It is powered by the small gasoline engine and used for drilling on the hard rock or rock with medium hardness. Because it is self-powered, it is especially convenient to be used for projects without other power supply, or projects that are inconvenient for conveying the large-volume unit, or for mobile construction projects.

The shell is made of the magnesium alloy compression casting and has smart weight. Ignition system: controllable silicon, contactless system.

YN27C YN27T: It has the independent impact function. It can be used for cleaving rock, bruising the concrete foundation,  tamping the railroad bed, small area tamping by combining with auxiliary means.
