Can you help with installation or cylinder selection?

Yes, we have 25 experienced engineers ready to help. Contact us with your machine details, and our engineers will design the exact products to match your needs.

What causes internal leakage and how do you prevent it?

Internal leakage is often caused by overload, poor polishing, or cheap seals. Our products are designed to bear overload, use advanced polishing equipment, and import top-brand seals.

How can I get a quote or buy a cylinder?

Please provide the drawing with technical requirements, model number, tipping capacity, number of stages, closed length, mounting type, size, and quantity.

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. Service management has written procedures, records, approved-supplier information, and corrective/preventive-action procedures, but no overseas warehouse, showroom, agent, branch, or offline trade-show participation is reported.

R&D capabilityThe supplier reports new products within the past year, ODM capability, broad R&D customization services, and 50 years of combined R&D-engineer experience. However, no SDK is available; this limits evidence for software or platform integration capability but does not negate the demonstrated product-development capability.

Production capacityProduction evidence includes numerical-control machine tools, a Longmen machining center, five production lines, 11–20 quality-control staff, and stated hydraulic-cylinder output of 300,000 sets. The supplier also reports finished-product inspection instructions that are uniformly followed and an off-season average lead time within 15 workdays.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization. Its company description also covers customized preliminary design, development, product selection, and design-scheme finalization, indicating broad engineering customization support.

Client casesThe product portfolio is identified for dump trucks, mechanical equipment, engineering machinery, and hydraulic systems, and the supplier states that it provides OEM services for well-known brands. Specific customer names, project references, order histories, or verifiable case studies are not provided.
