Zeyu Equipment

Robotic Automatic Welding System
The company uses a robotic automatic welding system for the main chords of mast sections. This system offers stable performance, high working efficiency and a high degree of automation. The welding quality of main load-bearing structural components has reached the advanced level of international peers in the same industry.

Plasma Cutting Machine
Plasma cutting machines are used for blanking plate-type parts. They feature fast cutting speed, smooth cut surfaces, minimal thermal deformation, no oxide layer at the cut, and better weld strength.

Flame Cutting Machine
It has good rigidity. The crossbeam adopts a butt-welded square-tube structure. It features high precision, light deadweight and low inertia. All welded parts are subjected to vibratory stress relief treatment, effectively preventing structural deformation.

Zeyu Process

The company’s products make full use of group technology, modular design technology and finite element analysis (FEA) technology. Through years of experience, the company has acquired manufacturing processes for various models of the QTZ40, QTZ50, QTZ60, QTZ63, QTZ80, QTZ100 and QTZ125 series tower cranes, as well as the process for the SC200/200 construction hoist.
