Our design team have long been engaged in the R&D and field application of TBM drive system (bearings, seals, gear & shafts). Combining market-leading gear and bearing simulation software and finite element analysis software, we conduct full checking and risk assessment of all product designs.

The Changsha-Zhuzhou-Xiangtan region has a mature TBM equipment industry chain. Our Xiangtan base fully utilizes this advantage to provide most cost-effective TBM products. At the same time, We also undertake TBM repair and transformation business.

According to customer needs, we offer two major categories of products:

High-power high-speed tunneling:
Adopting the traditional slewing bearing layout, high-power water-cooled planetary reducer and motor. At the same time, strengthen the shield body and cutter head to adapt to large torque.
Advantages: High tunneling speed.
Disadvantages: High cost; Slightly higher system complexity.

Cost-effective medium-speed tunneling:
If customers have no rigid requirements for tunneling speed, the product can appropriately reduce power and adopt the traditional rolling bearing layout (retaining the cutter head tool change channel) and correction system more commonly used in the pipe jacking machine.
Advantages: Low cost, simple system, and higher reliability.
Disadvantages: Slightly longer machine head length and low tunneling speed.

In addition, we are also responsible for the design of auxiliary systems such as ventilation and slag transportation (belt, mine car and other methods are available for selection), and coordinate first-class suppliers for production.
