Abstract

The present invention discloses a new descending device based on a common rope friction device, such as figure eight for example, the speed of the rope is automatically controlled at the feeding side of the descending device with a rope speed controller 8. The angle between the rope and the rope friction descender is automatically changed by a rope angle controller 9 to generate the adequate friction that maintains the desired rope speed.
