763,771. Fork lift trucks. SCHWEIZERISCHE INDUSTRIE-GES. Jan. 18, 1955, No. 1529/55. Class 78 (3). The fork 18 of a lift truck is pivoted to the lifting carriage about a vertical pin 21 which is mounted on the carriage for lateral sliding movement. As shown diagrammatically in Fig. 3, a member 12 is moved relative to the carriage 8 by a thruster 9, 10 and bar 11, whilst a member 13 is simultaneously moved relative to member 12 by chains 14, 15. A further thruster 20 swings the fork about pin 21. Figs. 4-6 (not shown) illustrate the preferred construction in which members, corresponding to members 12, 13, are housed coaxially within a guide secured to the carriage; and a series of rollers are provided to guide the movements of the members. The Specification states that the fork can be swung to either side of the truck. |
