Undertook some National high-tech projects, such as DCY900 Girder carrier research project, one of China’s National projects called 863 projects, and successfully made it in 2004. Besides, undertook DPG500 Rail Layer Research project issued by the national Railway Department and successfully made it in 2006, as well as Df900 bridge fabrication machine and DLT900 type-mounted gantry crane.
Developed by Dafang people, DCY series self-propelled hydraulic transporter is a high-tech product integrating Mechanical, Electronic and Hydraulic, and our company holds independent intellectual property right on this, besides, DCY series transporter as well as double-tube safety valve which is used in the transporter have gained National patents, the patent NO. is ZL 01 2 40166.8 and ZL 03254678.5 relatively. The equipment uses the technology of hydraulic driving, hydraulic suspension, independent steering, platform hydraulic leveling and CAN-BUS micro-electronic control, etc. With 8 years’ constant research & development, the equipment has come to the 6th generation which is more reliable than the previous ones, no matter on design philosophy, manufacture & assembly arts, test and experiment, and the performance & reliability has reached international level. DCY series transporter is used for the displacement of steel blocks in shipyards, in steel plants as well as for the displacement of pre-fabrication bridge girders in highway & railway express construction.
