1. Basic Product Information

2. Core Configuration and Performance Features

• Heavy-Duty Breaking System: The DEHN140 Soosan series triangular hammer with a Φ140mm chisel and impact frequency of 460~780bpm adapts to 16~25MPa working pressure, delivering powerful breaking force for efficient crushing of hard rock and thick concrete, with far higher efficiency than traditional small breakers.
• Large Radius Work Arm: 2100mm boom and 1850mm arm with a maximum working radius of 10.3 meters and vertical breaking height of 5.5 meters, suitable for large-span and deep foundation demolition operations, reducing equipment movements.
• Hydraulic and Power System: Rexroth series main pump and main valve paired with a 55KW main pump motor (diesel engine optional for dual power), providing powerful and stable power output with max system pressure 28MPa and flow 200L/min. Equipped with a 0.8KW air cooler and 3KW hydraulic oil heater, it adapts to harsh conditions such as high/low temperatures and dusty environments.
• Chassis and Control: Komatsu series undercarriage with excellent terrain adaptability for stable travel on muddy and uneven mine surfaces. Hydraulic pilot control offers light operation feel for precise control of breaker impact frequency and position, with wide 作业 coverage.

3. Application Scenarios

• Mining: Secondary crushing of hard rock in open-pit mines and large ore blocks in underground mines;
• Tunneling: Hard rock crushing in tunnel boring, roadway widening, and rock trimming before support;
• Construction: Large concrete building demolition, thick foundation breaking, and pile head crushing;
• Roads: Old road surface removal and subgrade hard rock excavation in reconstruction projects;
• Other Scenarios: Heavy-duty demolition operations in confined spaces and factory interiors.

4. Operation and Maintenance Recommendations

• Inspect crawler tension, hydraulic oil level, and temperature before operation; grease the breaker chisel.
• Stabilize the equipment during breaking to avoid tipping from one-sided forces; never dry-fire the breaker.
• Regularly replace hydraulic oil and filters, and inspect hydraulic hoses for wear to prevent leaks.
• Preheat the hydraulic oil with the heater before operation in cold weather, and start the breaker only when the oil temperature is normal.
• Regularly inspect the wear of the breaker chisel and replace it promptly to maintain breaking efficiency.
