It is a small type of rock drill composed the power machine, working machine and air compress in one. 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. Therefore it changes the traditional working method of rock drill, which was only used to drill blast holes. So it expands functions of rock drill.

YN27T: It is one kind of improved machine on the base of YN27C. Its hand handle is shock absorption, which has certain protective effect for operator.

These three kinds of products have already passed the CE authentication (we are the only one to pass it among the same kind of domestic products) and the No. EZ/2007/90036C.

Auxiliary means:

Moil point, wide chisel, narrow chisel: used for breaking;
Splinting rock tool: used for cleaving rocks;
Spade: used for excavating the frozen and hard earth;
Bended, horseshoe tamping spade: use for tamping roadbed of railway;
Square, round tamping plate: used for small area tamping.
