The Drum Cutter install on the shield machine to become a construction master

But in fact, in addition to being installed on the excavator to perform independent work, the drum cutter can also be installed on the shield machine to become a part of the shield machine, so as to play its own role in precise construction. In May last year, the world's first super-large cross-section rectangular hard rock pipe jacking machine rolled off the assembly line in Xiamen, which attracted widespread attention in the industry. This equipment can realize the construction and application of rectangular pipe jacking in hard rock and composite strata, and solve the worldwide problem of hard rock treatment in blind areas of rectangular pipe jacking cutter head excavation.

Although the milling head here is similar in appearance to the axial drum cutter, it has actually undergone precise improvements. According to the actual needs, we have improved the shape of the traditional drum cutter, adopting the design of the overall linkage of the shell and the integrated drive, which makes the milling and excavation more efficient and more in line with the functions that it needs to show on the pipe jacking machine.

The key to officially solving this worldwide problem is the drum cutter. It is installed in the blind area of the pipe jacking machine to realize the milling and excavation in the blind area. In the whole equipment, it occupies a very small position and plays the smallest role of milling and digging. However, although the body is small, its function is large, and it is an indispensable part of the whole pipe jacking machine!
