Product Details
Function
The core hydraulic actuator that supports the telescopic movement of the boom
Cylinder diameter
80-200 mm
Working pressure
25-35 MPa
Features
Extreme pressure bearing capacity
The working pressure is 25-35 MPa, with a peak pressure exceeding 40 MPa, supporting a thrust of 20-300 tons, and stabilizing the impact load of concrete pumping.
Impact resistance and stability
Reinforced cylinder/piston rod material (such as 27SiMn alloy steel), multi-layer sealing system, absorbing arm vibration and instantaneous impact.
Millimeter level synchronous accuracy
Combined with proportional valve closed-loop control, the synchronization error of multiple cylinders is ≤ 2mm, ensuring flexible extension and precise positioning of the boom.
Long service life
Surface treatment (hard chrome plating 20-30 μ m+phosphating), corrosion-resistant and wear-resistant, with a service life of ≥ 100000 cycles.
Security redundancy design
Built in buffer device+emergency hydraulic lock, the boom slowly retracts in case of sudden pressure relief to prevent falling.
