ABSTRACT:
A load handling apparatus includes a vehicle, a pair of mounting frames each hingedly mounting a pedestal for movement from an inoperative position, in which the pedestals are folded down horizontally about hinges so as to lie lengthwise of the vehicle, to an operative upright position. Each pedestal mounts a respective transverse foldable track which in use extends horizontally and on which a respective carriage is movable. Each carriage mounts a vertical telescopic mast with a head and chains, such that telescopic operation of the masts raises or lowers top lift beams for handling a load. The apparatus includes laterally movable jacks for use as stabilizers. In the inoperative position with the pedestals, tracks and masts folded down horizontally and lengthwise, the vehicle is of compact height and width.
