Abstract

The mechanism counterbalances the weight of a derricking beam, partic. on the superstructure of a travelling dredger, depending on its angle, and has a movable tailweight. Between a fixed member and the derricking beam (1) is a hydraulic emitter (3), connected by pipes of a hydraulic system to a hydraulic motor (5) moving the railweight (4). The emitter can comprise a piston with rod working in a cylinder, both of whose chambers are connected to the controller of a reversible-flow hydraulic pump. The latter supplies the chambers of a ram whose piston rod is fixed to the tailweight.
