In a few isolated cases where the works in question and the colliery not far distant are under the same control, the fuel may be brought by a ropeway which would deliver automatically on the top of the pile, but this is so rare an occurrance that the proposition might almost be ignored. If the railway siding should be or can be brought high above the ground level, it may be possible to bring the rails right along the centre line of the main pile high up, and so deposit the coal by self-unloaders. This is an ideal solution, but unfortunately not often possible. The only other proposition is to empty the railway trucks either by tip, or by the use of self-discharging wagons, into a pit from which the coal is raised by a continuous elevator and conveyor (to be more fully described under the heading "Terminal Plant "), or by any ol the intermittent handling devices, to the top of the heap. This means a steel structure on the top of the hoppered concrete base of the stock-pile. A travelling crane running on rails with a clamshell bucket, on one or both sides of the pile, which grabs the coal out of the aforesaid pit, travels along the pile to deposit its load wherever the heap wants replenishing. With this arrangement the coal can be reclaimed either as deposited, by grab, or via the tunnels by other conveyors. One of the best intermittent conveyors for this particular purpose and not yet mentioned is the Hunt automatic railway, which can be used in connection with coal unloaded, as stated, from railway trucks, or it can be charged via a small receiving hopper from a crane and grab, as taken from a barge.
