Publish Time: 2025-04-23 Origin: Site
For contractors, miners, and demolition experts seeking long-lasting hydraulic breakers that thrive in harsh conditions, RAY Attachments delivers precision-engineered solutions. Our hydraulic hammers combine advanced metallurgy, rigorous quality control, and global support to outperform competitors. Below, we explore their technical excellence, diverse applications, and why they’re the ultimate choice for heavy-duty projects.
1. What is a Hydraulic Breaker? Key Applications & Industries
A hydraulic breaker (or rock breaker, concrete breaker) is a powerful attachment mounted on excavators, backhoes, or skid steers to break rocks, concrete, asphalt, and other rigid materials. RAY Attachments’ hydraulic hammers excel in:
Top 5 Application Scenarios
Mining & Quarrying
Primary and secondary rock breaking in open-pit mines.
Reducing oversize boulders for crusher feeding.
Why RAY?: 42CrNiMoA pistons withstand 500°C temperatures from prolonged friction.
Demolition & Construction
Demolishing reinforced concrete structures (bridges, buildings).
Trenching in rocky terrain for pipeline/utility installation.
Why RAY?: 20CrMo forged cylinders resist scoring during high-frequency impacts.
Roadwork & Tunneling
Breaking bedrock for highway foundations.
Tunnel profiling and overbreak removal.
Why RAY?: Precision-hardened bushings (58-62 HRC) minimize downtime in abrasive environments.
Port & Shipyard Operations
Breaking dock concrete or removing ship hull scale.
Why RAY?: Triple-layer corrosion protection (VCI bags + aluminum foil + epoxy coating) for marine environments.
Recycling & Scrap Processing
Fragmenting metal castings, slag, or automotive scrap.
Why RAY?: Shock-absorbing accumulators reduce vibration damage to host machines.
2. Hydraulic Breaker Components: Material Innovation for Extreme Conditions
Market vs. RAY Attachments: Critical Material Comparison
| Component | Market Common Materials | RAY Attachments’ Materials | Key Advantages |
|---|---|---|---|
| Cylinder Block (Front/Middle/Rear) | Front Cylinder: 20Crmo Forging, 40Cr, Cast Iron Parts Middle Cylinder: 20Crmo, 42Cr, Rear Cylinder: 20Crmo, 40Cr, cast iro | 20CrMo | Ensure the stability of the cylinder block, but also to achieve the same coefficient of thermal expansion of the cylinder block as a whole, reducing the risk of cylinder pulling due to high temperature |
| Piston | 40Cr、42Crmo、42Crnimo、GCr15 | 42CrNiMo | The 40CrnimoA material ensures the piston corrosion resistance and high temperature resistance, which can be applied to the harsh working environment. The coefficient of thermal expansion is close to that of the cylinder 20CrMO material. |
| Ring Bushes | 20CrMO、40Cr、42Cr、42Crmo | RHB45-RHB175: 20CrMo RHB175-RHB258: 42CrNiMo | Corrosion and high temperature resistance, and the consistency of the material of the piston, to ensure that the mechanical properties of the material is the same, to avoid the deformation caused by the difference of the material when working. |
Performance Breakdown
Cylinder Block (20CrMo Forging)
Hardness: 58-62 HRC vs. market’s 30-52 HRC.
Durability: 20CrMo’s toughness reduces micro-crack formation during high-frequency impacts (e.g., 1,200+ blows/minute).
Thermal Stability: Matched thermal expansion across front/middle/rear cylinders eliminates internal stress.
Piston (42CrNiMo)
Corrosion Resistance: Chromium-nickel-molybdenum alloy resists pitting in saline/acidic environments (e.g., coastal demolition, mining slurry).
High-Temperature Strength: Maintains structural integrity up to 550°C (critical for asphalt cutting or deep mining).
Ring Bushes
RHB45-RHB175 (20CrMo): Prioritizes hardness (58-62 HRC) for abrasive rock crushing.
RHB175-RHB258 (42CrNiMo): Balances hardness (50-55 HRC) with corrosion resistance for marine or chemical-exposed operations.
Why Material Consistency Matters:
Market hydraulic breakers often mix materials (e.g., cast iron front cylinder + 40Cr piston), causing thermal expansion mismatches that accelerate wear. RAY’s unified 20CrMo/42CrNiMo system ensures matched coefficients, reducing internal stress and extending service intervals.
