Abstract

A system (19; 19, 35) for reducing an amount of a counterweight for a crane comprises a crane (2) having a founding structure (3) being disposed on a base (20), a coupling unit (4), and a superstructure (5) being coupled to the founding structure (3) via the coupling unit (4). The system (19; 19, 35) further comprises a suspension device (21; 21, 36) for suspending the crane (2) at the base (20), said suspension device (21; 21, 36) having a guiding structure (22; 22, 37) defining a guiding direction (23; 23, 38), said guiding structure (22; 22, 37) being attached to the base (20), a displacement device (24) being displaceably attached to the guiding structure (22; 22, 37) along the guiding direction (23; 23, 38), and at least one suspension element (29) being connected with a first end to the crane (2) and being connected with a second end to the displacement device (24).
