1,031,772. Masted lift trucks; lifting forks. LANSING BAGNALL Ltd. April 5, 1963 [April 13, 1962], No. 14345/62. Heading B8H. The lifting carriage 19 of a lift truck having a telescopic mast 17, 18 is provided with an arm 24, rotatably supporting guide rails 35 for a loadsupporting carriage 40, and with an auxiliary mast 22 which supports an operator's platform and which is movable vertically relative to the carriage 19. The guide rails 35 are rotated by an hydraulic vane motor mounted within a turntable structure 25 and the carriage 40 is moved along the rails by a pair of offset oppositely-acting hydraulic rams, Fig. 7 (not shown), and a chain, which passes from an anchorage on the turntable structure, over pulleys on the ram piston rods to a second anchorage on the turntable structure and is secured at its centre to the carriage 40. The auxiliary mast 22 supporting the operator's platform 23 is guided by rollers 21, Fig. 10 (not shown), mounted on the carriage 19 and is raised and lowered relative to the carriage by hydraulic rams 111, 112, secured to a plate 110 on the mast, and chains 114 extending between anchorages 115, 117 on the carriage 19, mast 22 respectively, and passing round pulleys 116 on the piston rods 112. Fork arms 62 connected by a back plate 73, are guided for longitudinal movement on horizontally-extending members 61, which are secured to arms 60 depending from the carriage 40, by rollers 63, 64, Fig. 13 (not shown), and are extended and retracted by hydraulic rams 70.
