Definitions
- the invention relates to a carriage motorized handling, especially of the kind capable of being on board the back of a carrier vehicle.
- carts suitable to be loaded on a carrier vehicle such as a truck, which can be used loading and unloading the truck and then be attached to the back of it for transportation.
- This kind of cart is generally of little realization bulky, so as to protrude from the truck by a small distance, its chassis being constructed so that the front wheels are near the front end of its loading fork.
- motorized handling trucks of the aforementioned type generally include a chassis having a U-shaped configuration open towards the front, equipped with two front wheels and one rear wheel so that the lifting means extend thus in their most retracted position between the lateral branches of the U-shaped chassis.
- a general constraint for the design of truck mounted carts is that these carts must be as light as possible so as not to decrease notably the payload of the truck. This is the reason which on-board carts are generally without counterweights and designed so that the load is arranged between the wheel arms at the rear of the wheels front of the truck in transport position. However, he is necessary to be able to deposit or take charge on the truck bed if the front wheels are not can not pass under said plate, to provide auxiliary devices for advancing the loading forks in front of the front wheels: in this static position of loading, the load can be lifted by a trolley on board is substantially equal to the total weight at cart empty.
- Document US 4,826,474 describes a carriage motorized handling unit capable of being loaded at the rear of a carrier vehicle, while the document EP 325064 describes a self-propelled forklift which is not suitable for be on the back of a carrier vehicle.
- on-board carts of known type are generally produced in the form of a double-effect vertical mast carriage: this double-acting vertical mast allows handling and transport and also facilitates the loading of the trolley the rear of the truck using a known technique for example according to document FR 2 298 454.
- the ancillary devices known for moving the forks at the front of the front wheels in the case of a grip load in front of the front wheels are of the fork type telescopic, fork extender, or mast retractable.
- each telescopic fork has a sliding sleeve on a support guided by slides or rollers and driven by a jack synchronized with the deployment of the other fork.
- This arrangement had the disadvantage that the telescopic forks are subjected to a rapid wear by friction in contact with the ground and requires keep the forks perfectly horizontal when they are in the deployed position, because the load located far from the load backrest and the apron of the mast, is likely to slide abruptly until load backrest and thus cause accidents undesirable.
- this provision leads to high manufacturing costs and maintenance costs important for operational reliability relatively small.
- a deformable scissor structure connects the vertical mast and the apron supporting the forks, thus displacing the forks horizontally forward when deformation of the scissor structure.
- This system presents on the one hand the disadvantage of increasing the total overshoot from the carriage to the rear of the truck, from a distance corresponding to the length of the deformable structure at scissors in the folded position, which increases the length of the total rolling assembly including the carrier vehicle and the on-board cart, and on the other hand the disadvantage of reducing the payload of the vehicle corresponding carrier of the additional weight added by the presence of this deformable structure with scissors.
- the front forks are deported from the mast of the value corresponding to this spacing, which reduces the transport capacity of truck load; while in loading position static on site, the payload of the truck is reduced due to the displacement of the center of gravity resulting from the additional weight of the deformable scissor structure, weight applied in front of the front wheels.
- the mast In retractable mast devices, the mast is mounted on a structure that slides inside the carriage chassis.
- This layout has the same disadvantages that the fork extensor system in due to the fact that the forward displacement of the assembly comprising the mast and its supporting structure causes a significant forward movement of the center of gravity of the carriage, displacement resulting in a reduction notable load carrying capacity and stability in static loading on site.
- mast trolleys vertical which is not covered by the present invention, move the load-bearing forks sideways to position in correspondence with the charges to handle.
- the lateral movement of the entire lifting structure comprising a vertical mast carrying one or more aprons can also be made in relation to the supporting frame by appropriate means.
- the implementation of the lateral displacement of the forks requires setting up intermediate decks or load-bearing structures important intermediaries that increase the cost of forklift and in particular increase its weight total laden, so the payload of the truck is reduced to total weight under constant load, and so that the manufacturing cost of the cart is increased by noticeably.
- the object of the invention is to remedy the aforementioned drawbacks of the prior art, by creating a new motorized handling cart capable of being on the back of a carrier vehicle so simple and fast.
- the invention also aims to apply the principle of lateral displacement of the supporting structure at trolley with telescopic arm, without significant increase mechanical organ, while allowing exploitation presenting the same performances as those of art prior.
- a trolley according to the invention comprises a chassis 1 having a U-shaped configuration opening towards the front, a line 2, a powertrain 3 and means for lifting 4.
- a branch 1a of the chassis carries a front wheel 5 while the other branch 1b carries the other front wheel 6.
- the rear steering wheel 7 is mounted substantially at the middle of the main body of the chassis. Rear wheel steering 7 is controlled by a steering wheel 8 located in the operator station 2 which also includes all the components for controlling the lifting means 4.
- the powertrain 3 is preferably a group comprising a heat engine driving a pump hydraulics, distribution and control components necessary being grouped with powertrain 3 and controlled directly from the cockpit 2.
- the lifting means 4 have a telescopic arm 9 pivotally mounted around a substantially horizontal axis 10 located at the rear of the chassis 1 substantially above the rear wheel director 7.
- the control and driving position is located on one side of the truck, the powertrain 3 is located side opposite to the control and driving position, and the arm telescopic 9 in its lowered and retracted position corresponding to the transport of a load passes between the operator station 2 and powertrain 3.
- This arrangement thus provides excellent visibility on the load and on the lifting means 4, unlike the arrangement of the prior art where the mast retractable obstructed operator visibility.
- the telescopic arm 9 carries at its end distant from the pivot axis 10 a gripping member 11 swiveling about a horizontal axis 12 under the action of an actuating cylinder not shown and of a type known per se.
- the gripping member 11 is preferably shaped like an apron supporting forks 13a, 13b.
- the forks 13a, 13b can start from the lowered position and retracted from the telescopic arm 9 corresponding to the transport of a charge and shown in solid lines, to go to other horizontal or tilted positions digging or a direction of discharge shown in lines dotted.
- the telescopic arm 9 is extendable under the action an internal cylinder not shown and pivots under the action a lifting cylinder 14 disposed laterally relative to the arm and fixed to a bracket fixed to the beam of the arm telescopic 9.
- the trolley is advantageously fitted according to the invention of a compensation cylinder, capable of maintaining the forks 13a, 13b horizontal during transport of the load in case of carriage movement on ground crashed.
- the lifting cylinder 14 and the cylinder compensation 15 are mounted on either side of the beam of the telescopic arm 9, in one position does not interfere with driver visibility when the telescopic arm 9 is in the transport position, fully lowered and retracted.
- all of the lifting means 4 can be moved transversely from a distance predetermined d so as to allow precise adjustment of the positioning of the lifting means during gripping of the load.
- the lifting means 4 comprising the arm telescopic 9 are movable on the stroke d according to a controlled and preferably controlled movement hydraulically under the action of means of translation arranged in the vicinity of the pivot axis 10.
- the actuating means hydraulics include at least one hydraulic cylinder, of which the direction of actuation is substantially parallel to the pivot axis 10.
- a carriage according the invention presents a stability diagram without crutch corresponding to the lifting of a load of 9000 N at a distance of 1 meter in front of the front wheels: thus obtains performances equivalent to or better than those of on-board carriages of the prior art.
- the carts according to the invention have a range at the front of the wheels significantly higher than the carts prior art.
- Figure 5 shows a stability diagram with stand even better compared to the diagram stability without stand in Figure 4 and relative to characteristics of the on-board carriages of the prior art, in the case where one equips a trolley according to the invention of 16 retractable stabilizers able to come to bear on the ground in front of the contact point P of a front wheel 5 with the ground.

- a method of loading a trolley according to the invention and securing to a carrier vehicle comprises the steps described below.
- the carriage then rests under the effect of its own weight on the support 21 on which it is applied by the telescopic arm in fully retracted position: the balancing position of the machine load according to the invention embedded in the back of the carrier vehicle is perfectly stable and allows transport over long distances.
- a means is provided for additional locking of the truck mounted on the carrier vehicle with the support 21 secured to the vehicle carrier.
- This locking means can for example have two side locks controlled directly from the by means of a lever arranged in the driving station 2 and control unit. These side locks can be mechanical or hydraulic locks, or electrically operated.
- the means lock is controlled by stopping the engine trolley or the interruption of electric power to the trolley, or the hydraulic power interruption of the truck.
