<p>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.</p> |
