Backhoe Type Integral Hydraulic Breaker
HOPE Backhoe Type Integral Hydraulic Breakers feature a fully welded, high-rigidity monoblock design engineered for backhoe loaders and excavators ranging from 0.5 to 100 tons. By combining precision-tuned hydraulic flow dynamics with forged alloy steel components, these breakers deliver high impact energy, minimal housing deflection, and low vibration transfer to the primary carrier.
Features
Solid integrated alloy steel frame
Key components are made with high-strength alloy steel to improve wear resistance and extend service life. The fully welded one-piece design adds rigidity under heavy continuous use, lowering the chance of cracks or internal damage on busy job sites.
Stable hydraulic performance
The hydraulic system is tuned to maintain consistent oil flow and reliable impact frequency. This setup reduces vibration passed to the host machine, helping protect your equipment and keeping operators more comfortable during long shifts.
Simple mounting and good adaptability
This integral hydraulic breaker series fits most standard backhoe loaders and mid-sized excavators with straightforward installation. It works well in tight urban spaces, rural job sites, and small-scale breaking tasks.
Low maintenance for daily use
The simplified internal layout and heavy-duty sealing parts mean less frequent upkeep. Less downtime helps lower total operating costs for regular construction projects.
COMPONENT MATERIAL SPECIFICATIONS
To ensure maximum tensile strength, fatigue resistance, and operational lifespan under continuous cyclic loading, critical components are precision-machined from forged alloy steels:
- Upper & Lower Head (Front & Back Head): 20CrMo Forged Steel
- Cylinder Body (Middle Cylinder): 20CrMo Forged Steel
- Control Valve: 20CrMnTi Forged Steel
- Piston: 40CrNiMo High-Strength Forged Alloy Steel
- Inner & Outer Bushings: 20CrMo Forged Steel
- Chisel (Tool Bit): 42CrMo Heat-Treated Forged Alloy Steel
- Side Plates / Bracket: Q335Mn High-Tensile Structural Steel
