Dual acting single piston rod cylinder excavator hydraulic cylinder with High intensity

This series cylinder  is suitable for noncohesive soils,gravel,macadam,sand gravel mixture and various concretes.It\'s indispensable compaction equipment for highway mine road,dams,airports,habors,industry ground and building base. 

Features

1.High intensity...Fatigue design,adaptive cylinder designed as per loading frenquency analysis are applied,and piston rod selection,processing technology,weiding technology are inspected through ultrasonic fault detection.As it is designed for high pressure operation, it is featured in high intensity and high reliability.

2.Sealing systems...seal rings of NOK from Japan and Parker from USA that have good lifetime.They are applied to prevent grit and dust,reduce oil leakage.

3.Cylinder body...the thickness of cylinder body and flange can be changed, the cylinder inner surfaces manufactured as per appropriate intensity ang diamensins have excellent roughness and rigidty and better wearing capacity after roll finishing.They have 100%nondestructive test.

4.Piston rod...high frenquency quenching followed by hard chrome plating to improve rust proofing and wear and scar resisting performance.

5.Safety/buffer functions...valves with slow stroke,counting balance and emergency close can be installed easily according to requirements.The concealed ones can absorb the impact of buffer device at the end of stroke.
