Abstract

The invention concerns a device in foot-operated or manually operated hydraulic stackers, pallet trucks and similar lifting tools. The device includes a hydraulic lifting piston-and-cylinder unit (2) and a piston rod (3) which is attached to a pumping lever (6) via a transverse bolt (4) for the purpose of performing pumping movements with a view to elevating a load disposed on the lifting tool. The pumping lever (6) is pivotally mounted for pivotal movement about a pivot pin (14) which extends in parallel with the transverse bolt (4). The pivot pin (14) is displaceable in a direction towards or away from the transverse bolt (4) in order to respectively reduce or increase the moment of pivotal movement.
