 7655-type air-leg rock drill is a highly efficient drilling machines. It is widely used in rock roadway and a variety of drilling blast hole drilling operations, is the mining, railway, transport, water conservancy construction and other important equipment in rock engineering. Wider use of the machine, the most suitable medium hard or hard (f = 8 ~ 18) rock horizontal or inclined drilling horizontal or inclined direction of the hole, drilling depth of up to 5 meters. This machine not only can the size and FT1160A roadway short air leg or FT160B type Long-legs supporting the use of gas can also be installed in the car or drill rack drill work. To ensure good lubrication, the machine is equipped with FY200A type oiler. Structural characteristics of the machine is equipped with gas in the form bowl valve used, reasonable structure, flexible start. And a light weight, drilling speed, low air consumption, little vibration, easy operation, low failure rate, parts, long life, and good economic returns.
