PWRS-B PowerSeat Battery Powered Ascender

The Harken Industrial Battery PowerSeat unveils new possibilities in enclosed and confined space rope access and rescue. The Battery PowerSeat quietly delivers a powerful 300 kilogram (661 lb) hoist capability with controlled sensitivity to perform the most delicate rescues, or precise maneuvering of materials and components for installation or maintenance. Developed specifically for rope access and winching applications, it provides a lightweight, prolonged usage, powered ascender and utility winch. The Battery PowerSeat operates comfortably in both outdoor and indoor environments where engine emissions are restricted. It provides a level of operator safety and comfort that directly increases productivity and efficiency. Battery life (in optimum conditions) allows approximately 550 m (1804') of travel with a 125 kg (276 lb) load. Suitable for blade cleaning, confined space and indoor rope access and rescue applications.

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).

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

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.

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. Battery life (in optimum conditions) allows approximately 550 m (1804′) of travel with a 125 kg (276 lb) load.
