FIELD: machine building.
SUBSTANCE: present invention relates to a ballasting means for mounting on the rear of a crane superstructure, in particular a crawler crane. Crane has a base plate and a plurality of stackable ballast plates. At least two carrier plates for receiving the stacked ballast plates are hinged to the base plate. Crane comprises a common actuator for synchronously driving at least two carrier plates. Actuator is mechanically connected by means of a coupling and/or gear mechanism to at least one, preferably with both rotatable carrier plates.
EFFECT: simplifies the design of the ballast device.
