Suitable for blade cleaning, confined space and indoor rope access and rescue applications.

PS Battery

Battery

The Battery PowerSeat uses a 50.4V lithium-ion battery with a BMS (Battery Management System) to preserve its useful life. Certified to IP54.

PS Speed Control

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).

 

PS Break

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.

PS Ergonomical Design

Ergonomical Design

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

PS Durability

 

Durability

Stainless steel load-carrying gears and pins provide strength and durability. Sealed gearbox and high-load ball bearings reduce friction under load, are corrosion resistant, and do not require lubrication.

PS CE
