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