Abstract

924,053. Fork-lift trucks. COVENTRY CLIMAX ENGINES Ltd. Dec. 11, 1961 [Jan. 2, 1961], No. 76/61. Class 78 (3). The mast assembly of a fork lift truck comprises a primary mast, consisting of four double-I beams 8 braced together by struts 9 and mounted on the truck frame, and a secondary mast, consisting of four double-I beams 11 connected by struts 12 and slidable on the primary mast, there being rollers, Fig. 3 (not shown), provided between the corresponding pairs of beams 8, 11. The lifting carriage 14 is provided with rollers, which engage in the outer channels of the adjacent guide beams 11, and is movable vertically on the secondary mast by an hydraulic ram 18, the piston-rod of which is provided with pulleys 23, 24 which engage a chain 21 passing from the carriage 14 to a crossmember 20 of the primary mast. As the ram 18 is extended, the carriage 14 is raised on the secondary mast until a plate 22 on the pistonrod engages stops 29, 30 on the secondary mast, whereupon further extension of the ram raises the secondary mast on the primary mast. The plate 22 on the piston-rod is provided with an aperture, through which the chain 21 passes, and with a pair of apertures through which guide rails 25, 26, secured to the secondary mast, pass. In a modification (not shown), the lifting carriage may be provided with a reach mechanism supporting a pair of loadengaging jaws.
