Abstract
The invention is a motorized winch which can be retrofitted into existing manually operated systems that use counterbalancing weights. The counterbalancing weight will be fixed at 50% of the maximum capacity of the set. The winch is rated at 50% of the maximum capacity of the set. By using the winch in a closed loop configuration, it will operate the set at any load from 0 to 100% of its rated capacity, without the need to ever adjust the counterbalancing weights.
