ABSTRACT:
A mobile lifting apparatus, such as a fork truck or a fork lift, comprises a fork carriage vertically displaceable along guides in a mast, the fork carriage comprising two parallel, horizontal transverse girders. The two transverse girders guide and support two L-shaped forks, each transverse girder having a roller bracket with rollers at the top and bottom end of its body, the roller brackets rolling on the top and bottom transverse girder. The forks are displaceable on the transverse girders by corresponding hydraulic cylinders connected between the fork in question and the fork carriage. At least one of the transverse girders is a substantially U-shaped section bar, and at least one cylinder, preferably both cylinder, is arranged in substantially the recess of the section bar. As a result the hydraulic cylinders do not impede the view of the driver onto the operating area of the forks. At the same time the cylinders are more protected against external influences, such as shocks and impacts from the load on the forks.
