Auto Descending Device

Uniform speed slow down, safe and reliable

The Auto Descending Device is an emergency escape device for altitude descent, which can be used in altitude escape and training exercises. The operator descends from a higher position along the rope at constant speed to a safe position through the escape bag.

Automatic Descent

The Auto Descending Device is an essential safety device when working at height. In cases where regular descent via the wind turbine tower’s ladder or lift is not possible, the Auto Descending Device provides emergency descent. With its bi-directional design, it enables the fully automatic, controlled evacuation of up to two people simultaneously. The dual-brake mechanism with active heat dissipation ensures reliable performance, even when descending heavy loads from great heights.

Product Details

Self-Cooling Double Brake

The dual-brake mechanism with active heat dissipation provides stable descent at uniform speed. Even heavy loads can be abseiled from tall towers, enabling simultaneous two-person evacuation.

Bi-Directional Design

The bi-directional design allows for the uninterrupted descent or rescue of several people. Both ends of the rope can be used for descent, enabling continuous abseiling. This allows for quicker rescue.

High-Performance Rope

Designed for application on- and offshore, the highly robust kernmantle rope is resistant to wear, fire, saltwater spray, and high and low temperatures.

Customizable Rope

The rope length can be customized based on usage requirements.

Key Features

1

Bi-Directional Design

The bi-directional design of the Evacuation And Rescue Device allows for the uninterrupted descent or rescue of several people. Both ends of the rope can be used for descent, enabling continuous abseiling. This allows for more people to be evacuated in a short amount of time. In addition, the intuitive design prevents human error, thus increasing safety.

4

High-Strength Aluminum Alloy

The high-strength aluminum-alloy construction of the housing is lightweight and corrosion-resistant.

5

Ball Bearing Rope Routing

The ball bearing design of the rope routing ensures maximum durability and stability.

6

Optional Accessories

A flexible anchor point, edge protector, and crow bracket are available upon request. The device kit can also be configured to include additional brackets, straps, edge protectors, t-bars, and other rescue accessories.

Packaging Options

The Evacuation And Rescue Device is available in four different packaging options.

  • Moisture-proof bag: The most convenient option for technicians who carry the device to different locations.
  • Vacuum-sealed, inside a moisture-proof bag: Perfect for cases where the device is kept in a confined space.
  • Vacuum-sealed, inside a sturdy plastic box: Ideal when the device is kept inside the turbine permanently.
  • Vacuum-sealed, inside a C4H corrosion-resistant metal box: Another popular option for units that remain inside the turbine.
