AI-Powered supplier vetting

SummaryThe supplier manufactures hydraulic cylinders and hydraulic lifting systems for dump trucks, engineering machinery, and other mechanical equipment. It provides customized design, development, selection, technical training, and after-sales support, with stated ODM and OEM capabilities. Evidence indicates structured quality, supplier-service, inspection, and corrective-action procedures, alongside multiple management and product certifications. Production resources include five production lines, 50 years of combined R&D engineer experience, 11–20 quality-control staff, and stated hydraulic-cylinder output of 300,000 sets. Overseas support is limited: no overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported, although installation, training, repair, maintenance, and debugging services are listed. Financial information is represented only by year labels, so credibility cannot be assessed from the provided data.

Supplier typeThe supplier is a manufacturer of telescopic, engineering-equipment, mechanical-equipment, and hydro-pneumatic suspension cylinders, hydraulic lifting systems, and hydraulic components. Its five production lines and stated hydraulic-cylinder output support classification as a specialized hydraulic equipment manufacturer.

CertificationsThe supplier reports QHSE, OHSAS/OHSMS 18001, TS 16949, and ISO 9001 supplier-management certifications, plus China safety and environmental, occupational health and safety, integrated management, and DCMM Level 2 certifications.
