Speed Control

The unit is operated using a fail-safe dead man’s switch to control ascent speed, up to 14 m/min (46 ft/min).

Brake

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.

Durability

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.

Ergonomic Design

The PowerSeat is designed to stay in an upright position, conserving worker energy.

Battery
