AI-Powered supplier vetting

SummaryThe supplier designs and manufactures trenchless engineering equipment, including multiple pipe jacking machine types, and also provides construction participation, technical training, and demonstration services. It reports one assembly line, stated annual productivity of 100 sets for each listed machine category, in-stock capability, and valid manufacturing contracts with associated subcontractors. The supplier offers 3D software design and broad customization services, but reports no new products in the past year. Quality, complaint handling, corrective-action, and after-sales procedures are documented, while supplier approval records lack signatures or dates. It has no overseas warehouse or showroom, and continuous production-volume reconciliation is not performed. Evidence is insufficient to confirm certifications, financial credibility, or customer cases.

Supplier typeThe supplier is an engineering-equipment manufacturer and service provider focused on trenchless construction. Its stated activities include designing and manufacturing equipment, product development, marketing, after-sales service, equipment rental and sales, pipe jacking construction, technical training, and construction demonstrations.

After-Sales capabilityThe supplier explicitly states that it provides pre-sale, sales, and after-sales service, including product consultation and usage guidance. It also reports in-stock capability, written service-capability assessment procedures with records, and documented complaint-handling and corrective/preventive-action procedures; however, it lacks an overseas warehouse and showroom.

Production capacityThe supplier reports one assembly line and annual productivity of 100 sets for each of five listed pipe-jacking machine categories. It has valid manufacturing contracts with associated subcontractors and in-stock capability, but does not conduct continuous quantity reconciliation for each batch or production lot.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, supported by 3D software design services. This directly demonstrates broad customization capability.

Product Q&A

Q:What parameters are required to get a price and technical solution?

Please provide: 1. Project total length and section details; 2. Pipe type and dimensions (CRP/RCC/steel, length, diameters); 3. Project info (water supply/sewage); 4. Underground water level; 5. Soil investigation report; 6. Project drawings.

Q:What is the warranty period and coverage?

We provide a 12-month warranty. We cover spare parts and service fees for quality or assembly issues. Users are responsible for costs if troubles are caused by misuse or human factors.

Q:What is the delivery time for the machine?

The delivery detail is 60 days after receiving a 30% deposit. The average lead time is one month for both peak and off-season.

Q:Does the machine require surface excavation?

No. This is a trenchless (non-excavation) construction technology. The machine pushes pipes underground from a launch shaft to a receiving shaft, avoiding surface disruption.

Q:What is the maximum steering deviation angle?

The machine features high precision construction with a deviation adjustment angle of up to 5.5 degrees for up, down, left, and right corrections.
