Supplier typeThe supplier is identified as a construction-machinery manufacturer/supplier offering truck cranes, excavators, wheel loaders, road rollers, bulldozers, concrete pumps, crawlers, and cranes. It reports annual truck-crane production of 5,000 pieces and exports primarily to Europe, with 90% of total sales from exports.

CertificationsThe company states that it has passed ISO9000, CE, SGS, and other product certifications. A BV-conducted supplier audit is also documented with an SGS report period from February 12, 2025 to February 11, 2026; however, the audit evaluation result is recorded as 0 without further interpretation.

After-Sales capabilityThe supplier describes a one-year warranty, spare-parts supply, installation, maintenance, training, and technical advice. However, its service-capability assessment, corrective-action, and complaint-handling procedures have no written records, and it reports no overseas warehouse, showroom, agent, or branch, limiting evidence of locally deployed overseas support.

R&D capabilityThe supplier offers ODM services and OEM services for popular brands, indicating product-development and manufacturing support capability. It launched no new products in the previous year and has no available SDK, so evidence of recent product innovation is limited.

Production capacityThe supplier reports 5,000 truck cranes in annual output, 50 quality-control staff, 15 years of staff experience, and one-month off-season lead time. Peak-season lead-time data is inconsistent across the records, ranging from two to six months in one entry and two to three months in another, but the stated production volume provides explicit evidence of manufacturing capacity.

Customization capabilityThe supplier explicitly provides customization from customer designs and samples, as well as ODM services. These records directly support both design-based customization and original-design manufacturing capability.
