Power Drive Unit, 2 Way

The USGS Power Drive Unit has a 12 VDC electric motor equipped with dual V-belt pulleys for use with B-56 reels converted for power drive, and all E-53 reels. The DC motor is a heavy-duty, high-inertia starting motor. Also included is a trigger switch, a trunk, two V-belts, connecting battery cables, and a mounting bracket for cranes. The unit is designed for mounting on a Type A or Type E bridge crane on the vertical angles beneath the reel mounting plate. Also, it is designed to be mounted on the boat boom.

Standard USGS cable cars must be modified to attach the power drive unit. Cable car modification kit details can be found with the cable cars. A heavy-duty 12-volt battery can normally be used from a vehicle, but one can be supplied if necessary.

This power Drive Unit is considered a Power Up-Power Down device meaning the power unit provides power for lifting AND lowering the weight.
