Abstract (en)

A crane, comprising a foot provided with a turntable by means of which a crane base is rotatably supported, a front boom and a rear strut which are attached to the crane base some distance apart about parallel axes of rotation orientated transversely to the axis of rotation of the turntable, a top boom, the rear end of which is attached to the rear strut such that it can pivot about an axis of rotation parallel to the axes of rotation on the crane base, the front boom being attached to said top boom, between the rear end and the front end, such that it can pivot about an axis of rotation parallel to the axis of rotation at the rear end, balancing means which interact with at least one of the boom and strut and a hoist line suspended from the front end. The front boom and the pivot joints thereof with the top boom and the crane base are designed to transmit compressive forces and torque and the rear strut and/or at least one of the pivot joints thereof with the top boom and the crane base are designed to transmit essentially only tensile forces. <IMAGE>
