A belay descender device for a rope comprising a cam mounted rotating on a fixed flange to perform locking of the rope when said rope is under tension, and a lever articulated on the cam to perform progressive unlocking of the rope with a geared-down effect at the beginning of unlocking travel of the lever. The operating lever comprises transmission means collaborating with a guide ramp of the flange to interrupt the mechanical link with the cam after an intermediate position of the lever has been passed resulting in freeing from said ramp outside the gearing-down area. The end of the guide ramp of the flange corresponds to the anti-panic position of the transmission means, enabling automatic locking of the cam as soon as the gearing-down area has been passed.

The carabiner comprises: a body defining an insertion slot of a rope extended by a securing area of the rope, a first clamp fitted movable between a standby position of the rope in the insertion slot and an obstruction position when the rope is in the securing area, the obstruction position being configured to prevent insertion of another rope in the securing area, a second clamp configured to allow movement of the rope from the insertion slot to the securing area and to prevent movement of the rope from the securing area to the insertion slot.

A fall arrest safety apparatus on a rope includes 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 clamp.

A safety rope blocker having a body provided with a through hole for the passage of an anchoring ring and a curved groove opening into the through hole for the passage of the safety rope through the anchoring ring, the body being able to rotate between a blocking position in which the safety rope is blocked by the anchoring ring against the body and a releasing position in which the safety rope slide in the curved groove, the groove includes a deviation element to allow, in the releasing position, the safety rope to slide in the curved groove and outside the through hole.

A fall arrest safety apparatus with blocking on a rope, comprising:

Fall arrest safety apparatus with blocking on a rope

A pulley with an unlockable clamp, comprising a rotary roller, a pivoting trigger designed to release and clamp the rope against the roller, and control means to keep the trigger in the inactive position disabling action of the clamp, wherein the control means comprise a lock fixed onto the first flange-plate and able to be actuated from a locked position to an unlocked position to enable movement of the trigger to the inactive position.

Pulley with unlockable clamp

The invention relates to a self-arresting rope belay device comprising a cam arranged to clamp the rope when the rope is under tension, and a lever arranged to act on the cam to progressively release the rope by manual action on the lever. The lever acts on the cam respectively with a geared-down effect in an initial part of its release travel, and with a direct effect in a final part of its travel. This results in the relative movement of the cam with respect to the lever being smaller in the initial part of the travel than in the final part, which enables accurate adjustment of the braking effort and of the running speed of the rope in the initial part of travel of the lever.
