The product features of XUANXUAN

The main drive parts are selected

Dinamic / Brevini gearbox

Siemens / ABB / ELIN Motor

The main drive box

adopts polyurethane seals and high-temperature grease automatic lubrication system to solve the problems of water ingress, mud seepage and oil leakage, take into account the durability and service life of the seals, and ensure the effective lubrication and service performance of the main drive.

Structural design of the main drive shaft

A more scientific and reasonable structure is adopted to achieve the effect of enhancing the performance and dispersing the supporting load. This ensures that the power box is more stable and durable during dynamic loading.

PLC

We use Siemens SIMATIC PLC controllers, combined with actual construction experience, from a humanized point of view, to design a more intuitive monitoring/operation interface, more convenient and fast operation and control mode, and strengthen the practicality and durability that are more suitable for on-site construction use scenarios.

Shield & Cutterhead

1.The shield shell is made of high-quality steel to ensure the rigidity of the overall shell, and the outer protective layer of the cutterhead is made of SAAB HARDBOX wear-resistant steel plate.
  2.Tailor-made shell according to the actual pipe diameter of the project, cut according to high standards with high-precision numerical control, reduce the construction settlement, and meet the higher requirements of the project.

Slurry system

The slurry feeding/sludge discharge system can realize internal and external circulation, bypass, external water supply, and a variety of slurry circulation modes, effectively solving the problems of slag deposition and large friction resistance of pipelines. The cone crusher chamber is equipped with a carbide nozzle for high-pressure water injection to prevent mud cake formation in the cutterhead

Xuanxuan's manufacturing philosophy

With 34 years of manufacturing, R&D and production, we have accumulated rich experience to achieve a high degree of self-development and self-production, keep up with the market needs, customize the design and production of tunnel construction equipment, and create customized high-quality products that meet the needs of trenchless construction 100% of the use needs.
Pay attention to customer feedback is highly in line with the actual use of the product, is our most basic and primary requirement for the production of underground construction equipment, since the establishment of the enterprise, we have invested a lot of money to build their own construction technology team, only to achieve our own requirements and the solemn commitment to customers, keep promises, quality and quantity with customers to complete the construction project. A sustainable development enterprise must be able to achieve a win-win situation with its own customers, which is also the core development strategy of our company.
