ELECTRICALLY NON-CONDUCTIVE CALIBRATED MECHANICAL WINCH AND METHOD OF MANUFACTURE

摘要

In one aspect, the present invention relates to a mechanical winch. The mechanical winch includes a body and a spool axle. The spool axle is slidably disposed within the body and coupled to the body by at least one spring. A spool is disposed about the spool axle. A non-electrically-conductive tether is coupled to the spool. A brake axle is slidably disposed within the frame and located a fixed distance from the spool axle. Actuation of the spool applies increasing tension to non-electrically-conductive tether and causes compression of the at least one spring.

主权项

1. A mechanical winch comprising:
a body; a spool rotatably coupled to the body, the spool comprising a ratchet wheel coupled to the spool; a tether secured around the spool; a handle pivotably coupled to the body and operable to impart force to the ratchet wheel so as to induce rotation of the spool; a cylinder coupled to the body; a piston disposed within the cylinder; and a spring disposed within the cylinder and operatively engaged with the piston.
