EXL method

The self-propelled full rotation drilling machine "Excel Method" demonstrates the unique mobility of self-propelled machines. Additionally, compared to the currently mainstream stationary drilling machines, it has a casing rotation speed that is about 1.5 times faster and a casing lift stroke that is three times greater, allowing for faster drilling speeds and the ability to easily cut through hard gravel and rock. There is no need to lift the machine body, so large cranes are not required.
