Therefore welcomed by users, has been great development. Bridge crane is mainly composed of the mechanical parts, metal structure and electrical three parts. The mechanical part is lifting, running, amplitude and rotating mechanism, metal structure is composed of lifting body, is the main installation of various institutions and support them all the weight of the part. Electric is a lifting movement of energy, the agencies are separately driven. Constitute the main bridge crane metal structure part is the bridge, it is in the workshop crane beam transverse frame on both sides of the track, and along the track before and after operation. According to the requirements of the bidding documents of an enterprise and the design specification of crane GB/T3811-2008, performance evaluations of 50/10t×25.5m double beam bridge crane were calculated, and draw the three-dimensional structure and two-dimensional structure diagram. At the beginning of this article, the main structure of 50/10t×25.5m double beam bridge crane were calculated. Select the carts wheels, trolley wheels, trolley tracks and other major components cranes.The structure of the bridge was designed to achieve the requirement of economical efficiency, and also intensity and stiffness was checked to make sure its safety. The double beam bridge structure includes the Crane Girder and the end carriage. This kind of structure has better stiffness and manufacturability. Considering the disposal of crane and different parts, the authors calculated through multiple data to select the optimal results. Finally, the goal of better crane performance and rationality and compactedness of all parts of crane was achieved. At last, most of the parts of the design characteristics of the selected are universal, standardized, serialized, the main technical parameters are in accordance with ISO standard, implement the state and all the latest promulgated crane industry standards. In one words, the safety and reliability of this Crane can be confirmed. key words：Bridge crane,The bridge structure，Metal structure，Three-dimensional model，The 2D engineering drawings III
