ABSTRACT:
A cable foul sensor device for winches includes a flapper plate extending from a cover for the cable drum, and a sensing finger extending along the edge of the flapper plate to terminate above an upper layer of cable wound on the drum. The flapper plate is connected to a pivot member through which an adjustable set screw is mounted. A stationary housing for spring loaded switches is mounted on the cover and includes a contact plate which is depressed downward by the set screw of the pivot member to force the switches to the closed position to provide power for the drum. Upon fouling of the cable at the drum, the cable foul will displace the sensing finger and the flapper plate which will cause the pivot member to pivot away from the actuator plate, thereby permitting the spring loaded switches to bias in the open position to interrupt power to and lock the drum. An audio and/or visual signal is provided to indicate that a cable foul at the drum has occurred.
