1.Simple Description of borehole drilling equipment:

1>Percussion type piling 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 borehole 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.
