The DN28 Steel Single Hydraulic Acrow Prop Jack is a hydraulic support component designed for use in fully mechanized coal mining faces and light-duty roof caving systems. It operates under a working pressure of 31 MPa and delivers a maximum working resistance of 200 kN, with a minimum height of 2100 mm and a maximum height of 2800 mm. The cylinder diameter is 90 mm, and the base area measures 120 mm by 120 mm. The unit weighs 74 kg and is built for dynamic load balancing and lateral thrust in confined underground environments.
The jack is constructed from high-strength carbon steel with surface treatments to resist abrasion and corrosion in high-moisture mining conditions. It requires MT76-compliant emulsion fluid for operation, which must be filtered and replaced regularly to prevent seal degradation and internal friction damage. This model is one variant in a series that includes pushing jacks, equilibrium jacks, and anti-skid units, each engineered for specific roof support functions in coal mining frames. The design follows standard Chinese mining equipment specifications without certified international compliance claims.
These jacks are primarily purchased by coal mining operators in Asia and Eastern Europe for use in longwall and mechanized mining setups. Buyers typically order in batches of 50 to 200 units depending on face length and support density. Packaging is in steel crating with rust inhibitors, and delivery is FOB Qingdao or Tianjin. Lead time is confirmed upon order. No certifications are listed; buyers must request test reports for material composition and pressure endurance before shipment.

Sourcing DN28 Steel Single Hydraulic Acrow Prop Jack from China Coal Industry And Mining Group - China Import Guide
Before ordering, verify the jack’s material composition and pressure test records. Request a copy of the hydraulic test report showing performance at 1.5x the rated pressure of 31 MPa. Confirm the cylinder bore and piston rod finish with surface roughness measurements, as poor machining leads to premature seal wear. Do not rely on supplier claims without documented evidence.
Confirm the Incoterms and lead time with the supplier. Delivery is typically FOB Qingdao or Tianjin, with lead times of 30 to 45 days after deposit. Packaging is in steel crates with desiccants; request photos of packed units. Payment terms are usually 30% advance, 70% against bill of lading. Ensure the contract specifies inspection rights before shipment.
Perform a visual and dimensional inspection upon arrival. Check for dents, weld cracks, and alignment of the base plate. Measure the stroke length with a tape to confirm it matches the 700 mm specification. Test the hydraulic function with clean MT76 fluid under controlled pressure. Retain samples of fluid and seals for lab analysis if performance issues arise. Retain all documentation for traceability.
