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.
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).
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.
The PowerSeat is designed to stay in an upright position, conserving operator energy.
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.
The Harken Industrial PowerSeat is CE certified to the Machinery Directive and independently verified by Bureau Veritas.
The PowerSeat is ideal for a wide range of applications, including:

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, high angle rescue (when attached to an appropriate anchor), or in conjunction with a tripod for confined space/winching operations.
Q: Is the PowerSeat only rated for single person use?
A: Although ideal for one person, the Gas PowerSeat can also 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 stop 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 type of fuel does the Gas PowerSeat use?
A: The gas PowerSeat runs on unleaded gasoline with a pump octane rating of 86 or higher.
Q: How long does the fuel last in the Gas PowerSeat?
A: A full tank of fuel (0.6 L) allows approximately 1200 m (3937') climb distance at 273 kg (600 lb).
Q: What is the accent speed?
A: Rate of climb is 15 m per minute at 120 kg (42.2 ft per minute at 265.6 lb). 11 m (36.09 ft) per minute at 273 kg (600 lbs).
Q: What training is required? Can anyone use the PowerSeat?
A: Use of the PowerSeat must meet the regulations of the nation and industry in which it is used. It is restricted to those certified for temporary work at height with access and positioning systems using ropes.
This is not PPE equipment: Use in conjunction with a full fall arrest system at all times.
