Abstract: A crane, in particular a vehicle crane, comprising a first crane arm and at least one second crane arm which are connected together by way of a joint and which are pivotable relative to each other by way of a drive having a piston-cylinder unit, in each case starting from one of the two end positions in which the crane arms are in substantially mutually parallel relationship until reaching a dead point when the longitudinal axis of the piston-cylinder unit is substantially on a line with the joint, wherein there is provided at least one further drive by which it is possible to go beyond the dead point position of the piston-cylinder unit relative to the joint.

Abstract: A pivot joint arrangement is provided for a crane arm having a securing device for operating devices. The arrangement has a pivot joint which has two spaced-apart pivot bearings, at least one of the two pivot bearings having at least two flaps and a bearing pin. One flap is connectable to the crane arm and the other flap is connectable to the securing device, and the bearing pin is connected in a rotationally secure manner to one of the two flaps and rotates relative to the other of the two flaps. At least one swing brake brakes or damps an oscillation of the operating device on the crane arm, the swing brake having a plurality of disc-like brake elements.
