Mr Mike Durban, 7535 Königsbach Lifting vehicle, especially trailer. Description

The innovation relates to a lifting vehicle, in particular a trailer for riding horses, where the vehicle frame, in particular the trailer frame, is U-shaped and open at the rear.

According to DE-OS 25 35 495, for example, such a lifting trailer is known for transporting loads, which has a U-frame located inside the wheels and a loading box that can be raised, lowered and tilted. In this construction, the lifting, lowering and tilting

IQ tipping loading areas between the frames are relatively narrow and there is no wheel suspension. There are a number of trailers of this type, especially for agricultural purposes, as well as various forms of tipping loading surfaces in such trailers. In the latter case However, this results in a necessary inclination of the entire loading area.

The aim of the innovation is to create a lifting and lowering loading case especially for racehorses, which

for bringing the horses in and out on the ground

&egr; can be parked and with a suspended wheel

f suspension nevertheless the entire width between the wheels

This ensures a secure entry

^? ; 5 and release of the valuable racehorses with sufficient

the parking space while driving.

i\ To solve this task, the hub vehicle, in particular trailer for riding horses, whereby the vehicle, in particular trailer frame is U-shaped and open at the rear, according to the innovation in that the frame legs on both sides run the side edges by means of a U-shaped bend, preferably in a tandem arrangement, which wheels are each suspended on the one hand on supports of the frame IS bend by means of longitudinal control arms and on the other hand by means of damping spring arms - shock absorbers - in such a way that the entire space between the wheels remains for a lowerable loading area - loading box. Here, the longitudinal control arms with the damping spring arms form a corresponding suspension

-* variable angle to each other, whereby both the

Both the trailing arm arms and the damping spring arms are hinged at an angle to the frame plane within the bend.

Further details of the innovation can be found in the preferred embodiments of lifting trailers shown in the drawing and described below, namely:

Figure 1 is a plan view of the base frame of such a lifting trailer,

Figure 2 is a side view with the charging case lowered,

Figure 3 is a perspective view of a further embodiment and

Figure 4 is a perspective view of a final embodiment of such a lifting trailer.

As can be seen from the drawing of the first embodiment Figures 1 and 2, the lifting trailer consists from a U-shaped main frame open to the rear with the usual coupling part 2 for the towing vehicle. The frame legs 3 on both sides are each bent at 4 and run over the tandem wheels 5. These wheels 5 are in turn attached to supports 6 of the frame cranking by means of longitudinal control arms 7 and Damping spring arms 8 with built-in shock absorber 9 are suspended in a spring-loaded manner. The loading box 10 is arranged in the space between the wheels 5 and can be lowered. The longitudinal control arms and the damping spring arms 8 form a corresponding

Suspension variable angle, whereby both

the longitudinal spring arms 7 as well as the damping spring arms are hinged at an angle to the frame plane within the bend 4.

The longitudinal control arms 7 and damping spring arms 8 run as flat steel arms on the inside next to the wheels 5 and are provided with bends 11 or widenings on the wheel circumference for wheel suspension. Here, on both sides of the bend 4, a pneumatic or hydraulic cylinder 12 is mounted for vertically raising or lowering the loading box 10 resting on the trailer frame 1 by means of side flanges 13. Between the bent frame part 4 and the two

Pneumatic or hydraulic cylinders 12 is a

known scissor rod connection 14 with fixing in the lower lowering area and pivot pin of the scissors as a stop 16 in the upper lifting area. This overall structure according to the innovation thus results in a on the one hand, the possibility of lowering the loading box for parking on the ground and raising it accordingly into the driving position with the largest possible loading area.

In the second embodiment according to Figure 3, the lifting trailer, as can be seen from the drawing, also consists of a U-shaped trailer frame that is open at the back with a conventional coupling part 22 for the towing vehicle. The frame legs 23 on both sides are also bent at 24 and run here over the tandem wheels 25, which in turn are suspended on supports 26 of the frame bend 24 by means of longitudinal control arms 27 and damping spring arms 28 with built-in shock absorbers 29. The loading box 30 is thus arranged in a lowerable manner in the space between the wheels 25. Here too, the

Trailing arm arms 27 and the damping spring arms 28 form a right angle to one another that can be changed according to the suspension, with both the trailing arm arms 27 and the damping spring arms 28 being hinged at an angle to the frame plane within the bend 24.

Q The trailing arm 27 and the damping spring arms 28

run inside next to the wheels 25 and extend with extensions or bends 31 over the Wheel circumference for their suspension. Here, a second U-shaped lifting frame 32 - without offset - is provided above the U-shaped trailer frame 21 to support the loading box 30 with lockable side bearing bolts 33. This lifting frame 32 is preferably attached to the base frame 21 on both sides. guided vertically in U-profiles 35 by means of roller 34 and height-adjustable by means of a pneumatic or hydraulic cylinder 36 located between them. The cylinder has a roller 38 on its piston rod 37, over which (38) a chain belt 39 runs, which on the one hand is Hanger frame 21 at 39a and on the other hand is firmly attached to the lifting frame 32 at 39b and thus causes a double stroke compared to the piston stroke when the lifting is actuated. In addition, a chain belt 40 runs on both sides over the frame part bent at 24, which is in each case at the front is attached to the lifting frame 32 at 40a on the side and to a vertical additional guide of the same (32) in the form of a telescopic guide 41 at 40b on the rear and which^ (40) thus supports the lifting and lowering movement of the lifting frame 32.

The rear telescopic guide 41 is provided with a locking bolt 42 to ensure that the loading box 30 is locked in place when it is raised.

In the third embodiment according to Figure 4, the same structure is provided as in the second example, so that reference can be made to the previous description in this regard. Only the longitudinal control arm 27 and damping spring arm 28a, the latter with Leaf springs 29a and a variant is provided for the chain belts 40, which run on both sides over the cranked frame part 24 and are attached at the front to the lifting frame 32 at 40a and at the back to a rotatable additional guide of the same (32) in the form of a Pivoting lever 41a is attached to 40b and thus supports the lifting and lowering movement of the lifting frame 32 via the roller 42a.

Another advantage of this innovation is that the loading box 10 or 30 can be parked freely, i.e. you can set it down (10 or 30) and leave it there and drive away with the trailer 1,2 or 21,22 and only pick it up again after loading or unloading and in the meantime also transport another loading box
