Gas PowerSeat® Ascender
Gas PowerSeat® Ascender

Part No. PWRS-G

The Harken Industrial 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 time.

Fuel consumption varies with weight and usage, but the motor is extremely efficient and only uses a few liters of unleaded gas with 4-stroke mix for a full day’s work at height.

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

The portable unit weighs just 14 kg (31 lb), so it’s easy to carry around, yet strong, durable, and corrosion-resistant.
