1. The excavator breaker has a reasonable design and simple structure, reducing wearing parts.

2. Piston: It uses special heat-treated high-strength materials and uses super grinding equipment for surface treatment, which effectively reduces the occurrence of roughening on the piston surface and ensures a long service life.

3. Shell reinforcement: For harsh working conditions, key parts have been strengthened in design to improve durability and reliability; the diameter of the bolts has been increased by 10%, and all tensile tests have been conducted to greatly improve the strength.

4. Precision fit: The gap between the piston and the cylinder is 0.02-0.03mm. The precision fit prevents internal leakage of hydraulic oil and effectively protects the excavator.

5. Accumulator: stores hydraulic energy to increase impact force; absorbs hydraulic vibration and fluctuations and reduces oil circuit pulses.

6. Directional valve: It adopts precision processing technology to reduce pressure pulses and focus on protecting the excavator hydraulic system.

7. The excavator's breaker hammer has strong impact: the perfect product design ensures strong impact. For example, the piston stroke is increased, accumulators are equipped for 20T and above, and hydraulic oil pressure and nitrogen pressure are perfectly matched.
