The ROTOR rescue and evacuation descender is designed for raising, lowering and evacuation, with multiple evacuee capability.

It is simple and intuitive to use, incorporating a range of operation and safety features to aid users.

The ROTOR constant rate descender has a low profile body with no external moving parts preventing the risk of snagging which could interrupt the descent.

The ROTOR rescue and evacuation descender features attachment load point indicator that shows if device has been used.

The device has push button mode selection for lifting or lowering in either direction – central neutral position for lowering, left/right position for lifting mode.

When set in lowering/evacuation mode, descent is automatic. Friction points can be used to provider additional control for lowering a casualty.

Detachable ratchet handle is used to lift in either direction. Ratchet locking mechanism holds the load if the handle is released.

Locking mechanism is engaged by simple push button, which is recessed to protect against accidental operation. ‘Free running’ position can be engaged for evacuation /descent use.

Automatically controls descent speed to between 0.7 m/s and 1.7 m/s, depending on load, without the need for manual operation.
