A bin installed adjacent to the shaft bottom in skip winding. The capacity
of the chute is equal to that of the skip used, ranging from 4 to 10 st
(3.6 to 9.1 t). Bin-feeding arrangements differ but may be by a steelplate
conveyor from a surge bunker that in turn receives the ore or coal from
the mine cars or a trunk conveyor. A measuring chute ensures a quick and
correct loading of skips without spillage. Immediately the skip is
positioned in line, the measuring chute bottom door opens and material is
discharged into the skip. See also: pocket Nelson
