TRACK-RELAYING EQUIPMENT

A number of Secmafer Boyer Schwarz M.6 track-relaying gantries have been supplied to British Railways. Each gantry weighs 7-1/2 tons, and the overall width is 11 feet 4 in., with 9 feet 6 in. inside clearance for lifting the load. With the twin rams and screw-jacks mounted in the side frames both fully extended a pair, or one unit, of gantries can load or unload up to four concrete-sleepered sections high on a standard Salmon wagon, with 2-in. of timber packing on the wagon deck. Power is supplied by a standard Renault Dauphine engine. The machines have operated successfully on an incline of 1 in 40. The speed of lift of the twin rams is 22 ft. per min., and of the screw jacks is 12-8 ft. per min. when the two movements are made simulatneously, these speeds are approximately halved.
