Abstract: A device to be strapped on a person for controlling descent down a cable or rope secured to an elevated structure. The device includes two endless chains of coacting teeth which intermesh in a linear channel to define a confining sinusoidal path for the cable which frictionally locks the chain to the cable. An adjustable braking mechanism controls the rate of chain travel, and thereby the rate of descent of the person wearing the escape device.

Abstract: A device, system and method are used for hoisting and lowering a load. The device has a front plate that may be displaced to reveal a sheave. The device also has a friction accessory. The friction accessory is arranged to create friction between a rope and the device when a load is suspended from the device using the rope and where the device is secured to a support structure. The system may be prepared by an operator, having ascended to an elevated location, and further allows the operator to lower the load from the elevated location prior to descending.
