Products Description

1.Percussion type drilling rig is one important drilling equipment in foundation construction of pile and

borehole.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. HF-6A drilling rig isvery 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.
