What types of models are available?

Multiple models are available, ranging from DW06 to DW35, with varying max heights from 600mm to 3500mm and different load capacities.

How is the hydraulic prop operated?

It operates by injecting high-pressure fluid through a three-way valve to raise the cylinder, which then supports the roof beam until the valve is closed.

What is the working principle of this prop?

The prop uses emulsion fluid to force the live cylinder to rise; once it contacts the roof, the pressure chamber maintains constant pressure to support the load.

AI-Powered supplier vetting

SummaryThe supplier is a combined company with manufacturing, export, service, quality-control, R&D, and sustainable-development capabilities. It offers broad customization, reports new-product development in the past year, and provides ODM services. Manufacturing evidence includes multiple processing and finishing machines, inventory capability, valid contracts with associated subcontractors, and documented inspection and corrective-action procedures. Overseas service is available in Denmark, Colombia, India, and Georgia, covering installation, debugging, maintenance, repair, and training, but the supplier has no overseas warehouse, showroom, agent, or branch. CE and CCC product certifications are reported. Financial records are identified for 2021–2023, but their results are not provided. The supplier has OEM experience with well-known brands but no Fortune 500 collaboration reported.

Supplier typeThe supplier is identified as a combined company and reports manufacturing equipment, inventory capability, and valid contracts with each associated subcontractor. This supports a combined manufacturing and service-oriented supplier profile, although the exact ownership or operating structure is not further detailed.

CertificationsThe supplier reports CE and CCC product compliance certifications and an unspecified management-system certification described as “Others.” Product certification coverage is explicitly stated, but the specific management certification is not identified.

After-Sales capabilityThe supplier provides overseas debugging, maintenance, repair, training, and equipment installation in Denmark, Colombia, India, and Georgia. It has no overseas warehouse, showroom, agent, or branch, which limits local infrastructure but does not negate the stated service offering.

R&D capabilityThe supplier reports new products during the past year, provides ODM services, and has an available SDK. These statements directly support active R&D and product-development capability.

Production capacityProduction-related evidence includes cutting, painting, sawing, and shearing equipment; inventory capability; valid manufacturing contracts with associated subcontractors; and a one-month average lead time in both off-season and peak season. Documented finished-product inspection, supplier-service procedures, and corrective/preventive-action records further support operational control.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. The same broad service range is reported in both R&D and design-capability information, providing clear evidence of extensive customization coverage.

Client casesThe supplier reports OEM service for well-known brands and participation in the Changsha International Construction Machinery Exhibition. It reports no collaboration with Fortune 500 companies; therefore, some customer and market-exposure evidence exists, but detailed customer names, projects, or verified case outcomes are unavailable.
