A general view of Sullivan Ironclad Tubinair Machines. The appearance of electric machines is practically identical. In the upper picture the haulage chain is arranged for slewing the jib under the coal. In the lower picture the haulage chain is arranged for cutting along the face to the left (i.e. to the spectator's right). The control levers are all at the right end of the machines.
