  • SELF-ARRESTING ROPE BELAY DEVICE
    Publication number: 20110073417
    Abstract: 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.

  • APPARATUS FOR SECURING RESCUE OPERATIONS BY HELIHOISTING
    Publication number: 20110042984
    Abstract: The invention relates to an apparatus for securing rescue operations by helihoisting that comprises three attachment means to the helicopter, the lifeguard and the belay tether. A trigger control mechanism includes a mobile pawl pivotally mounted on the hook between a closing position and a release position of the opening, respectively for maintaining the tether in the hook and for releasing the same, and a latch submitted to the action of a polarization spring for locking said pawl in the closed position in the absence of a tension on the first attachment means, and for unlocking said pawl when the force applied on the first attachment means exceeds that of the polarization spring. The assembly is arranged for triggering the automatic release of the belay tether that remained attached when the tensioning by the helicopter traction cable exceeds a predetermined threshold.
