In a crane, an arm (3) (movable in a vertical plane) is fitted on a crane housing (2), and from a winch (4) a load line (7) runs over deflecting points (12,13) on the arm and the housing. The second deflecting point on the housing is movably installed by a holder (14) so that the distance between it and the housing can be varied as a function of the tractive force on the load line. This compensates the lifting movement during load handling.(1) |
