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. Roller bearings are corrosion resistant and do not require lubrication.
