Abstract
The utility model relates to the technical field of goods lifting and conveying devices, in particular to a four-wheel drive forklift truck suitable for loading and unloading goods in a container. The four-wheel drive forklift truck comprises a front frame and a rear frame, wherein the front frame and the rear frame are hinged together. A torque converter is arranged on the rear frame, and a cab and a fork lifting device are arranged on the front frame. The fork lifting device comprises multiple levels of portals which are arranged in parallel from outside to inside and capable of sliding relatively. The portals include the outer portal located on the outer side and the inner portal located on the innermost side. The section of a stand column of the outer portal is in a C shape, and the sections of a stand column of the inner portal and stand columns of the rest portals are in L shapes. The radius of turning circle of the four-wheel drive forklift truck is reduced with the center hinged type structure of the whole four-wheel drive forklift truck; the manner for arranging the torque converter and the cab reduces the height of the whole four-wheel drive forklift truck to the maximum; the multiple levels of portals which are matched in C and L shapes are arranged in parallel, and therefore a lifting arm of force for forking goods with fork teeth is effectively shortened; with the free lifting device, the lifting height of the four-wheel drive forklift truck can be below 2m, only the fork is lifted and the portals are not lifted. The four-wheel drive forklift truck can flexibly enter and exit the container to perform loading and unloading work.
