Abstract The present invention relates to a load-shifting type cargo moving device for transferring cargo between the cargo-handling site and the element of transport such as a truck or between transport vessels like containers at transshipping points, which makes it possible to finish the job with less manpower more easily in a shorter time than by the conventional method and to carry out the transporting of palletized cargo with great ease. The present invention consists of a frame which is composed of specified parallel spaces defined by a plurality of parallel projections and of conveyors which are so disposed in every other one of said spaces so as to be able to rotate along said spaces. The arrangement is such that said conveyors can be driven by the same drive shaft to run in the same direction at the same speed. The belt top of each conveyor is located higher than the top of said projection surface. The spaces where there is no conveyor are adapted to structurally receive the tines of forklift; and when said forklift tines are so received in the spaces with no conveyor, the top of the conveyor belt is located below the top of such tines. Transfer of cargo between said conveyor belt and said forklift takes place on a load-shifting principle. Namely, the forklift tines go into the vacant frame spaces and by a vertical displacement of the forklift, the load carried on the tines can be shifted onto the conveyor belt or the other way around. The cargo, the bulk of which has been shifted onto the belt conveyor, is individually transferred to a specified position on a transport element to be fixed there. In this manner, a load-shifting type cargo moving device of this present invention can be installed on a transport means such as a truck or transport vessel such as a container and when employed in conjunction with a forklift at the cargo handling site, cargo transfer can take place easily in a brief time with use of minimum manpower.
A load-shifting type cargo moving device for use in conjuntion with a forklift, comprising a frame with a base on which are formed specified parallel spaces defined by a plurality of parallel projections with a plurality of conveyor means which are installed longitudinally in every other one of said spaces and is adapted for movement therein, said conveyor means being driven and operating in the same direction at the same speed by a common drive shaft with a belt on said conveyor means located at a position higher than the upper extremity of said frame, whErein the said spaces which are free of said conveyor means are for simultaneous introduction of forklift tines such that when said tines are so introduced into the said spaces, the top side of said belt is located above the upper extremity of said tines and wherein a plurality of free rollers are arranged at definite intervals in such manner that said rollers bear against the underside of the upper part of the belt stretched between a drive belt pulley and a driven belt pulley of the conveyor means and a plurality of bosses are formed on the peripheries of the drive belt pulley and the driven belt pulley of the conveyor means, a plurality of through holes matching said bosses are bored on the belt, and in the process of the conveyor means being driven by the drive belt pulley, said bosses successively enter and exit said through holes and, wherein a belt-tightness adjuster means is provided which contacts the underside of the lower part of the belt and is comprised of a tensioning wheel rotatably mounted on support arms resting on the base.
