The unit is operated using a fail-safe dead man’s switch to control ascent speed, up to 15 m/min (49.2 ft/min).
The braking system controls descent and provides workers protection against free-falls. The encapsulating jaw cover protects fingers and clothing from catching in the winch.
Stainless steel load-carrying gears and pins provide strength and durability. Sealed gearbox and high-load roller bearings reduce friction under load, are corrosion resistant, and do not require lubrication.
The PowerSeat is designed to stay in an upright position, conserving operator energy.
