Advantages:
• Unique innovation and design : The length of the arm shortened and the weight of the arm increased, changing the proportion of the upper and lower two parts with a new fulcrum and the strength of a powerfull cylinder. All that makes the Mining damage ability of our product much more outstanding than the normal ones. This new product, has been widely used in mining, road construction, housing construction, frozen soil construction and other types of projects.
Efficient:because of its speiciali desigh and itself weight make the excavator have very powerful break forse. can easily break the rock ,the weathering stone.it is much more efficient than breaker hammer.
• Large scale breaking hammer installation:Due to the shortened and heavy arm, the installation of large scale breaking hammer is available. At the same time, the machines are more powerful than the normal ones without any fracture issues.
• High quality: The scientific and reasonable structural design and stable production technology not only shorten the working hours but also reduce the operating cost of the excavator.
