ABSTRACT:
A device for sensing the exerted load on a rope, wire, or the like, comprises two mutually aligned wheels around which the rope or wire passes and a load sensor placed between the wheels. A clamping device connected to the load sensor is clamped to the rope or wire to divert the path of the rope or wire as it passes between the wheels. The load sensor comprises a roller connected to the clamping device and a shaft pivotally mounted within the roller by means of self-aligning bearings. A plurality of transducers are mounted to the shaft and the transducers are coupled to a means for indicating the load on the rope, wire, or the like as a function of a variation in the electrical characteristics of the transducer during bending of the shaft responsive to exertion of a load on the rope, wire, or the like.
