3 stages multi-section telescopic sleeve cylinders

Multi-stage hydraulic cylinder features: The working stroke can be very long and can be shortened when not in operation. Suitable for long travel distances where space is limited, e.g. telescopic boom for dump trucks and cranes. When the telescopic hydraulic cylinder is extended step by step, the effective working area decreases gradually. When the input flow rate is unchanged, the outreach speed increases gradually; when the external load is unchanged, the working pressure of the cylinder will increase gradually. When the external load remains constant, the working pressure of the cylinder will increase gradually. Therefore, multi stage hydraulic cylinder is used where the cylinder needs to be tilted or rotated vertically.
