Abstract: 1475578 Elevating apparatus RAYMOND CORP 8 Aug 1974 [20 Feb 1974] 34940/74 Heading B8L The mast 15 of a lift truck 10 is tiltable by a ram 30 and at its lower end is mounted between a pair of forwardly extending housings of the truck, the mounting arrangement facilitating movement of the mast between any one of a plurality of discrete positions forwardly of a main frame from which the housings extend. Each housing, which includes a gear transmission (see Division B7) between a motive means on the main frame and a drive wheel 11 at the forward end of the housing, is provided with reference surfaces to which is secured a block apertured at intervals to pivotally receive a stub shaft at one side of the mast. The mast stub shafts are selectively received in any coaxial pair of apertures in the opposed blocks depending on the centre of gravity of the load being handled and the fitting on the lifting carriage of the mast, the two ends of each block being different distances from the adjacent apertures so that by reversing the blocks on the housings a different set of positions for the apertures relative to the housings is achieved. In one embodiment Fig. 4a (not shown) each apertured block is split along the aligned diameters of the apertures so that the top half of the block can be unbolted and removed to permit insertion or removal of stub shafts fixed to the mast.  In the embodiment of Fig. 6a (not shown) the stub shafts are formed as a single telescopic shaft extendable to pass through journals in the mast for register with the apertured blocks which do not need to be split.
