Lifting frame and hydraulic cylinder with a compensation device (

摘要

The object of the invention is a lifting frame for an industrial truck with a liftable load bearing device (33) which, by extension of a piston (14) comprises a cylinder tube (2) of a lifting cylinder (34) can be raised. A with the load bearing device (33) raised load generates a bending moment acting on the lifting frame. The lifting cylinder (34) has a relative to the cylinder tube (2) movable compensating piston (7), with which a acting on the lifting frame, the bending moment a result of a counter or load moment can be generated. The compensation piston (7) is coaxial to the piston (14) of the lifting cylinder (34) arranged and provided with a passage for the piston (14) on. The compensation piston (7) is preferably provided on the outside of the cylindrical tube (2) guided.
