The Harken Industrial™ Power Hauler (PWRS-G.COMPACT, PWRS-E.COMPACT, PWRS-B.COMPACT) is CE certified under the 2006/42/EC Machinery Directive and independently verified by Bureau Veritas.
The unit is operated using a fail-safe dead man’s switch to control ascent speed, up to 14 m/min (46 ft/min).
Automatic Cut-out
The Compact Battery PowerSeat has a thermal cut-out system within the motor to cut power to the seat when the working load is exceeded.
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.
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.
Battery
The Battery PowerSeat has a 50.4V lithium-ion battery with BMS (Battery Management System) to preserve its useful life. Certified to IP54. Battery life (in optimum conditions) allows for approximately 550 m (1804 ft) of travel with a 125 kg (276 lb) load.
