AI-Powered supplier vetting

SummaryQingdao Tunnel Mine Equipment Technology Co., Ltd. is identified as both a trading company and manufacturer/factory in China, offering underground mining equipment and drivetrain products. The provided information indicates substantial operating capacity, including more than 10 production lines, 50 quality-control staff, and exports to multiple international regions. It holds ISO 9001 certification, and its after-sales offering includes operator, maintenance, and fault-diagnosis training, supported by spare-parts storage and an agent-based branch office. However, the available slices do not establish financial strength, current audit validity or outcome interpretation, R&D and customization capabilities, or specific customer cases. Overseas warehouse, showroom, agent, and trade-show status is also recorded as unknown.

Supplier typeThe supplier is classified as a trading company and manufacturer/factory, with a limited-company structure and a stated product portfolio covering underground loaders, mining trucks, utility vehicles, transmissions, torque converters, and axles. This supports a hybrid commercial and manufacturing role rather than a purely trading profile.

CertificationsThe supplier holds ISO 9001 certification. An SGS audit is recorded with a report period from July 20, 2024 to July 19, 2025, but the provided audit result value is not explained, and the stated validity period has passed relative to the current date.

After-Sales capabilityAfter-sales support explicitly includes operation, maintenance, and fault-diagnosis training. The supplier also describes spare-parts storage, on-site consignment storage, and a spare-parts branch office at an agent location, indicating structured support resources.

Production capacityThe supplier reports more than 10 production lines and 50 quality-control staff, while its product scope includes underground mining equipment and drivetrain systems. Factory locations are stated in Qingzhou and Xuzhou, supporting a demonstrated production setup, although actual output volume and capacity utilization are not independently clarified.

Product Q&A

Q:What is the model and type of the gearbox?

The model is TMG07543. It is a cycloidal layout, downshaft type transmission with four forward and three backward gears.

Q:What are the main technical parameters?

Rated input power is 75kW at 2400r/min. Working fluid is No.6 or No.8 hydraulic transmission oil. Main oil pressure is 1.6-1.9MPa.

Q:How does this gearbox solve overheating issues?

It uses a hydraulic torque converter with large circulation and large transmitted torque, which is not easy to heat up, solving the issue of overheating on long slopes.

Q:What are the benefits of the improved clutch structure?

The improved clutch structure reduces the burning of friction plates caused by inaccurate control of engagement time during the shifting process.

Q:What is the lead time for production?

The lead time is 3 months during peak season and within 15 workdays during the off-season.
