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. Main and assistant windlass are arranged on turn table to improve its overall stability. Comprehensive numerical control slewing platform combined with parallelogram amplitude varying device makes boring tool position rapidly and accurately. Drilling depth and single drilling footage can automatically measure and display. A new drilling mast auto-adjusting electric control system not only control drilling masts working position but also control its rising-and-falling process. Unique assistant windlass mechanism improves systems working efficiency,guarantees accuracy of drilling depth measuring, and makes mast rising-and-falling process smooth and fluent.
