ABSTRACT:
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 one jack (26, 26',29) of the multiple-stage single or double-acting type, and preferably of the hydraulic type. The fork (28) is rotated about a vertical axis in order to angularly position it with respect to the load to be handled, and is then locked in such position.
