When emergency evacuation or escape from heights is required, then this can be achieved with ease using an Automatic Descender.
Once attached to the unit, a person can descend to the ground safely without having the concern of having to operate the equipment. These devices are extremely useful when dealing with a number of untrained or inexperienced people as knowledge of how the equipment works is not required.
Once the unit is set up on the required certified anchor or attachment point, it is then a simple matter of attaching the hook to a descending or full body harness and then the device controls the descent speed of the user to a lower level.
The descent speed is 0.8m per second which is slower than jumping from a chair. The automatic descenders come with either 15m, 30m or 60m of rope, but can be supplied with rope lengths to suit the customer.
The unit has hooks on both ends of the rope and can be used in either direction. When multiple escapes need to be made this means that as one person is descending the second hook is coming up to the top level to be used by the next person.
The Automatic Descender can also come with a rewind handle and be used to raise a person. This is extremely valuable when a person has fallen over an edge and needs to be recovered quickly.
The equipment is set up above the suspended person and the hook is lowered to them for attachment to the front rescue loops of a full body harness. The rescuer then winds the handle and raises the suspended person far enough to release the load on the fall arrest lanyard.
Once the suspended person has been released the rescuer can then automatically lower the fallen person to the ground.
This means that the rescuer is placed in very little danger.
