ABSTRACT:
The weight of a pivotally mounted boom in a crane is compensated for in part by a counterweight which is suspended from one end of a compensating cable trained over a deflecting pulley at the top of the supporting crane structure. The other end of the cable is connected to a first fastener near the pivot axis of the boom by a rod and to another fastener on the boom remote from the pivot axis by a flexible chain. The rod is shorter than the distance between the first fastener and the deflecting pulley so that the compensating cable and the rod are longitudinally aligned before the boom reaches its steepest position, the boom thereby being relieved from the then unnecessary action of the counterweight.
