It can adopt to various geological conditions, especially to pebble bed and rock stratum. Percussion drilling rig is more applicable than the other kinds of drilling machines. Meanwhile, when use the percussion drilling rig to drill boreholes, after the hole is formed, there will be a dense layer of soil around the hole wall, which is very useful for stabilizing the hold wall and improving the carrying capacity of the pile foundation. 2) YF-XH-8A drilling rig is very popular in the market currently, all of its components are all installed in the trailer, like electric motor, drive motor, hoist, mast etc., integrate motion. The percussion drilling rig uses the crank link mechanism to change the power's gyration motion into alternating motion,through the steel wire rope to drive the hammer bit to do up-and down motion. With the impact effect of the hammer bit's free failing, to break the soil, sand, pebble or rock into pieces, and then use the slag tube or mud pump to clean the slag our of the hole.
