Reduce horsepower pressure,

improve its life

Drill boom parts

New type drill boom

Drill level ,vertical hole for one fulcrum.

Lower level hole

Hydraulic system

large valve,new flow divider and connect

Smaller resistance and more tidy shape

Sliding carrier parts

Thick and stronger sliding carrier,
