

Par ailleurs, l'appui mécanique de la rehausse, dans sa position repliée vers l'arrière, permet le travail du bras télescopique seul, à caractéristiques identiques à celles d'un chariot automoteur classique à bras télescopique, dépourvu de rehausse. Ainsi, la position repliée de la rehausse n'est pas une simple position de transport, mais aussi une véritable position de travail.Moreover, the mechanical support of the riser, in its position folded backwards, allows the work of the telescopic arm alone, to characteristics identical to those of a conventional self-propelled telescopic arm, without extension. Thus, the folded position of the enhances is not just a transport position, but also a real working position.

L'appui de la rehausse sur le châssis peut être un simple appui guidé, en général suffisant ; dans un mode de réalisation, les moyens d'appui comprennent, sur le châssis, des éléments verticaux en forme de " U " avec guidages latéraux, qui coopèrent avec une traverse horizontale fixée sur la face arrière de la rehausse, dans la région de la deuxième extrémité de cette rehausse, sur laquelle est articulé le bras télescopique. En variante, il peut aussi s'agir d'un appui bloqué, empêchant le soulèvement de la rehausse, par exemple au moyen de crochets rabattus et verrouillés sur ladite traverse.The support of the riser on the chassis can be a simple support guided, usually sufficient; in one embodiment, the means of support comprise, on the chassis, vertical elements in the form of "U" with lateral guides, which cooperate with a horizontal crossbar attached to the back side of the riser, in the area of the second end of this extension, on which is articulated the telescopic arm. Alternatively, it may also be a stuck support, preventing the raising of the extension, for example by means of hooks folded down and locked on said crossbeam.

Selon une autre caractéristique avantageuse, le poste de conduite du chariot automoteur est conformé en cabine de conduite, montée mobile en hauteur sur le châssis par l'intermédiaire d'une structure en parallélogramme déformable, motorisée par au moins un vérin, permettant de déplacer la cabine entre une position basse et une position haute. Avantageusement, la position haute de la cabine est située sensiblement au niveau de l'extrémité de la rehausse à laquelle est articulable le bras télescopique, lorsque la rehausse occupe sa position sensiblement verticale. L'opérateur de l'engin peut ainsi bénéficier, à tout instant, d'un champ de vision optimal sur la charge à manutentionner, ou sur l'équipement de travail. Selon une disposition complémentaire, la commande motorisée de position en hauteur de la cabine est couplée à la commande de relevage de la rehausse, pour ajuster en permanence et automatiquement le champ de vision de l'opérateur.According to another advantageous characteristic, the position of the self-propelled carriage is shaped in the driver's cab, mounted vertically on the chassis via a structure deformable parallelogram, motorized by at least one jack, to move the car between a low position and a position high. Advantageously, the upper position of the cabin is located substantially at the end of the enhancement to which is articulable the telescopic arm, when the raiser occupies its position substantially vertical. The operator of the machine can benefit, at any moment, an optimal field of view on the load to be handled, or on work equipment. According to a complementary provision, the motorized control of position in height of the cabin is coupled with the raises the lift, to continuously adjust and automatically the field of view of the operator.

Par ailleurs, le dispositif de liaison, prévu à l'extrémité avant ou " tête " du bras télescopique, peut recevoir divers équipements de travail, tels que notamment crochet fixe ou treuil de levage, fourche, godet, nacelle, etc., lesquels peuvent être amenés en tout point de la zone de travail précédemment définie.Moreover, the connecting device, provided at the front end or "head" of the telescopic arm, can receive various work equipment, such as in particular fixed hook or lifting winch, fork, bucket, nacelle, etc., which may be brought anywhere in the previously defined work.

Ainsi, dans l'ensemble, le chariot automoteur objet de l'invention convient à des utilisations multiples et diversifiées, effectuées dans une zone de travail importante, incluant les secteurs arrière supérieur et inférieurs, qui sont pertinents pour des applications particulières. Dans toutes ces utilisations, on bénéficie d'une augmentation sensible de la portée de l'engin, grâce au débattement important de la rehausse et aux possibilités d'utilisation avec alignement de la rehausse et du bras télescopique, ceci n'excluant pas la possibilité de travailler avec le bras télescopique seul, la rehausse restant repliée. La mobilité verticale de la cabine procure, dans tous types d'utilisations et toutes positions de la rehausse, une excellente visibilité. Enfin, les fonctions de repliage et de télescopage permettent de placer l'engin dans une configuration de transport peu encombrante, la cabine de conduite étant alors abaissée, pour le déplacement sur route du chariot automoteur.Thus, overall, the self propelled trolley the invention is suitable for multiple and diverse uses, carried out in a large work area, including the upper rear areas and lower, which are relevant for particular applications. In all these uses, we benefit from a significant increase in the reach of the machine, thanks to the high clearance of the extension and possibilities of use with alignment of the extension and the arm telescopic, this does not exclude the possibility of working with the arm telescopic alone, the riser remaining folded. The vertical mobility of the cabin provides, in all types of uses and all positions of the enhances, excellent visibility. Finally, the functions of folding and Telescoping allows to place the machine in a configuration of space-saving transport, the cab is then lowered, for the road travel of the self-propelled wagon.

    • Le chariot automoteur, représenté notamment aux figures 1 et 2, possède un châssis de base 1 monté sur des roues à pneumatiques 2, et pourvu de stabilisateurs 3. Sur le châssis de base 1 est monté un châssis tournant 4, orientable autour d'un axe vertical 5 qui, dans l'exemple illustré, passe par le centre du châssis de base 1. Le châssis tournant 4 porte une structure articulée composée d'une rehausse 6 et d'un bras télescopique 7. Sur le châssis tournant 4 est aussi montée une cabine de conduite 8.The self-propelled carriage, represented in particular in FIGS. 2, has a base frame 1 mounted on tire wheels 2, and provided with stabilizers 3. On the base frame 1 is mounted a rotating frame 4, orientable about a vertical axis 5 which, in the example shown, goes through the center of the base chassis 1. The chassis rotating 4 carries an articulated structure composed of a riser 6 and of a telescopic arm 7. On the rotating chassis 4 is also mounted a driving cabin 8.

    La rehausse 6, constituée d'une poutre en caisson, possède une première extrémité qui est articulable, autour d'un axe horizontal 9, à l'avant du châssis tournant 4. La rehausse 6 est aussi reliée au châssis tournant 4 par un ensemble motorisé, composé d'un vérin 10 et d'un embiellage 11. L'articulation autour de l'axe 9, et l'ensemble motorisé 10-11, permettent une rotation de la rehausse 6 sur un angle de l'ordre de 180°, entre deux positions extrêmes, l'une sensiblement horizontale dans laquelle la rehausse 6 est repliée vers l'arrière, et l'autre aussi sensiblement horizontale, mais dans laquelle la rehausse 6 est déployée vers l'avant.The riser 6, consisting of a box beam, has a first end which is articulable, around a horizontal axis 9, to the front of the rotating frame 4. The riser 6 is also connected to the frame rotating 4 by a motorized assembly, consisting of a cylinder 10 and a linkage 11. The articulation about the axis 9, and the motorized assembly 10-11, allow a rotation of the riser 6 on an angle of the order of 180 °, between two extreme positions, one substantially horizontal in which the raises 6 is folded backwards, and the other also substantially horizontal, but in which the riser 6 is deployed forward.

    Le bras télescopique 7 se compose de plusieurs éléments successifs, soit par exemple un premier élément 12 dit pied, un élément intermédiaire 13 et un élément terminal 14, lequel est pourvu, à son extrémité avant, d'une tête 15. Le pied 12 du bras télescopique 7 est articulable, autour d'un axe horizontal 16, à la deuxième extrémité de la rehausse 6. Ce pied 12 est aussi relié à la rehausse 6 par un ensemble motorisé, composé d'un vérin 17 et d'un embiellage 18. L'articulation autour de l'axe 16, et l'ensemble motorisé 17-18, permettent une rotation du bras télescopique 7, relativement à la rehausse 6, sur un angle de l'ordre de 180°, entre deux positions extrêmes ; dans l'une de ses positions extrêmes, le bras télescopique 7 est replié contre la rehausse 6, tandis que dans son autre position extrême, le bras télescopique 7 est déployé dans l'alignement de la rehausse 6.The telescopic arm 7 is composed of several elements successive, for example a first element 12 said foot, an element intermediate 13 and a terminal element 14, which is provided, at its front end, a head 15. The foot 12 of the telescopic arm 7 is articulable, about a horizontal axis 16, at the second end of the raises 6. This foot 12 is also connected to the riser 6 by a set motorized, consisting of a cylinder 17 and a linkage 18. The articulation around the axis 16, and the motorized assembly 17-18, allow a rotation of the telescopic arm 7, relative to the extension 6, on an angle of the order of 180 °, between two extreme positions; in one of his extreme positions, the telescopic arm 7 is folded against the riser 6, while in its other extreme position, the telescopic arm 7 is deployed in the alignment of the riser 6.

    Le châssis tournant 4 comporte, à l'arrière, une structure d'appui 19 pour la rehausse 6, structure qui est bien visible sur la figure 2. La structure d'appui 19 comprend des éléments verticaux 20 en forme de " U ", qui coopèrent avec une traverse horizontale 21 fixée sur la face arrière 22 de la rehausse 6, à proximité de la deuxième extrémité de cette rehausse 6, donc de l'axe d'articulation 16 du bras télescopique 7.The rotating frame 4 comprises, at the rear, a structure support 19 for the riser 6, which structure is clearly visible in FIG. The support structure 19 comprises vertical elements 20 in the form of "U", which cooperate with a horizontal cross member 21 fixed on the face rear 22 of the riser 6, near the second end of this raises 6, therefore the hinge axis 16 of the telescopic arm 7.

    La cabine de conduite 8 est montée mobile en hauteur sur le châssis tournant 4, par l'intermédiaire d'une structure en parallélogramme déformable qui comprend des bielles 23 articulées sur les éléments verticaux 20 de la structure d'appui 19. Cette structure en parallélogramme déformable est motorisée par un vérin, non représenté. La cabine 8 peut ainsi être déplacée entre une position basse (figures 1 et 4) et une position haute (figure 5), avec possibilité d'occuper des positions intermédiaires (figures 6 et 7). Le plan de déplacement vertical de la cabine 8 se situe sur le côté du plan de déplacement de la rehausse 6 et du bras télescopique 7.The driving cabin 8 is mounted mobile in height on the rotating frame 4, via a parallelogram structure deformable which includes connecting rods 23 articulated on the elements 20 of the support structure 19. This structure in deformable parallelogram is motorized by a jack, not shown. The cabin 8 can thus be moved between a low position (FIGS. 1 and 4) and a high position (Figure 5), with the possibility of occupying positions intermediates (Figures 6 and 7). The vertical displacement plan of the cabin 8 is located on the side of the plane of displacement of the riser 6 and telescopic arm 7.

    La tête 15 du bras télescopique 7 est pourvue d'un dispositif de liaison 24, destiné à recevoir divers équipements de travail interchangeables, ainsi fixés à l'extrémité avant du bras 7. L'équipement de travail peut être notamment un godet 25 (figures 2 et 6), un crochet fixe ou un treuil de levage 26 (figure 3), une fourche 27 (figures 4, 5 et 6) ou une nacelle élévatrice de personnel 28 (figure 7).The head 15 of the telescopic arm 7 is provided with a link 24, for receiving various work equipment interchangeable, thus attached to the front end of the arm 7. The equipment of work can be in particular a bucket 25 (FIGS. 2 and 6), a hook fixed or lifting winch 26 (Figure 3), a fork 27 (Figures 4, 5 and 6) or a personnel lift nacelle 28 (FIG. 7).

    En position repliée de transport , comme le montre la figure 1, la rehausse 6 est abaissée sensiblement à l'horizontale, et elle repose sur la structure d'appui 19. Le bras télescopique 7 est rétracté, et replié au-dessus de la rehausse 6. La cabine 8 est abaissée, et elle se situe à l'avant du châssis tournant 4, sur le côté de la rehausse 6 et du bras 7. De plus, dans l'utilisation ici illustrée, la tête 15 du bras 7 et le godet 25 prennent place en avant du châssis de base 1.In the folded transport position, as shown in FIG. the riser 6 is lowered substantially horizontally, and it rests on the support structure 19. The telescopic arm 7 is retracted, and folded over 6. Cab 8 is lowered, and it is at the front of the rotating frame 4, on the side of the riser 6 and the arm 7. In addition, in the use shown here, the head 15 of the arm 7 and the bucket 25 take place in front of the base frame 1.

    La figure 3 illustre la cinématique générale de la rehausse 6 et du bras télescopique 7, résultant de leurs débattements respectifs permis par leurs axes d'articulation 9 et 16. En se référant ici à une application de manutention, la combinaison de ces débattements permet de couvrir quatre secteurs de manutention distincts, désignés I à IV, soit :

    • un secteur supérieur arrière I de manutention, dont l'enveloppe maximale est déterminée par la position " rehausse 6 sensiblement horizontale repliée vers l'arrière, bras 7 télescopé et aligné avec la rehausse 6 " et par la position " rehausse 6 verticale, bras 7 télescopé et aligné avec la rehausse 6 " ;
    • un secteur supérieur avant II de manutention, dont l'enveloppe maximale est déterminée par la position finale précédente et par la position " rehausse 6 sensiblement horizontale déployée vers l'avant, bras 7 télescopé et aligné avec la rehausse 6 " ;
    • un secteur inférieur avant III de manutention, dont l'enveloppe maximale est déterminée par la position finale précédente et par la position " rehausse 6 sensiblement horizontale déployée vers l'avant, bras 7 télescopé et sensiblement vertical, dirigé vers le bas " ;
    • un secteur inférieur arrière IV de manutention, dont l'enveloppe est déterminée par la position finale précédente et par la position " rehausse 6 sensiblement horizontale déployée vers l'avant, bras 7 télescopé et en position inclinée de manière à s'étendre sous la rehausse 6 " (l'inclinaison maximale du bras 7 par rapport à la verticale est théoriquement de 90°, mais elle est en pratique limitée par l'environnement).
    FIG. 3 illustrates the general kinematics of the riser 6 and the telescopic arm 7, resulting from their respective displacements allowed by their hinge axes 9 and 16. Referring here to a handling application, the combination of these displacements makes it possible to cover four distinct handling sectors, designated I through IV, that is:
    • a rear upper sector I handling, the maximum envelope is determined by the position "raises 6 substantially horizontally folded rearward, arm 7 telescoped and aligned with the riser 6" and the position "raises 6 vertical arm 7 telescoped and aligned with the 6 "riser;
    • an upper sector before II handling, the maximum envelope is determined by the previous final position and the position "raises 6 substantially horizontal deployed forward, arm 7 telescoped and aligned with the riser 6";
    • a lower sector before handling III, whose maximum envelope is determined by the previous final position and the position "raises 6 substantially horizontal deployed forward, arm 7 telescoped and substantially vertical, directed downwards";
    • a rear lower sector IV handling, whose envelope is determined by the previous final position and the position "raises 6 substantially horizontal deployed forward, arm 7 telescoped and inclined to extend under the riser 6 "(the maximum inclination of the arm 7 relative to the vertical is theoretically 90 °, but it is in practice limited by the environment).

    L'articulation de la rehausse 6 et/ou du bras 7, et le télescopage de ce bras 7, permettent de couvrir l'aire totale de chacun des secteurs I, II, III et IV, comme l'illustrent les positions intermédiaires indiquées sur la figure 3, ainsi que les flèches F symbolisant ici le mouvement de télescopage. L'addition des quatre secteurs, précédemment définis, détermine un plan vertical de manutention (plan de la figure 3). L'orientation du châssis tournant 4 autour de l'axe vertical 5 engendre dans l'espace, à partir de ce plan, un certain volume de manutention.The articulation of the extension 6 and / or the arm 7, and the telescoping of this arm 7, make it possible to cover the total area of each of the sectors I, II, III and IV, as illustrated by the intermediate positions shown in Figure 3, as well as the arrows F symbolizing here the telescoping movement. The addition of the four sectors, previously defined, determines a vertical handling plane (plane of Figure 3). The orientation of the rotating frame 4 about the vertical axis 5 generates in space, from this plane, a certain volume of handling.

    La figure 4 illustre, plus précisément, l'utilisation du chariot automoteur avec sa rehausse 6 repliée vers l'arrière, et reposant sur la structure d'appui 19 présente à l'arrière du châssis tournant 4. Le bras 7 peut ici pivoter, autour de l'axe horizontal 16 maintenu fixe, entre une position sensiblement horizontale et une position sensiblement verticale, ce bras 7 pouvant, de plus, être télescopé. Le chariot automoteur est ainsi utilisable comme un engin à simple bras télescopique, par exemple pour la manutention d'une charge 29 posée sur une fourche 27.Figure 4 illustrates, more precisely, the use of the trolley self-propelled with its raising 6 folded backwards, and resting on the support structure 19 present at the rear of the rotating frame 4. The arm 7 here can rotate, around the horizontal axis 16 held fixed, between a substantially horizontal position and a substantially vertical position, this arm 7 can, moreover, be telescoped. The self-propelled carriage is thus can be used as a machine with a single telescopic arm, for example for the handling a load 29 placed on a fork 27.

    Le chariot automoteur est utilisable aussi, comme le montre la figure 5, avec sa rehausse 6 déployée verticalement, le bras télescopique 7 pouvant posséder une inclinaison variable, et être plus ou moins télescopé. L'engin peut ainsi assurer la distribution d'une charge 29 au-dessus d'un bâtiment bas 30, ou au-delà d'un obstacle tel que mur. Dans cette position d'utilisation, la cabine 8 est avantageusement amenée en position haute, sensiblement au niveau de l'extrémité supérieure de la rehausse 6, l'axe de vision 31 de l'opérateur passant alors au-dessus du bâtiment 30 ou autre obstacle, de manière à conserver la vision directe de la charge 29 au cours de la manutention de celle-ci.The self propelled trolley can also be used, as shown in FIG. 5, with its riser 6 deployed vertically, the telescopic arm 7 can have a variable inclination, and be more or less telescope. The machine can thus ensure the distribution of a load 29 above a low building 30, or beyond an obstacle such as wall. In this position of use, the cabin 8 is advantageously brought into high position, substantially at the upper end of the raises 6, the axis of vision 31 of the operator then passing over the building 30 or other obstacle so as to maintain the direct vision of the load 29 during handling thereof.

    Comme le montre aussi la figure 5, le chariot automoteur est encore utilisable avec sa rehausse 6 déployée horizontalement vers l'avant, et prolongée par le bras télescopique 7, aligné horizontalement avec cette rehausse 6. Cette position d'utilisation permet la distribution d'une charge 29 par une ouverture 32 d'un bâtiment 30.As also shown in Figure 5, the self propelled trolley is still usable with its riser 6 deployed horizontally to the front, and extended by the telescopic arm 7, aligned horizontally with this enhancement 6. This use position allows the distribution a load 29 through an opening 32 of a building 30.

    La figure 6 illustre d'autres possibilités d'utilisation, permettant d'exécuter des travaux au-dessous du plan d'appui 33 du chariot automoteur. Ainsi, avec la rehausse 6 déployée vers l'avant, et avec le bras télescopique 7 dirigé vers le bas (tracé en traits mixtes), il est possible de distribuer une charge 29 au fond d'une excavation 34. Avec la rehausse 6 maintenue en position inclinée, et avec le bras télescopique 7 replié sur cette rehausse 6 (tracé en traits continus), il est possible de déplacer le godet 25 sur un plan incliné 35, pour des travaux de terrassement : construction d'un ouvrage incliné (talus de route, berge de canal, digue), réalisation d'une fouille. Bien entendu, selon l'équipement de travail porté par le bras télescopique 7, il est aussi possible d'effectuer la manutention de gravats, de palettes de matériaux, de béton, etc... le long du plan incliné 35.Figure 6 illustrates other possibilities of use, allowing to perform work below the support plane 33 of the truck propelled. Thus, with the extension 6 deployed forward, and with the telescopic arm 7 directed downward (in phantom lines), it is possible to distribute a load 29 at the bottom of an excavation 34. With the riser 6 held in an inclined position, and with the telescopic arm 7 folded on this enhancement 6 (drawn in continuous lines), it is possible to move the bucket 25 on an inclined plane 35, for work of earthworks: construction of an inclined structure (road embankment, bank of canal, dike), excavation. Of course, depending on the equipment of work carried by the telescopic arm 7, it is also possible to perform the handling of rubble, pallets of materials, concrete, etc ... along inclined plane 35.

    Enfin, la figure 7 illustre les possibilités d'utilisation du chariot automoteur, équipé d'une nacelle 28 maintenue horizontale, sur laquelle peuvent prendre place une ou plusieurs personnes. La nacelle 28 permet un travail en hauteur, dans les secteurs supérieurs arrière I et avant II (tels que précédemment définis), par exemple pour la pose de charpentes ou l'habillage de bâtiments, même dans des travées étroites n'autorisant pas la rotation complète du châssis tournant 4 autour de l'axe vertical 5. Comme l'illustre la figure 7, il est aussi possible, en amenant la nacelle 28 dans le secteur inférieur arrière IV, d'effectuer l'inspection des piles 36 et du tablier 37 d'un pont 38, le chariot automoteur étant positionné sur le pont 38 lui-même.Finally, Figure 7 illustrates the possibilities of using the truck self-propelled, equipped with a nacelle 28 maintained horizontal, on which can take place one or more people. The nacelle 28 allows work at heights, in the upper rear areas I and II (such as than previously defined), for example for the laying of frames or the dressing of buildings, even in narrow bays that do not allow the complete rotation of the rotating frame 4 about the vertical axis 5. As illustrated in Figure 7, it is also possible, by bringing the platform 28 in the lower rear area IV, to inspect the batteries 36 and of the deck 37 of a bridge 38, the self-propelled carriage being positioned on the bridge 38 itself.
