Abstract
A fall arrest safety apparatus on a rope comprising a rotary roller mounted on a pivoting arm with speed detection, and a control selector of a ratchet. The latter is able to occupy a released inactive position enabling the roller to rotate in both directions of rotation in a first fall arrest operating mode, and an active position with unidirectional blocking of the roller in rotation with respect to the arm in the descending direction corresponding to a second operating mode of the apparatus as a simple ascender.
Claims6
A fall arrest safety apparatus on a rope, comprising:
- a rigid body provided with a trunking for housing the rope,
- a securing system with a rotary roller with detection of the speed of rotation, said roller being fitted on a mobile arm able to be moved between a blocking position of the rope in the event of a fall and a released position,
- comprising a control selector of a ratchet able to occupy an inactive releasing position enabling the roller to rotate in both directions of rotation in a first fall arrest operating mode, and an active position with unidirectional blocking of the roller in rotation with respect to said arm in the descending direction, corresponding to a second operating mode of the apparatus as a simple ascender.
