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.

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.
