Trailer for transporting a passenger car using a motor-driven pallet truck, in particular an electric low-lift truck

The present invention relates to a trailer for
Transporting a passenger car using a
motor-driven pallet truck, in particular electric low-lift truck.

According to the state of the art, forklifts are used to transport cars to be dismantled from one dismantling station to another when disposing of or recycling passenger cars. However, these have the disadvantage that they require large swivel and wide entry areas. Furthermore, overground and underground conveyor systems with rails are known, but these are very complex and therefore costly. In addition, such systems can be used to

The people to be dismantled

BOEHMERT & BOEHMERT

Motor vehicles can be easily transported from one dismantling station to another and lifted using a lifting platform, for example, in order to remove an engine. In particular, several passenger vehicles can be dismantled independently of one another at the same time. If necessary, passenger vehicles can be accommodated in "buffer zones" on the trailer according to the invention; and this without damaging the ground, for example by tires that have already been removed. This means that no fixed order has to be followed when dismantling the passenger vehicles. Passenger vehicles that require more time to dismantle can be removed if necessary.

Furthermore, the trailer is designed in such a way that it can be used across all types of passenger cars without any adjustment. Furthermore, the inventive design of the trailer ensures that, regardless of the type of passenger car, it is stable without damaging components in the area of the underbody of the passenger car, such as an exhaust or a cardan shaft.

It should also be noted that the trailer according to the invention has good steerability in the "semi-mounted" state due to the rigid design of the connecting device in combination with the rear axle with steering rollers.

Further features and advantages of the invention arise

from the claims and the following description, in which an exemplary embodiment is explained in detail using the schematic drawings. Shown here:

Fig. 1 is a perspective view of an embodiment of the trailer according to the invention in conjunction with an electric low-lift truck;

Fig. 2 a passenger car resting on the trailer of Fig. 1; and

Fig. 3 is a view of the coupling device of the trailer of Fig. 1.

Fig. 1 shows a perspective view of an embodiment of the trailer 10 according to the invention in conjunction with an electric low lift truck 12. In principle, instead of a lift truck, a motor-driven tractor, such as a three-wheel electric tractor, can also be used with minor modifications to the trailer according to the invention if necessary. The trailer 10 has a longitudinal support device 14 which comprises a rectangular frame. The sides 16 and 18 of the frame are significantly longer than the sides 20 and 22 of the frame. The frame is welded from rectangular hollow profiles and galvanized. On the longitudinal device 14, three cross members 24, 26 and 28 are arranged at right angles and in the middle with respective support elements 30, 32/34, 36/38, 40 on the tops of their ends, starting from the rear end of the longitudinal support device 14. The longitudinal dimensions of the rear 24 and front cross members 28 are less than those

that of the middle cross member 26 so that the support elements 30 and 32 as well as 38 and 40 do not reach into the chassis narrowing due to the wheel arch of a passenger car. The distances between the cross members 24 and 26 or 26 and 28 are chosen such that a small passenger car rests on the support elements 30, 32, 34 and 36 or 34, 36, 38, and 40 of at least two adjacent cross members 24 and 26 or 26 and 28. A limousine will rest on all three cross members 24, 26 and 28. The distance of the front cross member 28 to the front end of the longitudinal member device 14 is chosen such that, together with the free length available above the lifting device 42 in the form of a lifting fork of a lifting truck 12, there is sufficient space for the rear or Front section of a passenger car. The rear cross member 24 has a steering roller 46, 48 at its ends on its underside and the front cross member 28 has a rigid running wheel 50, 52 at its ends on its underside, resulting in two wheel axles. The steering rollers 46 and 48 are each screwed to a plate (not marked for reasons of clarity) which is welded to the underside of the rear cross member 24. In a corresponding form, the running rollers 50, 52 are each screwed to a plate (not marked for reasons of clarity) which is welded to the underside of the front cross member 28. The cross members 24, 26 and 28 as well as the support elements 30, 32, 34, 36, 38 and 40 have the same cross-sectional profile as the longitudinal support device 14. The cross members 24, 26 and 28 are closed at their ends and have rubber linings 54, 56, 58, 60, 62,

64. The support elements 30, 32, 34, 36, 38 and 40 also have rubber coatings 66, 68, 70, 72, 74, 76 on their upper sides. The height h of the support elements 30, 32, 34, 36, 38 and 40 is selected such that there is sufficient center clearance between the support elements 30, 32 or 34, 36 or 38, 40 of a respective cross member 24 or 26 or 28 and thus components located on the underside of the passenger car, such as an exhaust or a cardan shaft, are not damaged when the passenger car rests on them. The height b of the support surfaces of the support elements 30, 32, 34, 36, 38, 40 above the ground is selected such that a passenger car resting on the trailer has ground clearance, i.e. the associated wheels - even when the trailer 10 is "hitched up" - do not touch the ground. The longitudinal support device 14 has a device 86 at its front end for establishing a detachable, rigid connection with the lifting truck 12. This connection device 86 comprises a claw 88 at the front end of the longitudinal support device 14 and a complementary engagement element 90 which is welded onto the lifting device 42 of the lifting truck 12 (see Fig. 3). The engagement element 90 is arranged on the lifting device 42 in the form of a lifting fork in the area of the load wheels 92. When the lifting truck 12 with its lifting fork 42 is moved under the front end of the longitudinal support device 14 and the lifting fork 42 is slightly raised, the claw 88 and the engagement element 90 come into engagement, whereby the front wheel axle of the trailer 10 is raised at the same time. The trailer 10 can then be easily steered by the combination of a rigid connection with the steering rollers 46 and 48.

Fig. 2 shows the trailer 10 of Fig. 1 with a passenger car 94 resting on it. The passenger car 94 rests on all three cross members 24, 26 and 28. Since the passenger car 94 is relatively short, only the rear cross member 24 is located between the wheel arches of the front axle of the passenger car 94, while the front cross member 28 is located slightly in front of the wheel arches of the rear axle of the passenger car 94. In the present case, it is a compact car. If the passenger car is a sedan with a large trunk, there is sufficient space for the rear section between the front cross member 28 and the body of the lift truck 12.

The features of the invention disclosed in the preceding description, in the drawings and in the claims can be essential both individually and in any combination for the realization of the invention in its various embodiments.
