| Patent Number: |

| Title: |
Counterweight Assisted Winch |
| 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.
