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. Products are stated to have IATF16949 and Coal Mine Safety Mark certifications, with additional ISO45001:2018, ISO14001, and CE-related capability reported.

After-Sales capabilityThe company states that it provides technical training and after-sales service, and lists equipment installation, training, repair, maintenance, and debugging among its overseas service offerings.

Specific customer names, project references, order histories, or verifiable case studies are not provided.

Product Q&A

Q:What is the brand name of your products?

Generally, we use our own brand 'WTJX', OEM is also available as required.

Q:What causes hydraulic cylinder internal leakage?

There are 3 main reasons causing internal leakage : Overload, polishing is not well controlled, bad seal kits. As is known to all, vehicles in China are often overload,our products all designed to bear the overload power. We have numerical control machine to assure the polish processing. And we use the imported seals to meet customers' demands.

Q:Does your piston rod get ruptured easily?

Hard chrome plating quenched and tempered 45# steel for piston rod to assure sufficient hardness and toughness.

Q:What about the quality feedback of your products?

Guarantee the quality from the raw material. We have cold drawing production line and nickel-chrome electroplating production line, so we can produce cold-drawing pipe and hard-chrome pipe used for hydraulic cylinder!

Q:How is about working life of powered roof support hydraulic cylinders?

European standard EN1804-2 requires that the functional reliability of props and supporting jacks including their extensions should not be damaged after 21,000 loading cycles. Chinese national standard GB 25974.2-2010 Hydraulic supports for coal mines Part 2: Technical conditions for props and jacks 4.5.8 Durability, columns (including extensions) and supporting jacks should not fail after 21,000 loading cycles. Jacks should not fail after 10,000 loading cycles. The working life of our props and
