If a worker slips or falls, the 3-Way SRL locks up to arrest the fall. The system can then be activated into winch mode, raising or lowering the worker to safety. The 3-Way is different than the standard SRL by adding retrieval/descender capabilities. SRL's are extremely important in fall arrest/rescue & retrieval applications. When entering a confined space by ladder, fixed structure, or while being lowered mechanically by a man-rated hoist, a worker must be attached to an independent lifeline for adequate fall protection. Pelsue's SRL's meet or exceed OSHA requirements for confined space rescue.
