Huilian 28-35 Ton Excavator Hydraulic Rock Breaker SB121 for SOOSAN

Hydraulic breakers (also known as hydraulic hammers or rock breakers), commonly attached to excavators, are widely used across multiple industries due to their high-impact force and versatility. Key application areas include:

1. Construction & Demolition

   • Demolishing concrete structures, foundations, and walls.

   • Breaking reinforced concrete during building renovations or site clearance.

   •  

2. Mining & Quarrying

   • Fragmenting oversized rocks or boulders in quarries.

   • Secondary rock breaking in mining operations to facilitate material handling.

   •  

3. Road & Infrastructure Development

   • Crushing asphalt or concrete pavements for road repairs.

   • Trenching and bedrock excavation for utility installations (e.g., pipelines, cables).

   •  

4. Municipal Engineering

   • Breaking frozen ground or ice in cold regions.

   • Maintaining drainage systems and urban infrastructure.

   •  

5. Metallurgy & Recycling

   • Processing scrap metal, slag, or industrial waste.

   • Dismantling heavy machinery or steel structures.

   •  

6. Agriculture & Landscaping

   • Clearing rocky terrain for farmland expansion.

   • Creating drainage channels or reshaping landscapes.

   •  

7. Disaster Response

   • Emergency demolition of collapsed buildings post-earthquakes or floods.

   • Clearing debris-blocked roads or access points.

These tools excel in environments requiring precision, high power-to-weight ratio, and adaptability to tough materials like rock, concrete, or asphalt. They are essential for improving efficiency in heavy-duty operations while reducing manual labor and operational costs.

Here’s the hydraulic breaker maintenance guide, organized step-by-step for clarity:

1. Pre-Operation Daily Checks

1. Fastener Inspection

   • Check for loose components such as the chisel tool, bolts, and guard plates, especially high-vibration areas (e.g., side bolts, accumulator bolts).

   • Tighten immediately if loosening is detected to prevent part detachment or damage.

2. Hydraulic System Check

   • Inspect hydraulic hoses and joints for leaks or wear. Replace aged hoses promptly.

   • Ensure hydraulic oil cleanliness meets standards (recommended: ISO 18/15 grade or higher) and maintain proper oil levels.

3. Chisel Tool and Lubrication

   • Inspect the chisel tool for wear, bending, or cracks. Replace severely damaged tools.

   • Apply grease (e.g., lithium-based grease) to the chisel shank before each use to reduce friction.

2. Operational Best Practices

1. Lubrication During Work

   • Lubricate critical points (e.g. piston and cylinder contact areas) with specialized grease every 2 hours

   • Increase lubrication frequency in dusty environments to prevent contamination.

2. Avoid Dry Firing and Overloading

   • Never operate the breaker without proper material contact ("dry firing"), as this damages internal components.

   • Limit continuous operation to 1 hour per session to prevent hydraulic system overheating.

3. Proper Operating Posture

   • Keep the chisel perpendicular to the working surface to avoid uneven wear or piston damage.

   • Maintain firm chisel contact with the material to minimize energy rebound.

3. Post-Operation Maintenance

1. Cleaning and Pressure Relief

   • Clean the breaker’s exterior after shutdown to remove debris and prevent hydraulic system contamination.

   • Release residual hydraulic pressure via the control valve before shutting down to protect seals.

2. Nitrogen Chamber Inspection (Critical)

   • Regularly check nitrogen pressure in the accumulator (typically 1.4–1.6 MPa; refer to the manual). Recharge if pressure is low.

   • • Test nitrogen pressure every 500 hours or monthly using specialized inflation tools.

3. Long-Term Storage Protocol

   • Retract the chisel fully and apply anti-rust oil to exposed metal surfaces.

   • Store in a dry environment to prevent hydraulic oil emulsification.

4. Scheduled Professional Maintenance

1. Hydraulic Oil Replacement

   • Replace hydraulic oil every 500 hours, and clean the tank and filters simultaneously.

   • Use manufacturer-approved oil to avoid compatibility issues.

2. Seal and Wear Part Replacement

   • Inspect seals, pistons, and bushings every 1,000 hours. Replace worn parts immediately.

   • Prioritize genuine OEM components for durability.

3. Professional Calibration

   • Schedule annual inspections by certified technicians to verify structural integrity and performance.

Key Reminders

• Always follow the manufacturer’s guidelines for specific models.

• Document maintenance activities to track wear patterns and optimize service intervals.

• Address abnormal noises or performance drops promptly to prevent major failures.

This structured approach ensures extended service life and safe, efficient operation of hydraulic breakers.
