FIELD: transport, package.SUBSTANCE: mine skip hoist comprises drum-type hoisting machine with steel rope secured to said drum, rope deflecting pulley, and skip fixed to rope. Said skip consists if frame and body for rock mass to be carried therein. Second hoisting machine is installed parallel with the first one, equipped with deflecting pulley with second end of said steel rope secured to second machine drum to run through 180 degrees over reverse pulley arranged to run axle at skip frame top edge. Thrusts are fixed on both rope runs nearby reverse pulley with minimum gaps relative thereto to interact therewith in the case of rope rupture at any of said runs. Grooved reverse pulley has outer edge furnished with ledges bent outward at right angle to interact with aforesaid thrusts secured at rope runs, their lower edges are rounded to radius equal to that of reverse pulley outer edge.EFFECT: higher hoisting capacity and skip reliability.4 dwg |
