Abseiling slider for building fire rescue rope - has exchangeable stationary V-groove disc adjacent lever-operated pressure roller around which rope is looped

摘要

The slider has a base plate (1) on which an exchangeable stationary disc (2) is fixed by two screws. Discs with various section V-grooves can be used with cables or ropes of different sizes and/or materials. The slider is suspended from a fixed point of the building, from which the rescuing abseiling is to take place, by a top or cable (5). The cable is led over a deviating roller (4) then over part of the circumferent of the stationary disc. The looping angle of the cable over the V-groove of the stationary disc can be varied by the pressure roller (7) manually pivoted by the user via a handle (6). To set the degree of frictional braking and thus the rate of descent.
