Abstract (en)
[origin: EP0386632A2] A crane is described on which an operating mode can be set in which the sliding arm (1) is braked by the rope winch (2) when the sliding arm (1) is extended but the rope winch (2) is braked by the sliding arm (1) when the sliding arm (1) is retracted, in the course of which a pressure-relief valve (10 or 11) in the hydraulic circuit of the sliding arm (1) or the rope winch (2) in each case limits the tension in the rope (3). <IMAGE>
