| Title: |
Compact Drive For a Counterweight Assisted Winch |
| Abstract: |
The invention is a compact drive for a counterweight-assisted winch which
can be retrofitted into existing manually operated systems that use
counterbalancing weights. The counterbalancing weight will be fixed at a
first predetermined percentage of the maximum capacity of the set,
preferably about 50%. The winch is rated at a second predetermined
percentage of the maximum capacity of the set, preferably about 50%.
Together the first and second predetermined percentages sum to at least
100% 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
the set's rated capacity, without the need to adjust the counterbalancing
weights. The compact drive system employs two motorized winches
positioned along the long axis of two adjacent counterweight rigging
systems, each winch engaging a respective chain used to move a
counterbalancing weight.
