Abstract Bridge crane compared to other forms of crane, has the advantages of high work efficiency and high stability. Through searching a large number of crane data,aware of the overhead traveling crane design, working principle and the structural composition. Also understand that the bridge crane on the development trend of CNC, precision and large scale. Through research and development of a bridge crane, of bridge crane running mechanism, lifting mechanism and design calculation of the focus of the paper. The pulley, wire rope and drum design is constituted the play of lift mechanism design; design of master-slave wheel, orbit design and Scheme design of large car run institutions constitute the mechanism design. At present, the development of bridge crane is relatively simple, after should move towards more persified direction development, in the hope that we in overhead traveling crane development into more profound research, put forward more more novel concept.
Key words: bridge crane; development trend; hoisting mechanism; big trolley running mechanism
