What is probably the most advanced 75 ton capacity railway breakdown crane in the world is now under evaluation by British Rail at Doncaster. This attractive diesel-hydraulic powered design is the first, and perhaps the most striking, of a new range of rail cranes from the Cowans Sheldon works in Carlisle. The revolving superstructure is carried on a four-axle carriage which incorporates a specially developed suspension system to give the correct ride index for high speed rail travel and provision for lateral axle adjustment to allow the negotiation of severe curves. The two-element jib is fabricated from high-tensile low alloy steel, quenched and tempered, with the telescopic section sliding on pads faced with special wear-resistant material. Power for the telescoping motion is provided by twin double-acting hydraulic cylinders located inside the jib, and the derricking motion is powered by twin double-acting cylinders connected between the underside of the jib and the top plate of the revolving superstructure. Self-propulsion of the crane is by a hydrostatic drive via transmission gearboxes on the two outermost axles driven by fixed displacement motors supplied by variable displacement pumps.
