Definitions

  • the present invention relates to a load-handling arrangement incorporated in goods vehicles, such as lorries and trucks for instance and intended for loading and unloading load-units, by which is meant loads in the form of demountable skips, containers, cisterns and the like, said arrangement including a tilt-frame which is pivotally mounted on the rear part of the vehicle, and a carriage unit which is movable along the tilt-frame and which coacts with the load units, said ' carriage being manouvered with the aid of at least two mutually adja ⁇ cent hydraulic piston-cylinder assemblies which are interlinked mechanically so that the carriage can be moved through a distance corresponding substantially to the combined length of working stroke of the pi ⁇ ton- cylinder-a ⁇ semblies.
  • the goods vehicle is normally fitted with a robust frame which can be tilted about a tilting axle at the rear end of the vehicle, with the aid of hydraulic tilting piston-cylinder-assemblies.
  • the frame is tilted so as to form a given angle with the ground, whereafter the demountable load-unit i ⁇ drawn-up onto or pushed-down from the frame with the aid of a carriage which is movable along said frame and provided with a lifting-and-holding hook device intended for coaction with the demountable load-unit.
  • Movement of the carriage along the tilt-frame is normal ⁇ ly effected with the aid of a chain-driven mechanism of a kind similar to that used in fork-lift trucks.
  • One of the drawbacks with the use of chains is that chains require continuous maintenance, including lubrication and cleaning, resulting in high maintenance costs. Arrangements which incorporate chains also result in relatively high manufacturing costs and in heavy con- structions. It is of primary interest in the case of goods vehicles to reduce the weight of ancillary equip ⁇ ment, so as to increase correspondingly the weight of the useful load capable of being carried by the vehicle.
  • the main object of the present invention is to provide a relatively light and simple construction operative to move the carriage along a tilt-frame with the aid of hydraulic piston-cylinder-assemblies.
  • the construction shall also be configured so as to obviate the need for flexible hy ⁇ draulic lines for transferring hydraulic fluid between the various driven piston-cylinder-assemblies and be- tween said assemblies and auxiliary piston-cylinder- assemblie ⁇ mounted on the carriage.
  • an arrangement of the kind described in the first paragraph of the specification is particularly characterized in that the piston rods of the two piston- cylinder-assemblies are configured with two hydraulic- fluid passageways which communicate with space ⁇ on different sides of the piston in respective assemblies.
  • This construction enables fluid to be supplied to both the driving piston-cylinder-assemblies and the hydraulic devices mounted on the carriage with the aid of hydrau ⁇ lic lines of fixed lengths.
  • the two piston-cylinder-assemblies are fixated mechanically in relation to one another and are hydraulically connected in parallel with the aid of hydraulic lines of fixed lengths.
  • one piston rod is connected to the tilt-frame and the other piston rod to the carriage, and both of said piston rods are provided with means for connection to said fluid passageways at their outer ends.
  • An alternative embodiment which provides essentially the same advantages is characterized in that one piston- cylinder-assembly is connected to the tilt-frame, in that the second piston-cylinder-assembly i ⁇ connected to the piston rod of the first piston-cylinder-assembly, in that the piston rod of the second piston-cylinder-as ⁇ e - bly i ⁇ connected to the carriage, and in that the la ⁇ t mentioned pi ⁇ ton rod i ⁇ provided with mean ⁇ for connec- tion to said fluid passageways at its outer end .
  • said one piston-cylinder-as ⁇ embly i ⁇ provided with fixed connections for pressure fluid and return fluid.
  • the fluid passageways in the piston rod connected to the carriage are preferably connected with hydraulic devices mounted on the carriage, said connection being effected via electrically switchable valve devices.
  • These hydrau- lie devices may include devices for lifting a load unit onto the tilt-frame, and can be subjected to pressure so as to carry-out a lifting movement when the piston rods are urged to their retracted positions in respective cylinders.
  • the lifting device ⁇ preferably include a gripping hook having a pivotal locking arm which is intended to close the hook in coaction with the load unit to be lifted, thereby providing a reliable, self-locking function.
  • the arrangement includes at least one tele ⁇ scopic piston-cylinder-assembly operative to initiate tilting of said frame, and that the position of the outer end of the piston rod of said telescopic pi ⁇ ton- cylinder-assembly is controlled with the aid of a rod which i ⁇ pivotable about the tilting axle of the frame, said end of ⁇ aid pi ⁇ ton rod coacting with a ⁇ eat on ⁇ aid frame.

Abstract

L'invention concerne un dispositif disposé dans des véhicules destinés à manipuler des unités de charge, par exemple, des skips, des conteneurs, des citernes et autres dispositifs porteurs de charge. Ledit dispositif comprend une ossature basculante (3) montée de façon pivotante sur la partie arrière du véhicule (1) ainsi qu'un porteur (7) mobile sur ladite ossature destiné à agir de concert avec les unités de charge (2). On prévoit également au moins deux ensembles de piston-cylindre hydrauliques mutuellement adjacents (8, 9) pour man÷uvrer le porteur (7). Lesdits ensembles sont reliés mécaniquement pour permettre le déplacement dudit porteur (7) sur une distance correspondant sensiblement aux longueurs combinées de course des ensembles de piston-cylindre. Selon l'invention, les tiges de piston (10, 11) des deux ensembles (8, 9) sont pourvues de passages pour fluides hydrauliques (21 26; 22, 27) communiquant avec des espaces situés aux côtés mutuellement différents desdits pistons (24, 25) logés dans les cylindres respectifs.
