Its characteristic is: working stroke can be very long, when not working can shrink shorter. 

It is suitable for installation space is limited and the travel requirements are very long occasions, such as tipping bucket cars, cranes telescopic boom. When the telescopic hydraulic cylinder is extended step by step, the effective working area decreases step by step. 

When the input flow is constant, the overhang velocity increases gradually. When the external load is unchanged, the working pressure of the hydraulic cylinder gradually increases. The extension of the single acting telescopic hydraulic cylinder depends on the oil pressure, and the contraction depends on the weight or load. Therefore, for cylinder tilt or vertical rotation of the occasion
