25、a rescuer or lifts himself from a lower to a higher place 3.2 rescue lifting device class B rescue lifting device class A with an additional hand-operated lowering function intended for lowering a person over a distance limited to 2 m NOTE The limited lowering function is provided because in some ci

26、rcumstances it may be necessary to lower a person a short distance during a rescue lifting operation, e.g. to avoid an obstruction. For a rescue by descent, a descender device conforming to EN 341 should be used. Licensed Copy: Wang Bin, na, Mon Mar 05 01:12:56 GMT+00:00 2007, Uncontrolled Copy, (c)
