Compact Battery PowerSeat® Ascender
Compact Battery PowerSeat® Ascender

Part No. PWRS-BC

The Compact Battery PowerSeat® ascenders are lightweight portable winches that are used as mechanical ascenders for working at height and other winching applications, including access and rescue.

These compact versions maximize the efficiency of the PowerSeat as a hauling device, while maintaining their functionality as powered ascenders. The seats have been removed and the long stem shortened for significant reductions in weight and size. The user is suspended under the compact unit with full control from below.

Developed as a requirement in industry, the Harken Industrial Battery PowerSeat provides operators with a prolonged usage ascender which accommodates an unlimited length of rope pull.

The PowerSeat can be operated comfortably and confidently in both outdoor and indoor environments where engine emissions are restricted, providing a level of operator safety and comfort that directly increases productivity and efficiency.

Suitable for blade cleaning, confined space and rescue applications.
