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 suitable for non- cohesive soils, gravel, macadam, sand gravel mixture and various concretes. it’s indispensable compaction equipment for highway mine street ,dams, airports, harbors, industry ground and building foundation.
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. As it is definitely designed for ruthless operation, it is showcased in high intensity and high reliability.
2. Sealing system…seal rings of NOK from Japan and Parker from United states that may sure highly security when work in aerial place. They are put on prevent grit and dirt, reduce oil leakage.
3. Cylinder body…the thickness of cylinder body and flange could be changed; the cylinder inner surfaces manufactured as per appropriate intensity and dimensions have excellent roughness and rigidity end better wearing capacity after roll finishing. They have 100% nondestructive test.
4. Piston rod…high frequency quenching followed by hard chrome plating to boost rust proofing and wear and scar resisting performance.
5. Safety/buffer functions…valves with slow stroke, counting balance end emergency close can be installed easily according to requirements. The concealed ones can absorb the impact of buffer device by the end of stroke.
Vibratory roller hydraulic cylinder we produces is a piston design cylinder, it could be matched for different HYDRAULICS DRIVE models of vibratory roller. They era used for changing path. We can design and make different specs steering cylinder according to customers’ requirements
