It is used in the railway freight yard, the port and factory. The moving mechanism is one basic mechanism of the gantry crane. Design quality of moving mechanism has the direct influence to the performance of gantry crane. Therefore, design of moving mechanism have important significance to the crane design. The thesis has mainly completed following works: (1) The mechanism scheme design， (2) the mechanism and components of the design and calculation，(3) The mechanism part of main technology index check，(4) Operation mechanism design of general layout and component design. The thesis introduces the effect and classify of the crane at first, then it introduces the developing current of modern cranes. Through the introduction all of us can get some knowledge about crane more or less. The primary content of the thesis is designing the right moving framework to fit the work environment according to the known parameter. During the designing time, the most important thing is choosing the right project of the whole framework to drive the crane, choosing the driving project, the disposing project of the retarder and driv
