The Crane and conveying machinery department is mainly engaged in the research and development, design, manufacturing, and general contracting of crane and conveying machinery in the fields of water conservancy, electricity, ports, shipbuilding, construction, and transportation. With nearly 70 years of research and development experience, we have undertaken dozens of national scientific research and export aid tasks. In recent years, our department has integrated advanced technology with new design concepts to optimize product structure, distribute stress more reasonably, run more smoothly, and operate more flexibly. We have also adopted advanced technologies such as PLC control, variable frequency speed regulation, DC speed regulation, human-machine interface, and wireless remote network control to make the electronic control system more user-friendly and intelligent. Especially in the design and manufacturing of cable cranes, portal cranes, overhead cranes in power plant buildings, dam crest/tail water gantry cranes, and fixed hoists for hydro-power station construction, it is in a leading position of the industry in China.
