China Rotary Drilling Rig

Advantages: 1.Double motor high-low speed power head ensures efficient drilling-in.etc 2.CCC/CE ISO Certification

The rotary drilling rig Technical advantages: Efficient and energy-saving engine limit power regulating system supplies strong power.

Double motor high-low speed power head ensures efficient drilling-in. Frictional and interlocking drilling rod are equipped with all kinds of slewing bucket and short or long optional helical bore and have drilling rod auto-assemble function.

Retractable caterpillar chassis facilitates improving drilling works stability and reducing transport width. Self-spelling folding drilling mast can realize conversion between working and transport condition without employing external force.
