LOADING AND HOISTING Sample Clauses

LOADING AND HOISTING. Loading from the muck pile was undertaken by excavator onto a 25 t Volvo ADT then hauled from the bench face to a position adjacent to the kibble. A second excavator loaded the material into a kibble which was hoisted to the collar elevation (Figure 13). An A-frame headgear was used for hoisting the material from the excavation. The A-frame had four legs supporting a beam which extended 2 m beyond the edge of the pit, allowing a kibble to be lowered into and raised from the pit footwall, and then traversed away from the pit to an area where the material was dumped into a parked truck. The A-frame was supported on a competent concrete foundation, which was anchored to the footwall, thereby securing the cantilever away from the edge of the pit. 13 a) Loading of the ore into the kibble b) Tipping of the ore in the kibble into the ADT to be hoisted to surface. to be hauled to the stockpile area at the plant.
