The unit is operated using a fail-safe dead man’s switch to control ascent speed, up to 14 m/min (46 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 worker energy.
The Battery PowerSeat uses a 50.4V lithium-ion battery with a BMS (Battery Management System) to preserve its useful life. Certified to IP54. Battery life (in optimum conditions) allows approximately 550 m (1804′) of travel with a 125 kg (276 lb) load.
