ABSTRACT:
The present invention refers to a lifting and steering system for a vehicle. The system comprises a hydraulic system having a piston with a rod in the form of another inner cylinder, the lower end of which serves for mounting a steerable wheel of the vehicle. Another rod projects through the upper end of the hydraulic cylinder and its lower end projects through the piston to the interior of the inner cylinder. A guide member is provided for permitting relative axial movement between the piston and the second mentioned rod while causing rotation therebetween. Passages are also provided to permit the introduction and withdrawal of hydraulic fluid from the space above the piston, to the space within the interior of the inner cylinder.
