Descenders for Technical Rescue

Descenders

• AUTO-LOCK system: automatically locks the rope

• Excellent hauling eff iciency

• Comfortable, controlled descent, even with heavy loads

• Easy rope installation

The AUTO-LOCK system

allows automatic locking

of the rope when the

handle is not in use.

Once locked, the rope

can be taken up without

having to manipulate the

handle.

The faceted sheave creates additional

friction zones for the rope, providing

extra braking for lowering heavy loads.

The ergonomic handle and integrated

brake enable a comfortably controlled

descent.

The integrated progress-capture

pulley with very large diameter sheave

mounted on sealed ball bearings rotates

in only one direction for excellent hauling

efficiency. The lower connection point

can be used to create different types

of haul systems.

Markings on the device make

rope installation quick and easy.
