HYDRAULIC CYLINDER FOR VIBRATORY ROLLER
VR hydraulic cylinder is a kind of high pressure and heavy duty cylinder. They are utilized in different hydraulic vibratory roller. which is ideal for non- cohesive soils, gravel, macadam, sand gravel HYDRAULIC SYSTEM combination and different concretes. it’s indispensable compaction tools for highway mine street ,dams, airports, harbors, sector ground and building bottom.
1. High intensity…Fatigue design adaptive cylinder designed as per loading frequency evaluation are applied, and piston rod selection, digesting technology, welding technology are inspected through ultrasonic fault detection. Since it is designed for high pressure operation, it is featured in high strength and high reliability.
2. Sealing system…seal bands of NOK from Japan and Parker from United states that may sure highly safety 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 could be changed; the cylinder inner areas manufactured according to appropriate intensity and sizes have superb 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 features…valves with slower stroke, counting stability end emergency close can be installed easily according to requirements. The concealed types can absorb the effect of buffer device at the end of stroke.
Vibratory roller hydraulic cylinder we produces is a piston design cylinder, it can be matched for the latest models of of vibratory roller. They period used for changing path. We can style and make different specifications steering cylinder in accordance to customers’ requirements
