Lory is a robust multi purpose device for use in industrial access and sport climbing applications. Its functionality spans the range from rope access and rescue descender device through semi-automatic belay device to rope positioning and retention device for use on rooftops and edges.
Two sub-types of the device exist: LORYsafe with unimpeded movement of the cam (for industrial use) and LORYsmart with impeded movement of the cam (also for sport use).
Cam rotation impediment aids in feeding rope to the lead climber. By pulling the working end of the rope the cam engages and jams the rope. By pulling the handle the cam gradually releases the rope.
If the handle is pulled down to its terminal position the double-stop function is triggered which blocks the rope again. To resume descending, return the handle in closed position and restart the process.
