Main structure of this crane is designed with 4 girders and 6 rails. The features of this crane: integral processing technology and secondary assembly technology. For the first time assembly, the welding components sizes are fixed and processed by flat position welding to ensure high quality of welding seams; and the secondary assembly is for releasing welding stress before the integral processing of the bridge to ensure the stability and accuracy of product process precision. The two times assembly technologies are great help to ensure the precision of gauge, diagonal and span, as well as users' site installation.
