Abstract
972,352. Masted lift trucks. GENERAL ENGINEERING CO. A.B. Jan. 16, 1963 [Jan. 19, 1962], No.2061/63. Heading B8H. In a lift truck mast assembly comprising telescoping sections 10, 12, 14, the cylinders 20 of hydraulic rams for. raising the section 12 relative to the section 10, which is secured to the truck chassis, are integral with the side members 16 of the section 10. Tubular plungers 32 are slidable in the cylinders 20 and are secured to the side members 26 of the mast section 12 which are provided with rollers 34 engaging in guide channels 24 formed in the side members 16. Further rollers, Fig. 5 (not shown) mounted on axes perpendicular to the axes of rollers 34 engage flanges 22 of the side members 16. Cross-members 28, 68 extending between the side members 26 support a ram cylinder 38, the piston-rod 40 of which is secured to a cross-member 42.extending between the side members 44 of mast section 14 which are guided on the side members 26 by rollers 48, 50. Sprockets mounted on a crosshead 64 secured to the piston-rod 40 support chains 60 which extend between the lifting carriage 54 and the cross-member 68 of the mast section 12. On supplying pressure fluid to an inlet on the ram cylinder 38 when the mast assembly is retracted, the piston-rod 40 raises the mast section 12, thereby raising the lifting carriage 54 relative to the section 14. When the section 14 is fully raised relative to the section 12, fluid passes through duets in the section 12 and through the tubular plungers 32 into the cylinders 20, thereby raising the mast section 12, together with the mast section 14 and lifting carriage 54, relative to the fixed section 10.
