The R-ALF kit is a 5:1 mechanical advantage system. The master pulley (the R-ALF) has a built-in overspeed brake which will automatically engage to stop the freefall within a very short distance, if the user releases the control rope. This R-ALF auto-locks in both directions, making it an easy and safe device to use for lifting and lowering people. Suitable for heavy loads up to 250kg (550Ib), R-ALF is perfect for a wide range of uses including 2 person assisted stretcher rescues, bariatric rescue, work suspension on structures and confined space working. R-ALF is also a superb multi-function device for confined spaces as it can be used in the vertical for lifting/lowering as well as in the horizontal for dragging. R-ALF can be used either by the operator for work positioning in tanks, as an access device in sewers and manholes or by a rescuer either in the confined space or at the top anchor (a tripod for example).
