Derope Emergency Escape Descent Device
The Tractel Derope can be used for self descent or for two persons rescue. It is particularly suited to situations where vertical escape is necessary from structures such as mobile elevated work platforms, telecommunications structures, tower, gantry cranes and wind generation equipment.
- Easy to use, minimum training required
- Descent speed to 138 ft./min. (42 m/min.)
- Capable of Multi-Person rescue
- Available with hand crank winch for limited lifting
Emergency evacuation device
The derope® emergency escape/controlled descent device enables the
evacuation of one or two persons from an elevated position to a lower
level or the ground at a controlled speed of 235 ft./min. (72 m/min.).
The derope® descent device can also be used for one man or two-man rescue
operations. Victims can be lowered alone or accompanied by the rescuer
following the standard procedures for rescue applications. If obstructions
or obstacles prevent a vertical evacuation, the operation can be carried out
down a cableway or tagline positioned at an angle between 30º and 60º.
derope® T (base model)
The derope® descent device utilizes 3⁄8 in. (9.5 mm) Kernmantle® rope
that runs through a guarded rope sheave which is connected to a sealed
centrifugal brake that limits the descent speed to 235 ft./min. (72 m/
min.). Snap hooks located at each end of the rope allow for multiple
evacuations as the brake controls the descent speed in either direction.
Dual descent pig tails and an intergraded jamming cleat give the user
more control during a rescue. External cooling fins ensure that the unit is
rapidly ready for consecutive descents.
derope® Up A descent device with hand wheel winch
Model incorporates a hand wheel winch mounted on to the base unit
which allows the Derope® descent device to be used as a lifting device.
With a lift ratio of roughly 2:1, the winch is capable of lifting a victim in
order to release it from its fall protection sub-system.
derope® Up E descent device with ladder bracket
Model equipped with a wheel winch and a ladder bracket that can be
secured on ladder rungs for more stability during rescue operations.
derope® Up R descent device with tripod bracket
Model equipped with a wheel winch and a tripod bracket that can be secured
on a tripod leg to perform rescue operations in confined space environments.
