Model 125 Crawler Breaker Boom System, 14T Class, For Rock/Concrete Demolition

1. Basic Product Information

2. Core Configuration and Performance Features

• Chassis and Travel System: Adopts a Model 154 Komatsu series undercarriage with excellent terrain adaptability, enabling stable travel on muddy and uneven mine surfaces with high passability.
• Work Arm and Breaker: 1900mm boom and 1650mm arm paired with Chuanye (Sino-Korean) cylinders for smooth and powerful operation. The Model 125 hydraulic breaker is matched to system flow of 150-180L/min and working pressure of 16-22MPa, delivering powerful breaking force for efficient crushing of hard rock and thick concrete structures.
• Hydraulic and Power System: Features Rexroth series main pump and main valve paired with a 55KW main pump motor, providing stable power output with max system pressure 24MPa and flow 180L/min. Equipped with high pressure/return filtration, air cooler, and hydraulic oil heater, it adapts to harsh conditions such as high/low temperatures and dusty environments.
• Operation and Control: Hydraulic pilot control offers light operation feel for precise control of breaker impact frequency and position. The ±130° swing angle (360° optional) provides wide 作业 coverage, reducing equipment movements and improving efficiency.

3. Application Scenarios

• Mining: Secondary breaking of rock in open-pit and underground mines, crushing of large ore blocks;
• Construction: Concrete building demolition, foundation breaking, pile head crushing;
• Roads: Old road surface breaking in reconstruction projects, concrete road pile removal;
• Other Scenarios: Demolition operations in confined spaces and factory interiors, areas inaccessible to stationary crushing equipment.

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.
