Telphers by Strachan & Henshaw, Ltd. (figure).—With these telphers the whole of the load is carried on four manganese steel wheels, which are built in pairs into swivelling bogie trucks, the trucks being each pivoted independently into the main hoisting frame by universal joints. These universal pivot joints are practically frictionless, and do not depend for strength upon any pin connection. The load is directly supported solely by heavy mild steel interlocked stirrups, which have ample freedom and flexibility. The result is that all twisting strains liable to be set up, and due to the surging of the load, or sharply negotiating the curve in the track, are entirely eliminated from the main frame and bogies, and from the swivel connections between them. The four travelling wheel axles are mounted in roller bearings which are built on to the two steel bogie trucks. The telpher shown in the figure is generally adopted for gasworks duty.This machine has been developed more particularly for the purpose of handling coke, hot or cold, from all types of gas retorts—horizontal, inclined, or vertical—and has been successfully applied for this purpose in many gasworks.
