economical percussion drilling rig HF-6A

I. Feature and Application

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 our of the hole.

Tubular bit has all kinds of diameters, the hole decides the size and weight of the bit.This tubular bit is very efficient in drilling soil, sand, gravel and rock layer whose hardness is less than 1000kp.

Solid bit has various shapes, but most of the shapes are types.There are all kinds of sizes, the diameter of the hole decides the size and weight of the bit.This solid type bit is hard to break in drilling rock layer whose hardness is more than 1000kp.

The drilling way of percussion rig is to break the rocks into granular slag, though it is not as efficient as core drilling rig or screw drilling rig, but it is irreplaceable, for it can operate in the geological layer when other drilling rigs can not. In short, there is no layers that this kind of drilling rig can not drill, the drill speed depends on the hardness of the working stratums.
