1 Used for general investigation, geophysical exploration, high-way and building construction, and blast-hole drilling etc.
2 With hydro-automatic feeding device, and high drilling efficiency.
3 Designed with hydro-chucking unit instead of slips to ensure drilling from stop when changing pipes.
4 Close levers, convenient to operate, safe and reliable operations.
5 Compact in structure. All the drill, water pump and diesel engine installed on one base frame result in space-saving.
6 Light in weight, easy disassembling for transportation and applicable to working
