Abstract

A load-bearing support is provided for an industrial truck, which can be fastened to another device. At least one load-bearing means can be displaced horizontally in relation to the industrial truck and can be fastened in such a way that the load-bearing support can be tilted in vertical direction, wherein the area through which the driver of the industrial truck can see at a corresponding lifting height of a lifting carriage is maximized The load-bearing support has a rear and a front part, wherein the front part of the load-bearing support has at least one upper holder and a lower holder for the at least one load-bearing means and the two parts are connected to each other in such a way that the two parts can be rotated and laterally displaced.

Claims

1. A load-bearing support for an industrial truck, wherein at least one load-bearing means can be fastened to the load-bearing support and is designed in such a way that, by means of at least one cylinder, which is arranged in a cylinder housing and has a displaceably supported piston rod, the at least one load-bearing means can be displaced horizontally in relation to the industrial truck and can be tiled in vertical direction, and wherein the load-bearing support has a rear part and a front part, wherein the front part of the load-bearing support has at least one upper holder and a lower holder for the at least one load-bearing means and the two parts are connected to one another in a rotatable and laterally displaceable manner, wherein the rear part of the load-bearing support has at least two vertically arranged mast jaws,

characterized in

that the cylinder housing is connected horizontally to the at least two mast jaws or connecting elements, respectively, in the upper region of the load-bearing support, and the upper holder of the load-bearing support encompasses significantly more than half of the cylinder housing in a rotatable and shiftable manner.

2. The load-bearing support according to claim 1,

characterized in

that the upper holder of the load-bearing support has a rectangular outer contour and a substantially round inner contour.

3. The load-bearing support according to claim 1,

characterized in

that the upper holder has a longitudinal slit, which extends substantially across the entire width of the side of the upper holder, which points towards the rear part of the load-bearing support, in substantially horizontal direction.

4. The load-bearing support according to claim 1,

characterized in

that the cylinder housing is connected to the two mast jaws or connecting elements via an intermediate bar, and the intermediate bar is arranged downstream from the cylinder housing.

5. The load-bearing support according to claim 1,

characterized in

that two single-acting piston rods are arranged in the cylinder housing.

6. The load-bearing support according to claim 5,

characterized in

that the piston rods for the lateral displacement act directly against end elements on the outer sides of the load-bearing support.

7. The load-bearing support according to claim 5,

characterized in

that the piston rods are held completely in the load-bearing support.

8. The load-bearing support according to claim 1,

characterized in

that all horizontal positions of the load-bearing support, which can be assumed, can be fixed by means of the cylinder housing with its piston rods.

9. The load-bearing support according to claim 1,

characterized in

that the piston rods for the lateral movement of the load-bearing support are arranged on the axis of rotation of the vertical movement.

10. The load-bearing support according to claim 1,

characterized in

that the cylinder housing acts as sliding guide for the vertical rotational movement of the load-bearing support.

11. The load-bearing support according to claim 10,

characterized in

that a changeable wear bushing is introduced between the cylinder housing and the inner side of the upper holder of the load-bearing support.

12. The load-bearing support according to claim 1,

characterized in

that hydraulic connections for supplying the cylinder with hydraulic liquid are arranged on the side of the cylinder housing facing the rear part of the load-bearing support.

13. The load-bearing support according to claim 1,

characterized in

that the upper holder and the lower holder of the load-bearing support are connected to one another via at least two vertical connecting elements, and the load-bearing support can be tilted vertically via at least one separate hydraulic cylinder, which acts against the lower holder.

14. The load-bearing support according to claim 1,

characterized in

that the upper holder is supported on the intermediate bar.

15. The load-bearing support according to claim 1,

characterized in

hat the lower side of the upper holder forms the connection for the vertical connecting elements.
