Abstract: An apparatus for loading and unloading a transporter vehicle by which at least half the load is loaded or unloaded at a time comprises a travelling frame which is mounted to be moved by a travel drive device along rails provided on a fixed frame. The travelling frame carries a fork support member, provided with a plurality of lifting forks, which support member can be raised and lowered with respect to the travelling frame by a vertical drive device.The fork support member has respective projections mounted at its opposite ends which are guided for vertical movement in tilting frames mounted on respective depending portions of the travelling frame. The fork support member can be tilted about an axis transverse to the guide track by actuation of a tilt drive mechanism which drives the tilting frames to pivot the projections. The fork support member can additionally be shifted transversely to the guide track by a shifting device.
