Abstract
A linkage mounted counterweight for offsetting a load at the free end of an articulated boom crane (20). The articulated boom crane (20) includes an articulated boom (23) that includes an elevate linkage (25) and a telescoping section (24) is disclosed. The elevate linkage (25) includes a lower section (42) and a mid section (44). The counterweight (60) is located on the lower section (42) near where the lower section (42) is hingedly attached to the base of the crane (20). As the articulated boom (23) is raised from a stowed position, the counterweight moves away from the tilting fulcrum (F) of the articulated boom crane (20) to assist in maintaining the stability of the crane.
