Introduction of 7655 air leg rock drill

The 7655 air leg rock drill is a highly efficient rock drill. It is widely used in rock tunnel excavation and various rock drilling operations to drill blast holes. It is an important machine tool in stone works such as mines, railways, transportation, and water conservancy construction.

The 7655 air leg rock drill has a wide range of applications. It is most suitable for drilling horizontal or inclined horizontal or inclined blast holes on medium-hard or hard (f=8~18) rocks. The drilling depth can reach 5 meters. This machine can be used with FT160A short air leg or FT160B long air leg according to the size of the roadway section, or it can be installed on a drill carriage or drill frame to work. To ensure good lubrication, the machine is equipped with a FY200A oil injector.

Structural features: The air leg rock drill adopts a bowl-shaped gas valve, which is reasonable in structure and flexible to start. And it has the advantages of light weight, fast rock drilling speed, low air consumption, low vibration, convenient operation, low failure rate, long life of parts, and good economic benefits.
