Instruction

The rock drill is a kind of high efficiency air leg rock drill machine.It is widely used for blasting holes and other drilling projects in a quarries, railway construction, water conservancy construction and defence project facility.

It is suitable for drill level or gradient holes in medium hard or hard rock(f=8-18).The drilling depth can be five-eight meters. It can be matched with the FT140BD short air-leg or FT140B long air-leg to use in the basis of the width of rock.Also it can be fixed on drilling-vehicle or drilling-shelf.

To ensure the well lubricating.This rock drill may match FY200B oil reservior .
