摘要

A cable drum receives a length of working cable that is wound in and out from the drum in response to powered rotation of the drum with an uppermost layer of working cable on the drum forming a working surface. A torque sensor in communication with the cable drum measures a torque applied to the cable drum due to tension on the working cable from a load. A drum height gauge is provided for measuring a height of the working surface of the cable on the cable drum. A processor receives the torque value from the torque sensor and the height of the working surface from the drum height gauge and computes a force applied to the length of working cable due to the load based on the torque and height of the working surface. The work performed by the cable may be calculated to assist in determining cable health.

主权项

1. A system comprising:
a cable drum that receives a length of working cable that is wound in and out from the drum in response to powered rotation of the drum with an uppermost layer of working cable on the drum forming a working surface; a torque sensor in mechanical communication with the cable drum that measures a torque applied to the cable drum due to tension on the working cable from a load; a drum height gauge for measuring a height of the working surface of the cable on the cable drum relative to the cable drum; a processor that receives the torque from the torque sensor and the height of the working surface from the drum height gauge and computes a force applied to the length of working cable due to the load based on the torque and height of the working surface.
