Abstract
A control system for determining a line pull of a winch. The system comprises a first sensor configured to measure a torque generated by the winch to retract a cable and a second sensor configured to measure a number of layers of the cable retracted by the winch, wherein a layer of the cable is formed by a single wrap of the cable onto a container. The system further comprises a monitoring circuit coupled to the first and second sensors, wherein the monitoring circuit is configured to determine the line pull of the winch based on the torque generated by the winch and the number of layers of cable retracted onto the container.
