装置。[Claims for Utility Model Registration] (1) The main body is formed into a hollow shape by holding a bucket at the front end which is raised upward by the operation of a hydraulic drive system including a dump cylinder, and the rear end is held by the operation of another hydraulic drive system. In an industrial vehicle equipped with a pair of lift arms that are rotatably raised and lowered about a pivot, a rotary joint that communicates with a hydraulic drive source is built into the pivot of the lift arm, and that communicates with the rotary joint to raise and lower a bucket. A cargo handling device for an industrial vehicle, characterized in that the hydraulic drive system controlling the lift arm is installed in the main body of the lift arm. (2) The device according to claim 1, wherein the hydraulic drive system installed in the lift arm is a dump cylinder that shares a pivot with the lift arm.
