ABSTRACT:
The present invention relates to a cargo transfer apparatus of load-shifting type. The load-shifting type cargo transfer apparatus according to the present invention consists of a stationary unit and a mobile unit. The stationary unit comprises a series of equally spaced parallel projections of equal width and height. The mobile unit comprises a main frame of a hollow square section with a rectangular top, and a support equipped with a plurality of tines integrally attached like comb-teeth at equal intervals perpendicularly to the longitudinal direction of said main frame, the tines having a H-shaped cross section and having rotatable rollers fitted to a plurality of shafts fixed at both ends to both ends of the underside of the tine at the same height. A cargo holder covers the top and both side surfaces of the tines in their longitudinal direction and has elliptical guide holes to engage a plurality of knock-pins provided at equal heights on the upper sides of tines. A flexible hose is sandwiched between the tine and the cargo holder, the flexible hose being connected through pressure ducts to the supply and exhaust mechanisms for a working fluid such as pressurized oil or compressed air.
