摘要

The stacker (1) has a lifting frame (11) with weight-carrying forks (13) and a self-lifting unit (2) to lift and lower the stacker between a load support surface (F) and a driving surface. The self-lifting unit has a pivoting lifting arm (3), which lifts or lowers the stacker about a hinge point (6) arranged on the load support surface, where the hinge point remains stationary during the lift or lowering movement.
