ABSTRACT:
The invention relates to a descent control unit of the kind used for lowering an injured person on a rope. The unit consists essentially of bar around which the rope is wound and a gate arrangement which is hinged to one end of the bar and is detachably secured to the other end of the bar by a locking pin. The bar and gate thus combine to form, in use, a closed loop through which the rope passes. The gate arrangement is formed so as to have a hook which extends beyond the other end of the bar to facilitate a lifting operation using the free end of the rope and a groove is provided in the gate arrangement to guide the free end and facilitate control of the descent rate. A snap hook on the gate provides for connection of the unit to a harness on the injured person and the snap hook is provided with an arm which extends across the groove to retain the rope therein when the unit is under load.
