Battery PowerSeat® Ascender
Battery PowerSeat® Ascender

Part No. PWRS-B

The Harken Industrial Battery PowerSeat unveils new possibilities in enclosed and confined space rope access and rescue.

The Battery PowerSeat quietly delivers a powerful 300 kilogram (661 lb) hoist capability with controlled sensitivity to perform the most delicate rescues, or precise maneuvering of materials and components for installation or maintenance.

Developed specifically for rope access and winching applications, it provides a lightweight, prolonged usage, powered ascender and utility winch.

The Battery PowerSeat operates comfortably in both outdoor and indoor environments where engine emissions are restricted. It provides a level of operator safety and comfort that directly increases productivity and efficiency.

Suitable for blade cleaning, confined space and indoor rope access and rescue applications.

PS Battery


The Battery PowerSeat uses a 50.4V lithium-ion battery with a BMS (Battery Management System) to preserve its useful life. Certified to IP54.

PS Speed Control

Speed Control

The unit is operated using a fail-safe dead man’s switch to control ascent speed, up to 14 m/min (46 ft/min).


PS Break


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 Ergonomical Design

Ergonomical Design

The PowerSeat is designed to stay in an upright position, conserving worker energy.

PS 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.



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

Battery life (in optimum conditions) is approximately 550 m (1804′) with a 125 kg (276 lb) load.

Simple to Operate and Ideal for:

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

IN10636 – Max rated load 106 kN
IN10639 – Max rated load 133 kN
IN11038 – Max rated load 222 kN

The Ultimate in Power-to-Weight Efficiency

SBL (strong but light) Snatch pulleys maximize the benefits of fiber rope within a safer, more ergonomic working environment. Weighing less than 25% of comparable pulleys, they make light work of rigging and deployment.

Even the largest pulley, with a breaking load of 95000 kg (210000 lbs), weighs only 22.5 kg (50 lb). The sculpted hardcoat-anodized sheaves run on high-efficiency composite bearings, reducing rope wear.

Ideal for Diverse Applications

SBL Snatch pulleys can be used for towing, mooring, pulling, and lifting across many industries.

  • Utilities
  • Commercial rigging
  • Offshore
  • Renewables
  • Commercial marine
  • Transport
  • Salvage
  • Military

Maintenance is Simple

The simple construction requires no lubrication. Simply flush with fresh water to keep your SBL Snatch pulley free rolling.

SBL design


Side-opening plates allow the pulleys to be rigged easily. The soft attachment system eliminates heavy swivels and shackles.

SBL materials


Sideplates are hardcoat-anodized, UV-stabilized 6061-T6 aluminum for maximum protection. Sheaves run smoothly and maintain efficiency at high loads using PTFE-coated ULC bearing technology.

SBL materials

Fiber Rope

Snatch pulleys are used with fiber rope up to 25 mm (1″) in diameter. Smooth surfaces and chafe-free design minimize wear.

INLH500 LokHead winch and handle
INLH500KIT  LokHead winch kit


NEW mounting plate and tripod adapter now available.

The innovative LokHead winch is a portable or fix-mounted load-lifting, personal-hoisting winch used with an unlimited length of fiber rope. The captive head allows the winch to be used safely, and keeps the rope from accidentally releasing. Perfect for fixed or temporary applications and rescue.

Simple to use and Ideal for Diverse Applications

The LokHead winch can be used anywhere a load needs to be lifted or lowered. Rigged to a tripod, it can be used for confined-space rescue operations, for load moving/hauling, and man-riding.

Maintenance is Easy

The simple construction requires no lubrication and can be flushed clean with fresh water.


Weighing just 4.2 kg (9.3 lb), the LokHead winch can be incorporated with a compatible mounting bracket into a rescue/lifting system without significantly increasing overall weight.


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.

Ergonomic with new image


Easy to rig and efficient, the LokHead makes the most of the operator’s efforts. The winch offers two gears; 15:1 for low load/high speed use and 40:1 for higher load applications.


The winch is designed for use with fiber rope 10 –12.7 mm (3/8 –1/2″) in diameter and unlimited line length.

Manual or powered


The winch can be driven manually with the provided B10AL handle. Alternatively, use a compatible power drill with the power tool adaptor to drive the winch.

The winch is also certified under EN1496 for Human Suspension and EN13157 Machinery Directive for lifting goods and equipment.
