product Introduction
HF-6A+ percussion drilling rig is one of the most important drilling machine in the piling foundation and bore hole drilling. It can adapt various geological condition, especially for drilling hole in gravel and rock with strong adaptation. Meantime, percussion drilling rig has high pore forming efficiency and good pile formation quality. HF-6A 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, gravel or rock into pieces, and then use the slag tube or mud pump to clean the slag out of the hole.
Application
The drilling rig is mainly used in pile driving for photovoltaic Solar power station , pile driving for Highway guardrail, highway guardrail construction engineering construction, etc.
