Since the project started on October 18 , 2011 , it has experienced many difficulties. It faces many unfavorable factors such as short construction period, first construction, late planning, and insufficient staff in the Spring Festival. However, Changxing Section Manufacturing Department is united in the company . Inspired by the entrepreneurial spirit of “ being striving for first-class †, all departments have clearly defined the division of labor, and do a good job in the distribution of production tasks, technical disclosure, labor competition and logistics support. It is hard to complete the production tasks on time and in quality before the Spring Festival. Because it is the first time to build a 800- ton gantry crane, Changxing Section Manufacturing Department has set up a working group led by the Deputy Minister. The workshop departments work together to seize the production preparation and technical process, organize relevant personnel training and evidence collection, and timely solve the problem. Various problems, actively optimize the construction plan, and put every program to the door. During the construction, because the reinforcement method according to the original drawings will cause deformation in the process of segment turning, the manufacturing department will report to the Comprehensive Technology Department in time and communicate after many times, and the method of adding additional pipes is confirmed to ensure the segmentation. " Flatness " , the accuracy is effectively controlled. In particular, in the segment construction, the deformation of the welding process is caused by thin plates. The manufacturing department has adopted methods such as controlling the welding current and voltage, improving the welding sequence, and fixing the steel in some easily deformable places. Controlled the deformation state; secondly, the manufacturing department successively adopted the " reverse creation " and " side creation " methods for comparison, and finally selected a more suitable " reverse creation " method, which not only saved the tire frame tooling material but also positioned construction. Provided convenience, and accumulated experience for the construction of 1,800 tons of gantry cranes in the second phase of the next phase, laying a solid foundation.
