Hoisting system illustrations

With a hoisting system, there needs to be a loading pocket to feed the skips. The installation includes a pair of loading flasks fed by a single chute with a vibratory feeder to properly load the belt. The chute is equipped with an in-line chute that includes a chain gate to help meter the flow of material and an arc gate to shut off the flow entirely. The chute loads a vibratory feeder that loads the conveyor evenly to a flask to provide a metered amount of material to the skips. This portion of the system is illustrated in Figure 3.

The lift and load capacity of hoist and belt conveyor systems depend on the strength and weight properties of the hoist ropes and conveyor belts. This paper presents an analysis of the cmrent limits of appHcation of steel wire ropes and steel cord conveyor belts for haulage in imderground mass mining operations. These limits of application are illustrated with reference to a beyond super haulcige system duty of 2000 m 60 Mt/a, i.e., 10000 t/h 6000 h/a. 

So with these restrictions and developments in mind, what is the impact of all of these efforts on current design and selection efforts for hoisting plants and associated systems Table 1 illustrates a simple guideline that may be used by a prospective designer in reviewing any project that may be under consideration.
