Compact Gas PowerSeat® Ascender

Part No. PWRS-GC

The Compact Gas PowerSeat® ascenders are lightweight portable winches that are used as mechanical ascenders for working at height and other winching applications, including 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 Gas PowerSeat provides operators with a prolonged usage ascender which accommodates an unlimited length of rope pull.

The PowerSeat can be operated with ease and confidence, even in situations where engine emissions are not restricted, providing a level of comfort and security that directly increases operator productivity and efficiency.

Suitable for outdoor rescue and utility winching/lifting markets.

 

PS Speed Control

Speed Control
The unit is operated using a fail-safe dead man's switch to control ascent speed, up to 15 m/min (49.2 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 Compact break and frame

Automatic cut-out
The Gas PowerSeat engine is tuned to stall when the working load is exceeded.

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

Certification
The Harken PowerSeat is CE certified to the Machinery Directive and independently verified by Bureau Veritas.

Applications

The PowerSeat is ideal for use in a wide range of applications: wind turbines, building exteriors, search and rescue—not only as a powered ascender, but also as a portable winch or hauler.

Q: Is the PowerSeat just a mechanical ascender?
A: The certification of the PowerSeat allows it to be used as a powered ascender for access, as well as rigged to assist with hauling and pulling. For example, cliff rescue (when anchored to a strong point), or in conjunction with a tripod for confined space/winching operations.

Q: Is the PowerSeat only rated for single person use?
A: No, the PowerSeat can be used in tandem rescue situations to a maximum working load of 273 kg (601.9 lb).

Q: What happens if I inadvertently exceed the working load of the PowerSeat?
A: The gas PowerSeat engine is designed to stall when the working load is exceeded. The electric PowerSeat has a thermal cut-out within the transformer to cut power to the seat. In both cases, the seats are free to descend to release the load. The seats can be restarted to continue use.

Q: What is the accent speed?
A: Rate of climb is 15 m per minute at 120 kg (49.2 ft per minute at 265.6 lb), 11 m per minute at 273 kg (36.09 ft per minute at 601.9 lbs).
