Harken Gas PowerSeat Ascender

The Harken Gas PowerSeat Ascender has revolutionized working at height, providing the worker with the ability to ascend quickly, stay in position longer, and work in comfort. The PowerSeat provides quality, convenience, safety, and is the best solution for completing a task on hand. Fuel consumption varies with weight and usage, but the motor is extremely efficient and only uses a few gallons of unleaded gas with four-stroke mix for a full day’s work at height. The PowerSeat is simple to use and ideal for 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. The Gas PowerSeat Ascender is available in both standard and compact sizes.

The compact version maximizes the efficiency of the PowerSeat as a hauling device, while maintaining their functionality as a powered ascender. The seat has been removed and the long stem shortened for a significant reduction in weight and size. The user is suspended under the compact unit with full control from below.


  • Speed Control: The unit is operated using a fail-safe dead man’s switch to control ascent speed, up to 49.2 ft/min (15 m/min).
  • 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.
  • Automatic cut-out: The Gas PowerSeat engine is tuned to stall when the working load is exceeded.
  • 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.
  • Certification: The Harken PowerSeat is CE certified to the Machinery Directive and independently verified by Bureau Veritas.
