Product Features — What Makes Our Crane Cylinders Different
Mobile cranes demand far more from hydraulic cylinders than ordinary equipment. It is not just about lifting and lowering. Our mobile crane hydraulic cylinders focus on high strength, impact resistance, and precise control.
Strong Pressure Bearing Capacity
The crane arm extends and retracts under heavy load, requiring continuous high pressure and instantaneous impact resistance. We use thickened cylinder barrels, high-strength alloy steel piston rods, and multi-pass welding structures for overall rigidity.
Stable Extension & Retraction
Shaking during lifting means unstable operation at best and danger at worst. We use buffer structure design and high-precision inner wall treatment to keep piston stroke smooth and free of jamming.
Tight Anti-Leakage Structure
Imported sealing components, double lip design, and dust rings reduce the risk of seal aging and extend the maintenance cycle.
Multi-section telescopic design: Our cylinders support multi-section telescopic configurations, compatible with multi-stage booms. Widely used in engineering cranes, off-road cranes, and truck cranes. Stability, safety, and long service life are the basic criteria for every Raydafon lifting cylinder.
