three-unit telescopic hydraulic cylinder

High Reliability

Equipped with a mechanical sequence valve with a firing pin structure, it can realize the precise sequential telescoping of the three-stage hydraulic cylinder, greatly reducing potential faults such as movement jamming and misalignment, significantly prolonging the service life of the hydraulic cylinder and lowering equipment maintenance costs.

Excellent Low-Temperature Resistance

The high-quality combination of Q345E cold-drawn seamless steel pipe and low-temperature polyurethane seal endows the hydraulic cylinder with strong low-temperature adaptability. The hydraulic cylinder can work stably in an extreme severe cold environment of minus 40℃, breaking the limitation of low temperature on the operation of the hydraulic cylinder and expanding the applicable regional scope of the equipment.

Strong Adaptability

The precise parameter design can be adapted to the boom telescoping mechanism of straight-arm truck-mounted cranes of different specifications. It is easy to install and has good versatility, and can be adapted without a lot of modifications.

Smooth and Accurate Movement

The hydraulic transmission has a fast response. Cooperating with the coordinated control of the mechanical sequence valve, it ensures the smooth and impact-free telescoping movement of the three-stage hydraulic cylinder, and improves the operation accuracy and safety.
