Construction Features
Internals: Cylinder barrel meets GUOYUE EU/US metallurgical standard CD250 structure with materials including 45#, 42CrMo, or 27SiMn. Bore honed to H8 precision with surface roughness Ra<0.4μm.
Components: Heads, base, trunnions, and pistons exclusively made of 45# steel with no cast iron or cast steel components.
Buffering: Multiple buffering options including fixed and floating buffer structures for effective deceleration across various pressures and speed ranges.
Welding: 100% ultrasonic impact treatment on all pressure-bearing and load-critical welds, eliminating weld stress (removal rate ≥90%) and enhancing fatigue strength.
Sealing: Premium imported seals from Sweden Trelleborg, Germany Merkel, and GP.
Testing: Complies with GB/T15622-2005 standards and internal premium standard Q/GAKY014-2023, including factory test reports and product qualification certificates.
Performance Advantages
High Load Capacity: Engineered for 5,000-25,000 kN thrust forces in hard rock conditions
Precision Alignment: Ensures ±1mm boring accuracy for tunnel integrity
Abrasion Resistance: Hard-chromed rods with ceramic coatings withstand quartz-rich geology
Minimal Maintenance: Reinforced seals endure 10,000+ hours in gritty environments
Custom Integration: Tailored stroke/mounts fit specific TBM designs
Rapid Response: Direct OEM supply reduces downtime
Application Scenarios
Hard Rock Tunneling: Gripper thrust systems in granite/basalt formations (e.g., mountain rail/road tunnels)
Hydroelectric Projects: Main drive cylinders for headrace/tailrace tunnels under 200 MPa rock pressure
Mining Shafts: Shaft-boring machines in deep ore mines with high geostress
Dry Geology: Stable sedimentary rock tunnels without pressurized groundwater ingress
Quality Assurance
Pre-production samples provided before mass production
Final inspection conducted before shipment
1-year warranty from shipment date
Free repair or replacement for defects arising from design or manufacturing within warranty period
