HYDRAULIC CYLINDER FOR VIBRATORY ROLLER
VR hydraulic cylinder is a type of high pressure and durable cylinder. They are used in different hydraulic vibratory roller. which is ideal for non- cohesive soils, gravel, macadam, sand gravel combination and various concretes. it’s indispensable compaction apparatus for highway mine street ,dams, airports, harbors, sector ground and building bottom.
1. High intensity…Fatigue style adaptive cylinder designed according to loading frequency evaluation are applied, and piston rod selection, processing technology, welding technology are inspected through ultrasonic fault detection. Since it is definitely designed for ruthless operation, it is showcased in high strength and high reliability.
2. Sealing system…seal bands of NOK from Japan and Parker from USA that may sure highly security when work in aerial place. They are applied to prevent grit and dirt, reduce oil leakage.
3. Cylinder body…the thickness of cylinder body and flange can be changed; the cylinder inner surfaces manufactured according to appropriate intensity and dimensions have excellent roughness and rigidity end better putting on capacity after roll completing. They have 100% non-destructive test.
4. Piston rod…high frequency quenching followed by hard chrome plating to improve rust proofing and wear and scar resisting performance.
5. Safety/buffer functions…valves with slower stroke, counting stability end emergency close could be installed easily according to requirements. The concealed types can absorb the effect of buffer device by the end of stroke.
Vibratory roller hydraulic cylinder we produces is a piston style cylinder, it could be matched for the latest models of of vibratory roller. They era used for changing direction. We can style and make different specifications steering cylinder according to customers’ requirements
