<p>The invention refers to an apparatus for loading and unloading palletized materials (C) into and from isothermal delivery wagons (F). The apparatus comprises a powered carriage (4) which is longitudinally movable on parallel guides (1,1') secured to the upper interior portion of the wagon (F). A telescopic guiding and lifting/lowering structure connected to the underside of a powered and transversely-movable slide (17) and supporting in cantilever fashion a fork (28) for handling the palletized loads (C), comprises at least a cylinder-and-piston unit or jack (26,26',29) of the multiple-stage single or double-acting type and preferably of the hydraulic type. Means being provided to rotate the fork (28) about a vertical axis in order to angularly position the fork suitably with respect to the load to be handled, and means being provided to lock said rotation.</p> |
