ABSTRACT:
A truck exhibiting lifting devices intended for the lifting of loads and pairs of wheels located at a certain distance from each other and adjacent to said lifting devices. At a point mid-way between the wheels making up the pair of wheels is support wheel so arranged as to absorb some of the compressive forces acting upon the pair of wheels. The support wheel is so arranged as to be forced against a base by a device consisting of a hydraulic piston and cylinder. The pressure inside the device is controlled by the pressure inside a load-lifting hydraulic piston and cylinder device.
The support wheel is pivotable or turnable in relation to the setting of the steering wheel.
