More than 100 robotic employees are on the job for single girder overhead crane

On the basis of the original intelligent assembly line, DJCRANES has been equipped with more than 100 sets of internal seam welding intelligent robots, which will greatly improve the welding quality and work efficiency of the single girder overhead cranes. The welding robots have been put into use one after another.


Intelligent Robots

We plan to carry out 16 robotic welding lines to fully cover the internal seams of each team in the single beam workshop, in order to achieve the ultimate quality of the single girder overhead crane.

Intelligent Crane Welding Line Characteristics

Fully Automatic

This welding line combines a series of high-precision technology and many years of experience in the design and manufacture of cranes and automation. The automatic positioning of the products, the robot automatically finds the ribs, automatically identifies the starting position of the weld and passes the arc tracking technology during the welding process. Real-time correction. Automatically clear the gun, cut the wire, and spray the lubricating oil during the welding process to prevent the splash inside the protective nozzle from affecting the welding.

Fully Compatible

In the design stage, the workpiece welding rate was simulated and calculated in advance through 3D simulation technology. Single-beam products with a length of 10.5 m to 22.5 m can be welded regardless of size, and all sizes of equipment can be adapted in the length direction. Four robots automatically search for ribs and automatically distribute the workload according to the length of the workpiece.

Full Coverage

The single beam inner joint is welded once between the weld between the rib and the U-shaped groove or the weld between the slat and the U-shaped groove.

Zero Defects

Compared with manual work, the welds welded by the robot are excellent in shape, the weld width is uniform, the surface is flat, and the defect is basically zero.


Intelligent Robot

High Intensity

Due to the uniform width of the weld, the damage caused by the stress concentration on the weld is greatly reduced, and the average weld height is higher than that of the artificial weld, which greatly increases the strength of the product.

High Efficiency

Four robots work in tandem to automatically distribute the workload. Taking 5t-22.5m standard products as an example, the efficiency can be increased by 30% compared with manual welding.

High Precision

The running device is powered by a servo motor, equipped with a precision reducer and a high-precision rack and pinion to ensure running accuracy.
