🔧 Key Specifications

🌟 Product Features

• Straight Box Housing: Compact design reduces vibration transfer to excavator boom, extends host machine lifespan.
• Induction-Hardened Piston: Surface hardness HRC 58-62, withstands 100,000+ impact cycles without deformation.
• 100mm Premium Chisel: Made from high-carbon alloy steel, wear-resistant for breaking hard rock, concrete, and asphalt.
• Optimized Hydraulic Circuit: Low oil flow requirement (80-110 L/min) reduces fuel consumption of host excavator.
• Integrated Nitrogen Chamber: Absorbs recoil shock, increases impact force stability, reduces noise by 15% compared to open-type breakers.
• Auto-Lubrication Points: Grease nipples on chisel bushing reduce wear, extend chisel replacement interval to 800-1200 hours.
• Standard Mounting Bracket: Direct bolt-on installation, compatible with most 10-20 ton excavator quick couplers.

🔍 Technology & Principle

The SB50 straight hydraulic breaker operates on a hydraulic-nitrogen combined principle: pressurized hydraulic oil from the excavator’s auxiliary circuit drives the piston to reciprocate at high speed, while the nitrogen chamber cushions the piston’s return stroke, amplifying impact energy transferred to the chisel. Key technologies include:

1. Energy Recovery System: Captures recoil energy from piston impact, reuses it for the next stroke, improving energy efficiency by 20% compared to pure hydraulic breakers.
2. Pressure Compensation Valve: Automatically adjusts oil flow to match material hardness, preventing overloading of the excavator’s hydraulic system.
3. Anti-Blank Firing Design: Stops the piston from striking the chisel when no load is detected, protecting the chisel and piston from damage.
4. Precision Fit Tolerance: Piston-cylinder clearance controlled within ±0.015mm, minimizes internal oil leakage, maintains consistent impact force over time.

🏗️ Applications

• Building Demolition: Breaking concrete walls, foundations, and bridge decks.
• Quarrying & Mining: Secondary breaking of medium-hard rock (limestone, sandstone) after blasting.
• Road Construction: Asphalt pavement removal, concrete road breaking, and trenching in rocky soil.
• Tunnel Engineering: Rock breaking in small to medium tunnel sections, reducing manual labor costs.
• Recycling Projects: Crushing concrete debris for reuse as aggregate material.

🚀 Advantages

1. 25% Faster Breaking Speed: Optimized impact frequency and energy output break the same volume of concrete 25% faster than standard 100mm breakers.
2. 30% Longer Service Life: Premium materials and heat treatment processes extend piston and chisel lifespan by 30% compared to aftermarket alternatives.
3. Low Host Machine Wear: Straight housing design reduces vibration transfer, extending the lifespan of the excavator’s boom and arm.
4. Fuel Savings: Low oil flow requirement reduces excavator fuel consumption by 8-10% during breaking operations.
5. Easy Maintenance: Modular design allows chisel and seal replacement in under 1 hour with basic hand tools.

⚙️ Manufacturing Process

1. Raw Material Selection: High-strength alloy steel (42CrMo) for housing and piston, inspected for composition and internal defects via ultrasonic testing.
2. Precision Forging: Hot forging at 1150-1200°C creates uniform grain structure for housing, improving impact resistance.
3. CNC Machining: 5-axis CNC centers machine piston and cylinder to tolerance within ±0.01mm, ensuring precise fit.
4. Induction Hardening: Piston surface hardened to HRC 58-62, chisel tip hardened to HRC 60-64 for maximum wear resistance.
5. Assembly: Clean-room assembly with torque-controlled fastener tightening, sealed with imported NOKKKK/Nachi seals.
6. Testing: 100% factory testing for impact force, oil leakage, and noise level before shipping.

❓ FAQ

Q: Is this SB50 breaker compatible with my Doosan DX140LC excavator?
A: Yes, the SB50 is compatible with most 10-20 ton excavators including Doosan DX140LC/DX150LC, Cat 315/318, Hitachi ZX130/ZX150, and Komatsu PC130/PC150. Please confirm your excavator’s auxiliary oil flow matches 80-110 L/min.
Q: What type of chisel should I use for breaking hard granite?
A: For hard rock like granite, we recommend the pyramidddd-type chisel, which concentrates impact force on a small area for better penetration. We offer pointed, flat, and pyramidddd chisels as optional accessories.
Q: How often should I grease the chisel bushing?
A: Grease the chisel bushing every 4-5 working hours to reduce wear. Use NLGI #2 lithium-based grease for best results.
Q: What is the lead time for delivery?
A: In-stock units ship within 3-5 business days via air freight. For large orders or custom chisel types, allow 10-15 business days.
Q: Do you offer installation guidance?
A: Yes, we provide detailed installation manuals and remote video support during the mounting process.
