ABSTRACT:
Tensiometer placed on the free end of an aerially articulable boom such that the tensiometer's load indicator is visible from the bucket. A cable extending from the boom's free end may be attached to a working object such as a transformer. When the boom is raised, the working object is lifted off the ground. The tension placed on the cable causes a readout on the tensiometer indicating the load on the cable. Thus, a worker in the bucket can immediately determine whether the load on the cable exceeds the allowable limits.
