Description

Engin de levage et procédé d'utilisation d'un tel engin de levage  Lifting apparatus and method of using such a lifting apparatus
L'invention concerne un engin de levage et un procédé d'utilisation d'un tel engin de levage. The invention relates to a hoist and a method of using such a hoist.
Les plateformes élévatrices mobiles de personnels comportent généralement un châssis sur lequel sont montées des roues, une nacelle et des moyens d'élévation de la nacelle. De telles plateformes élévatrices doivent être transportées d'un chantier à un autre par la route. Pour cela, leur largeur ne doit pas dépasser 2,50 m pour ne pas nécessiter un convoi exceptionnel. D'autre part, de telles plateformes élévatrices doivent parfois être transportées par voie maritime, notamment à l'intérieur d'un container. Cependant, les dimensions standards d'un container sont généralement inférieures à 2,50 m. Il est donc nécessaire de limiter la largeur maximale de la plateforme élévatrice spécifiquement pour le transport en container. Cela revient à réduire la voie, c'est-à-dire la distance transversale entre les roues de chaque côté du châssis de la plateforme élévatrice. Cette solution n'est pas satisfaisante, car la voie est un paramètre important pour la stabilité d'une plateforme élévatrice et donc pour ses performances et sa sécurité d'utilisation. Pour maintenir la stabilité en réduisant la voie, un poids supplémentaire peut être rajouté, mais cette solution est peu pratique et coûteuse.  The mobile elevating platforms of personnel generally comprise a frame on which are mounted wheels, a nacelle and means of elevation of the nacelle. Such lifting platforms must be transported from one site to another by road. For this, their width must not exceed 2.50 m to not require an exceptional convoy. On the other hand, such lifting platforms must sometimes be transported by sea, especially inside a container. However, the standard dimensions of a container are generally less than 2.50 m. It is therefore necessary to limit the maximum width of the lifting platform specifically for container transport. This amounts to reducing the track, that is to say the transverse distance between the wheels on each side of the frame of the lifting platform. This solution is not satisfactory because the track is an important parameter for the stability of a lifting platform and therefore for its performance and safety of use. To maintain stability by reducing the track, additional weight can be added, but this solution is impractical and expensive.
Le même problème se pose également pour des engins de levage autres que les plateformes élévatrices, tels que les chariots élévateurs.  The same problem also arises for lifting gear other than lifting platforms, such as forklifts.
Il est également connu de remplacer les roues normales par des roues métalliques de plus faible largeur, ou galettes. Cependant, ces galettes sont jetées après usage, ce qui implique un surcoût important. En outre, si la plateforme élévatrice est utilisée sans avoir remplacé les galettes par les roues normales, les performances de stabilité et de sécurité de la plateforme élévatrice sont dégradées et un risque de reversement survient.  It is also known to replace the normal wheels with metal wheels of smaller width, or slabs. However, these patties are discarded after use, which implies a significant additional cost. In addition, if the lift platform is used without having replaced the wafers by the normal wheels, the stability and safety performance of the lifting platform are degraded and a risk of reversal occurs.
C'est à ces inconvénients qu'entend remédier l'invention en proposant un nouvel engin de levage dont les dimensions peuvent être adaptées de façon simple au transport par container, tout en garantissant ses performances et sa sécurité d'utilisation.  It is these drawbacks that the invention intends to remedy by proposing a new lifting gear whose dimensions can be adapted in a simple way to transport by container, while ensuring its performance and safety of use.

Cet engin de levage est caractérisé en ce que les voiles radiaux des jantes sont décalés axialement vers l'un des bords latéraux des roues par rapport à un plan médian de chaque roue, en ce que les roues sont adaptées pour être montées sur les essieux dans une première position, correspondant à une configuration d'utilisation de la plateforme élévatrice, dans laquelle les plans médians sont éloignés du châssis, et dans une seconde position, correspondant à une configuration de transport de la plateforme élévatrice, dans laquelle les plans médians sont rapprochés du châssis, et en ce que l'engin de levage comprend des moyens de signalisation de la position de montage des roues et/ou des moyens de limitation de l'élévation du support de charge lorsque les roues sont dans leur seconde position. For this purpose, the invention relates to a hoist comprising a chassis, wheels mounted on axles of the chassis, each wheel comprising a rim having a radial web attached to a rotary member at one end of one of the axles , a load carrier and means for raising the load carrier. This hoist is characterized in that the radial webs of the rims are offset axially towards one of the lateral edges of the wheels relative to a median plane of each wheel, in that the wheels are adapted to be mounted on the axles in a first position, corresponding to a configuration of use of the lifting platform, in which the median planes are remote from the frame, and in a second position, corresponding to a transport configuration of the lifting platform, in which the median planes are brought closer to the frame, and in that the lifting gear comprises means for signaling the mounting position of the wheels and / or means for limiting the elevation of the load support when the wheels are in their second position.
Grâce à la structure et aux deux possibilités de montage des roues, la largeur de l'engin de levage peut être réduite pour le transport dans un container, tandis que les performances et la stabilité d'utilisation sont garanties lorsque les roues sont montées dans leur configuration d'utilisation. La présence de moyens de signalisation de la position de montage des roues et/ou de moyens de limitation de l'élévation du support de charge lorsque les roues sont dans leur seconde position permet de sécuriser l'utilisation de l'engin de levage.  Thanks to the structure and the two wheel mounting options, the width of the hoist can be reduced for transport in a container, while the performance and stability of use are guaranteed when the wheels are mounted in their container. usage configuration. The presence of means for signaling the mounting position of the wheels and / or means for limiting the elevation of the load support when the wheels are in their second position makes it possible to secure the use of the hoist.

FIG. 1 represents a lifting machine, a lifting platform 1 in this example, comprising a frame 3, a load support formed by a nacelle 5 and lifting means of the nacelle 5 formed by an articulated arm 7.
La plateforme 1 comprend des roues 9 montées sur des essieux 30 appartenant au châssis 3. Les essieux 30 sont creux et fixés de façon non rotative sur le châssis 3. Des moteurs hydrauliques 34 sont fixés à l'intérieur des essieux 30 aux extrémités 32 des essieux 30. Les moteurs hydrauliques 34 comprennent des arbres de sortie 340 qui définissent des axes de rotation X-X' des roues 9. Les roues 9 sont montées sur les axes de sortie 340 par l'intermédiaire de réducteurs de vitesse 342. Les arbres de sortie 340 et les réducteurs 342 forment des éléments rotatifs solidaires des essieux 30, et sur lesquels les roues 9 sont montées. Les axes de rotation X-X' définissent la direction transversale de la plateforme élévatrice 1 . The platform 1 comprises wheels 9 mounted on axles 30 belonging to the chassis 3.

The hydraulic motors 34 comprise output shafts 340 which define axes of rotation XX 'of the wheels 9. The wheels 9 are mounted on the output shafts 340 by means of speed reducers 342. The output shafts 340 and the reducers 342 form integral rotational elements of the axles 30, and on which the wheels 9 are mounted. The axes of rotation XX 'define the transverse direction of the lifting platform 1.
Dans la présente description, les termes « radial », « axial », « axialement » et « radialement » sont employés en référence aux axes de rotation X-X'.  In the present description, the terms "radial", "axial", "axially" and "radially" are used with reference to the axes of rotation X-X '.
Chaque roue 9 comprend une jante 90 présentant une partie axiale 91 sur laquelle est monté un pneumatique 93, et un voile radial 92 s'étendant à l'intérieur de la partie axiale 91 et qui est fixé sur un réducteur 342.  Each wheel 9 comprises a rim 90 having an axial portion 91 on which is mounted a tire 93, and a radial web 92 extending inside the axial portion 91 and which is fixed on a gear 342.
Les roues 9 présentent deux bords latéraux 94 et 95. Conformément à l'invention, les voiles radiaux 92 sont décalés axialement vers le bord latéral 95 des roues 9 par rapport à un plan médian P9 de chaque roue 9.

This confirmation of operation allows the greatest stability to the platform 1.
Les roues 9 sont adaptées pour être montées sur les essieux 30 dans une seconde position, représentée à la figure 6, correspondant à une configuration de transport de la plateforme élévatrice 1 . Dans cette configuration, les bords latéraux 95 sont situés du côté externe des roues 9, à l'opposé du châssis 3, et les plans médians P9 sont rapprochés du châssis 3 de sorte que les extrémités 32 des essieux 30 sont engagées dans les roues 9 de façon plus importante que dans la configuration de fonctionnement. En effet, sur la figure 6, les plans P9 passent dans les réducteurs 342, tandis que sur la figure 5, dans la configuration d'utilisation, les plans P9 passent axialement au-delà des réducteurs 342 vers l'extérieur. Dans cette configuration de transport, la plateforme 1 présente une largeur minimale Lm inférieure à la largeur maximale LM.  The wheels 9 are adapted to be mounted on the axles 30 in a second position, shown in FIG. 6, corresponding to a transport configuration of the lifting platform 1. In this configuration, the side edges 95 are located on the outer side of the wheels 9, opposite the frame 3, and the median planes P9 are close to the frame 3 so that the ends 32 of the axles 30 are engaged in the wheels 9 more importantly than in the operating configuration. In fact, in FIG. 6, the planes P9 pass through the gearboxes 342, whereas in FIG. 5, in the configuration of use, the planes P9 pass axially beyond the gearboxes 342 to the outside. In this transport configuration, the platform 1 has a minimum width Lm less than the maximum width LM.
De préférence, pour chaque roue 9, le voile radial 92 est situé à une distance D95 du bord latéral de la roue 9 dont il est le plus proche, c'est-à-dire le bord latéral 95, correspondant à une valeur comprise entre 10 et 40 % de la largeur totale L9 de la roue 9.  Preferably, for each wheel 9, the radial web 92 is located at a distance D95 from the lateral edge of the wheel 9 which it is closest to, that is to say the lateral edge 95, corresponding to a value between 10 and 40% of the total width L9 of the wheel 9.
Conformément à l'invention, la plateforme élévatrice 1 comprend également des moyens de signalisation de la position de montage des roues 9 et/ou des moyens de limitation de l'élévation de la nacelle 5 lorsque les roues 9 sont dans leur seconde position de montage. According to the invention, the lifting platform 1 also comprises means for signaling the mounting position of the wheels 9 and / or the means of limitation of the elevation of the nacelle 5 when the wheels 9 are in their second mounting position.
Dans l'exemple représenté, la plateforme 1 comprend des moyens de limitation de l'élévation de la nacelle lorsque les roues 9 sont dans leur position de la figure 6. En effet, lorsque les roues 9 sont dans leur position de la figure 6, la largeur de la plateforme élévatrice 1 est réduite, ce qui provoque une réduction de la stabilité de la plate-forme élévatrice 1 lorsque la nacelle 5 s'élève. Afin de limiter l'élévation de la nacelle 5, la plateforme élévatrice 1 comprend des sangles 1 1 passant sur les moyens d'élévation 7, et dont les extrémités 1 10 sont fixées sur les essieux 30 de telle manière que les sangles 1 1 ne peuvent pas être retirées sans auparavant démonter les roues 9.  In the example shown, the platform 1 comprises means for limiting the elevation of the nacelle when the wheels 9 are in their position of Figure 6. Indeed, when the wheels 9 are in their position of Figure 6, the width of the lifting platform 1 is reduced, which causes a reduction in the stability of the lifting platform 1 when the nacelle 5 rises. In order to limit the elevation of the nacelle 5, the lifting platform 1 comprises straps 1 1 passing on the elevating means 7, and whose ends 1 10 are fixed on the axles 30 so that the straps 1 1 do not can not be removed without first removing the wheels 9.
Les extrémités 1 10 comprennent des boucles dont le périmètre est inférieur au périmètre des roues 9, ce qui implique que les roues 9 doivent être démontées, puis les sangles 1 1 retirées, avant que les moyens d'élévation 7 de la nacelle 5 puissent être actionnés.  The ends 1 10 comprise loops whose perimeter is less than the perimeter of the wheels 9, which implies that the wheels 9 must be disassembled, then the straps 1 1 removed, before the lifting means 7 of the nacelle 5 can be actuated.
De préférence, les moyens de limitation de l'élévation de la nacelle 5 lorsque les roues 9 sont dans leur seconde position de montage, sont adaptées pour empêcher l'élévation de la nacelle 5 d'une hauteur correspondant à 30% de la hauteur maximale d'élévation. De cette façon, la hauteur maximale d'élévation reste dans les limites de stabilité autorisées par la configuration de transport, ce qui augmente la sécurité d'utilisation de la plateforme élévatrice 1 .  Preferably, the means for limiting the elevation of the nacelle 5 when the wheels 9 are in their second mounting position, are adapted to prevent the elevation of the nacelle 5 by a height corresponding to 30% of the maximum height. elevation. In this way, the maximum height of elevation remains within the stability limits allowed by the transport configuration, which increases the safety of use of the aerial platform 1.
De façon optionnelle, le châssis 3 comprend des orifices 36 de guidage et de passage des sangles 1 1 facilitant leur montage sur les essieux 30.  Optionally, the frame 3 comprises orifices 36 for guiding and passing the straps 1 1 facilitating their mounting on the axles 30.
Le procédé d'utilisation de la plateforme élévatrice 1 est décrit comme suit. Dans une configuration initiale de transport, la nacelle 5 est en position basse et les roues 9 sont montées dans leur seconde position, en configuration de transport de la nacelle élévatrice 1 . Préalablement au montage des roues en configuration de transport, les sangles 1 1 ont été mises en place en passant les boucles des extrémités 1 10 sur les essieux de manière que les sangles 1 1 se croisent sur les moyens d'élévation 7, rendant impossible l'élévation de la nacelle 5.  The method of using the elevating platform 1 is described as follows. In an initial transport configuration, the nacelle 5 is in the low position and the wheels 9 are mounted in their second position, in the transport configuration of the aerial platform 1. Prior to the mounting of the wheels in the transport configuration, the straps 1 1 have been put in place by passing the loops of the ends 1 10 on the axles so that the straps 1 1 cross on the elevating means 7, making it impossible to elevation of the nacelle 5.
Lorsque la plateforme élévatrice 1 doit être utilisée, les roues 9 sont préalablement démontées. Ensuite, les sangles 1 1 sont retirées des essieux 30. Les roues 9 sont ensuite remontées sur les essieux 30 dans leur première position, pour obtenir la configuration d'utilisation de la plateforme élévatrice 1 .  When the lifting platform 1 is to be used, the wheels 9 are dismounted beforehand. Then, the straps 1 1 are removed from the axles 30. The wheels 9 are then raised on the axles 30 in their first position, to obtain the configuration of use of the lifting platform 1.

Dans l'exemple représenté, la plateforme élévatrice 1 comprend également des moyens de signalisation 13 de la position de montage des roues 9, représentés à la figure 4. Ces moyens de signalisation 13 comprennent des signes distinctifs prévus sur les roues 9 et visibles depuis les côtés de la plateforme élévatrice 1 lorsque les roues 9 sont dans leur seconde position de montage. Les moyens de signalisation 13 sont de préférence prévus sur un côté 920 des voiles radiaux 92 orienté du côté du bord latéral 95, c'est-à-dire du côté du bord latéral qui se trouve vers l'extérieur lorsque les roues 9 sont dans leur seconde position de montage. Ces signes distinctifs comprennent par exemple des signaux d'alerte 130 permettant de signaler que les roues 9 sont montées dans leur position correspondant à la configuration de transport. Les moyens de signalisation 13 peuvent également comprendre des phrases d'avertissement 132 signalant la nécessité de modifier le montage des roues 9 avant toute utilisation normale de la plateforme 1 . According to a variant of the invention not shown, the lifting gear 1 may comprise only one strap January 1. In the example shown, the lifting platform 1 also comprises signaling means 13 of the mounting position of the wheels 9, shown in FIG. 4. These signaling means 13 comprise distinctive signs provided on the wheels 9 and visible from the sides of the lifting platform 1 when the wheels 9 are in their second mounting position. The signaling means 13 are preferably provided on a side 920 of the radial webs 92 oriented on the side of the side edge 95, that is to say on the side of the lateral edge which faces outwards when the wheels 9 are in their second mounting position. These distinctive signs include, for example, warning signals 130 making it possible to signal that the wheels 9 are mounted in their position corresponding to the transport configuration. The signaling means 13 may also include warning sentences 132 indicating the need to modify the mounting of the wheels 9 before normal use of the platform 1.
