Abstract
1,183,676. Lift trucks. CASCADE CORP. 19 Feb., 1968 [20 Oct., 1967], No. 8041/68. Heading B8H. [Also in Division Fl] The upright pusher member 14 of a lift truck is displaced parallel to the truck frame 12 by a pair of double acting rams 38, 40 (Fig. 2) so connected that captive hydraulic fluid expelled from one side of one ram passed through a transfer conduit 106 to one side of the other ram whereby they move in unison. The rams 38, 40 are pivoted at 42, 52 to the frame 12 and their rods cause rotation of respective levers 50, 56 fixed to tubes 22, 27 carrying crossed levers 16a, 18a which act through pivoted arms 16b, 18b to cause displacement of the member 14. A changeover valve 102 directs fluid from a pump 110 to one or other of conduits 104, 108, the conduit not pressurized being connected to a reservoir 112. A filling valve 120 is provided. During normal operation valves 86, 64 in ram pistons 58, 80 remain closed, but in the event of expansion or contraction of the captive fluid they open to relieve or replenish the captive fluid.
