Our double cylinder hydraulic shears are built for extreme demolition environments. The main jaws are manufactured from NM500 wear-resistant steel, providing a Brinell hardness that resists abrasive concrete dust. The cutting blades are forged from 42CrMo alloy, capable of shearing through high-density rebar without deforming. Every pivot pin is induction-hardened to prevent ovaling under the 300 Bar driving pressure.
The “Double Cylinder” Engineering Advantage
Unlike single cylinder crushers, the Twin-Cylinder Configuration ensures balanced force distribution. The synchronized movement prevents the jaws from twisting when biting into offset reinforced concrete, protecting your excavator arm from lateral stress. The integrated Speed Valve regenerates hydraulic oil from the return circuit to the power side, increasing closing speed by 35% without consuming extra fuel.

Installation Compatibility (Golden Parameters)
Fitment Verification for 20T Class: To ensure a direct-fit installation on your Hitachi ZX200 or Doosan DH220, please verify the 80mm pin diameter and the 450mm-485mm pin center distance. We provide custom ear-width bushings to match your specific dipper arm.
Hydraulic reinforced concrete shear that can rotate 360 degrees. Excavator double-cylinder hydraulic shears are used for the demolition of scrap cars, scrap metal items, and concrete steel structures.
