CABLE REEL STRING INSTALLATION

摘要

A cable stored on a reel can be reeled out to any adjusted length within its limit. Control mechanism allows locking the drum for load transfer between the cable and the reel at any adjusted position. A load indicating system is supplied to show when a predetermined load is applied at the loaded end of the cable. For this purpose a pair of electrical conductors extend through the cable and a continuing circuit is supplied from the outer rim of the rotating drum to the stationary reel housing. A clock type spiral spring is supplied to rewind the cable and this spring is split into a plurality of sections which are supported in insulated relationship to the drum and housing. In this way the spring parts are used as conductors in the electrical circuit with suitable connections at the outer end spring attachment and at the inner end spring attachment.
