Breaker for digger is a device specially designed for breaking operations. Its power comes from the pressure oil provided by the pump station of an excavator or loader. It can efficiently clean floating stones and mud in rock gaps during the excavation of building foundations. When choosing a rock breaker hammer, it is necessary to match the most suitable equipment according to the excavator model and working environment.

Different models of equipment vary in impact frequency, impact force, and the tonnage of suitable excavators. They can precisely match various operation requirements. This parameter table helps you choose according to actual scenarios. For light breaking scenarios, small equipment (such as YG350, suitable for 0.5 – 1 ton carrier weight) is more flexible; for heavy-duty operations like breaking hard rocks, large equipment (such as YG2100, suitable for 60 – 80 ton carrier weight) can handle efficiently.
Working Principle of Breaker for Digger


The hydraulic breaker attachment is mainly composed of a hammer body (movement) and a bracket. The upper and lower splints protect the movement respectively, and the hammer body directly contacts the broken materials. Among them, the accumulator plays a buffer and protection role and can prolong the service life of the equipment (equipment with a small size or diameter less than 10 cm is usually not equipped with it). It is driven by hydrostatic pressure: the oil pressure pushes the piston to move upward and compresses nitrogen at the same time, making the piston hit the chisel rod at a high speed and do reciprocating motion, and finally realizing the breaking of solids such as ore and concrete. This design makes it more stable and efficient in operation.
Product Advantages of Rock Breaker Hammer
- Optimized design for higher efficiency: Adopt the most optimized design concept, increase the stroke of the piston and cylinder block, and make the diameter of the piston the same as that of the drill rod, ensuring the best matching between the breaker for digger and the host machine. It can reasonably utilize the highest output energy, save energy, and improve work efficiency at the same time.
- High-quality materials and precision technology: Use high-quality materials and be processed by special precision technology. Core components such as pistons, main body bolts, and oil cylinders have all passed strict quality inspection, ensuring the highest quality of the equipment and prolonging the service life.
- Reliable, durable, and cost-effective: As a cost – effective equipment, its durability reduces the maintenance frequency, and long-term use can reduce operation costs. Whether it is small-scale maintenance or large-scale projects, it can perform stably.
Application Scenarios of Breaker for Digger



- Mining field: Can be used for mountain opening, mining, grid screen breaking, and secondary breaking, and can easily deal with hard ores and rocks.
- Metallurgical industry: Suitable for ladle cleaning, slag treatment, furnace demolition, and equipment foundation removal, helping to carry out metallurgical operations efficiently.
- Railway engineering: Plays an important role in mountain opening, tunnel excavation, road and bridge demolition, and subgrade compaction, ensuring the progress of railway construction.
