In order to accomplish this job, there is mechanism in the hoist crane which makes the goods move along the space in three directions. The bridge type hoist crane carries the goods to move in the rectangular plane depending upon the combination of the hoist crane movement mechanism and the car movement. The hoist crane plays an important role in the modern age. It is possible to realize the mechanization of main technical process and assistance work with the help of the hoist crane. The hoist crane can improve the production efficiency greatly in the assembly line and production workshop. This paper mainly completes the design of main-body structure and checking up calculation of the bridge-type hoist crane. Box-girder bridge type is adopted which is made up of two main beams and end girders. The main beams have walking platform on outside plates and welded with end girders to form rigid structure. For transportation convenience, joints are adopted in the middle of the end girders, and connected together with junction panels, angle-steels and bolts, which brings about transportation convenience and easy fixing. The car rails are fixuped on up-plates of the main beams which are welded in the middle of the up-plates. The hoist crane bridge types and the structural cross sections are chosen correct to ensure their intensity, the rigidity and the stability in the use process. Meanwhile, the structure manufacture technology capability, materials saving, fixing and convenience of maintenance and so on are paid attention to.
