◆ Unique metal support ring welded structure allowing good cylinder stability and high cylinder expanding resistance；
◆ The cylinder barrel surface is subjected to plating，corrosion prevention and resistant to abrasion，Prolonging the service life；
◆ The special high strength seamless steel tube with thin wall design enhances the deflectivity resistance of the hydraulic cylinder.
◆The unique sealing design avoids the leakage which may occur in the harsh environment；the combination of one Y-shaped high pressure polyurethane seal ring and one O-ring in the cylinder barrel ensure the excellent sealing property in both high and low pressure conditions to meet the requirement of harsh environment；
◆The unique extended guide sleeve enables the lifting more stable；
◆The interior closing ring enhances the safety；
Multi-stage hydraulic cylinders are suitable for tippers with the compartment length within 4800-9600mm，carring capacity with in 42t-100t.
