Combining the advantages of booming and transporting together, it has the features of compact structure and easy operation，not only saves the labor force, but also decreases the labor intensity and increases the efficiency of working. It is widely used in traffic transportation, docks and warehouses. In this paper, based on the investigation and feasibility analysis of TMC, the winch mechanism, the arm-changing mechanism and the swing mechanism of the TMC 6.3T were designed from the mechanics angle. The winch mechanism consists of hydraulic motor, decelerating machine, ratchet wheel stopping machine and reel. Decelerating machine lowers the speed of the hydraulic motor for driving, and its size was defined according to the ratio of the speed variety. The reel is to wind or unwind the load hoisting wire rope. The sizes of the reel and the wire rope were designed according to the work condition and the rise weight. Ratchet wheel stop is used to stop the converse motion, and it was decided by the pressure the gear bears. The arm-changing mechanism is the system that changes the arm range of the boom-crane. It includes the arm system and the arm-changing moving system. In this paper, flexible arm type and box form structure were used. Cylinder bodies are fitted on the boom. The working range of TMC can be realized by the extension or retraction of the cylinder body. The swing mechanism contains swing bearing and swing driver. Bearings, worm-and-wheel steering gear and hydraulic motor were adopted. This structure has the advantages of light weight, reliable force and smooth action.
