Description

The invention relates to an inclined lift truck of the type specified in the generic term of patent claim 1.

Inclined lift trucks are vehicle trailers, semi-trailers or trucks whose loading area/body can be lowered to the ground with its lower rear edge. The swivel axis is usually located on the front axle or the support point of the trailer. The distance from the swivel point to the rear edge of the loading area/body is possible.

The best possible angle is chosen in order to achieve a small angle of inclination when lowered. If this is in the order of 5-6°, larger goods can be transported onto the loading area or unloaded from there. The lowering and raising process of the loading area is usually carried out using a lifting mechanism on the rear axle of the vehicle or trailer. When raised, when the rear wheels of the double axle are unloaded, the cylinder device can change the track width of the rear axle so that the loading area can be lowered to the ground.

In the case of known inclined lift trucks of this type, which are known among other things from the published DB-P 30 31 353.2-21 and P 30 44 226.3-21, longitudinal swing arms pointing backwards in the direction of travel with wheels attached to them are shown in all cases. The change in the vehicle track is achieved by various measures.

The invention is based on the object of presenting an inclined lift truck of the generic type, simple construction, and two longitudinal swing arms with wheels attached to them on each side of the vehicle on the rear axle.

This object is achieved in an inclined pallet truck of the generic type according to the invention by the characterizing features of patent claim 1.

The particular advantage of an inclined lift truck according to the invention is that with a double cylinder on each

KBL-kr-le Tel.: 02863/ October 6, 1983 Mr. Kremer 20260

Two longitudinal swing arms with wheels attached to them are attached to the rear axle on the vehicle side. This arrangement means that two axles are held by one double ignition. The distance between the two wheels can be chosen so large that they form two axles in accordance with the regulations and laws.

The structural design according to the invention achieves a significant increase in the payload of an inclined pallet truck.

Certain advantageous design features of the invention emerge from the subclaims and the following description.

The invention is explained in more detail below with reference to the drawing of an embodiment:

Fig. 2 shows a section through the linkage of the longitudinal rockers to the cylinder device of the inclined lift truck according to Fig. 1,

Xn of the schematic side view of Fig. 1 recognizes

a rear wheel suspension of an inclined lift truck, in which

Explanation insignificant parts are not shown.

Fig. t shows a vehicle frame (7) which can, for example, consist of two longitudinal beams running along the underside of the structure close to the wheels. The cylinder device (1) is arranged between these longitudinal beams so that its heads (8) project laterally. The front (2) and rear (3) longitudinal swing arms are mounted on the heads (8). The front (2) and rear (3) longitudinal swing arms are extended beyond the wheels (4). The guide elements (9) are located at their ends. Furthermore, the additional guide (6) is located at the free end of the front longitudinal swing arm (2).

Fig. 2 shows the common bearing point on the cylinder head (8) of the front (2) and rear (3) longitudinal swing arms. The front longitudinal swing arm (2) is formed at the bearing point of the head (8) by a fork (5). The front (2) and rear (3) longitudinal swing arms are pivotally mounted. This means that the wheels are individually suspended and give the vehicle optimal driving characteristics on uneven ground.

Fig. 3 shows the area of the free end of the front longitudinal swing arm (2) to which the additional guide (6) is attached. The additional guide (6) is attached to the bushing on the longitudinal members, the loading area/structure (7) and the guide piece of the additional guide (6) on the front longitudinal swing arm (2). Laterally (transverse to the direction of travel)

KBL-kr-le Tel.: 02863/ October 6, 1983 Mr. Kremer 20260

In the guide rail (1) the bushing and guide piece fit precisely; there is play in the longitudinal direction to allow a swinging movement around the cylinder device (1) or the components of the guide are designed in such a way that they describe the circular movement of the front longitudinal swing arm (2).

Fig. 1 and 3 show the vehicle in driving condition. Due to the load caused by the vehicle's own weight and the possible payload, the guide elements (9) engage in the longitudinal beam, loading area/structure (7). The bushing and the guide piece of the additional guide (6) also engage with each other. When the vehicle is moving forward, the additional guide (6) is able to absorb the lateral wheel guidance forces that are transferred to the front longitudinal swing arm (2). The fork head design (5) of the front longitudinal swing arm (2) according to Fig. 2 and the additional guide (6) ensure that the front longitudinal swing arm (2) is guided stably to give the vehicle good driving characteristics.

Preferably, the inclined lift truck is lifted using a lifting mechanism (not shown) in the area of the cylinder device (1). When the wheels are not under load, the cylinder device widens the vehicle track. Furthermore, the additional guide (6) is separated when raised. The bushing and guide piece are no longer engaged.

With an increased track width, the loading area/body can be placed on the ground with the rear/lower edge. In this state, the payload can be driven or pulled onto or off the loading area. The vehicle's driving state is reached again in the reverse order. All guide elements on the longitudinal swing arms automatically re-engage.
