Double Acting Hydraulic Cylinders for 5-30 Ton Dump Trucks

Premium Quality Hydraulic Cylinders - Quality Assured

1. Internals:Cylinder barrel adopts GUOYUE EU/US metallurgical standard CD250 structure. Barrel material: 45#, 42CrMo, or 27SiMn. Bore honed to H8 precision with surface roughness Ra<0.4μm. Heads, base, trunnions, and pistons are exclusively made of 45# steel; no cast iron or cast steel components are used.
2. Buffering:Multiple buffering options including fixed and floating buffer structures to ensure effective deceleration across various pressures and speed ranges.
3. Welding:100% ultrasonic impact treatment applied to all pressure-bearing and load-critical welds. This eliminates weld stress (removal rate ≥90%) and significantly enhances weld fatigue strength.
4. Sealing:All cylinders exclusively use premium imported seals from Japan NOK, Sweden Trelleborg, Germany Merkel, and GP. No domestic seals are utilized.
5. Testing &Certification:Factory testing strictly complies with GB/T15622-2005 "Hydraulic Fluid Power - Test Methods for Cylinders" and internal premium standard Q/GAKY014-2023. Includes provision of factory test reports and product qualification certificates.
6. Warranty: One-year warranty from shipment date. Free repair or replacement provided for defects arising from design or manufacturing within the warranty period.

Key Advantages:
Bidirectional Power Extends/retracts under hydraulic pressure, enabling faster and more controlled dumping cycles. High Load Capacity Reinforced rods (60-90mm) and heavy-duty seals handle 200-350 bar pressure for 5-30 ton loads.
Durability Hard-chromed piston rods + wear-resistant coatings prevent corrosion in harsh environments.
Precision Control Adjustable cushioning reduces impact at stroke ends, extending lifespan.
Low Maintenance Self-lubricating bearings and replaceable seal kits minimize downtime.

Core Applications :
Dump Truck Beds Smooth lifting/lowering of heavy loads (soil, gravel, debris).
Construction Sites Reliable operation in mining, roadwork, and demolition.
Waste Management Durable performance in garbage/recycling trucks.
Agricultural Use Hauling crops, feed, or manure with consistent power.
Heavy Equipment Compatible with trailers, tippers, and off-road haulers.
