Abstract

658,042. Load-handling trucks. OAKLEY, J. L. D. (Weaver Manufacturing Co.). May 13, 1949, No. 12834. [Class 78 (iii)] In a load-handling truck a platform 26 is lifted relative to a truck chassis 11 by four pantograph linkages connected in pairs 16, 17, each of which is extended by an independently operated hydraulic thrustor 44, 144 whereby the ends of the platform may be raised independently to tilt the platform. The initial lift is assisted by two vertically arranged auxiliary thrustors 49, 149 hydraulically connected with thrustors 44, 144 and which operatively engage members 52, 152 on the platform until the linkages have been sufficiently extended for the main thrustors 44, 144 to lift the load unaided. The linkage 17 is guided by means of a leg 118 and a roller 135 running in a channel 136 so that its end 125 moves in a straight line perpendicular to the chassis, but end 25 of linkage 16 is free to pivot about a point 22 so enabling the platform to be tilted.
