the cage is normally equipped with safety devices for protection in the event of rope failure. these safety devices are designed to operate on the timber guides. 2.1.2. skips skips are shaft conveyors for hoisting orecoal or waste from the underground. the most significant feature is the method by which orecoal is discharg ed from the skip.abb has been working with the mining and minerals industry for more than years. over the past six decades we have not only improved entire plant processes, but also developed a comprehensive portfolio of mining services ranging from long-term service agreements to individual service products like spare parts, training, engineering and consulting.sep 13, 2019 this type of headgear is not used. designof headgear depends on following parameters total static loads:weight of cage, rope, pulley, guide rope, tub & mineral. rate of acceleration & retardation maximum velocity. depth of shaft diameter of shaft size of cageskip

It is therefore apparent that underground
