1)Safe and stable traving system 2)Powerful and reliable engine 3)Rotating system
MAIN FEATURE
1. High efficient pore-forming equipment for the 150mm diameter pile foundation engineering, equipped with Φ508 drill stem reaching 55m in drilling depth. 2. Adopting advanced OEM Caterpillar rotary drilling rig chassis with extensible bottom track roller frame; meeting the requirements of road transportation laws and regulations on whole machine width and also improving the machine’s working reliability and stability.3. Caterpillar electrojet turbo charging inter-cooling engine is high in reliability, economical in oil consumption and superior in reserve power. The load is sensed by computer and the fuel charge under the control of direct-injection electrical controlled oil spout, ensuring strong power and economical oil consumption.4. Taking CAT hydraulic circuit as platform, the main hydraulic circuit adopts gross power control, sub-power control, and negative flow control; the supplementary hydraulic circuit adopts most advanced load sensitive control technology of international engineering machinery, realizing the optimal match of hydraulic pump output power with loading of various moving parts and improving the working efficiency and controllability of the system.5. The main winch and power head adopt multiple main valves for confluence control, maximally reducing on-way resistance and improving working efficiency. The main winch and power head adopt double-circuit control for compound control action to ensure the separate control, improving the ability of drillers dealing with complicate conditions.6. The box-type structure is adopted. The reinforced built-in clapboard with strong rigidity and good stability ensures twisting strength and bending resistance. The whole mast is of four-section hinge joint and three-section folding type, minimizing the overall dimension of the whole machine and convenient for transportation.7. The main winch is fixed on the upper frame instead of mast, avoiding easy rollover and extending the service life of steel wire.8. The universal drilling bucket, short spiral drill bucket, separate drilling bucket and cylindrical rock drill are available to meet the needs of various geologies, such as hardpan, gravel, pebble bed, medium decomposed rock, and mud stone.9. Especially for engineering, 10.4inch true color display displays all performing parameters; real-time automatic fault diagnosis, convenient for inquiry; the friendly interface of working parameter setting and real-time help system is simple and convenient for operation.10. Adopting advanced CAN-Bus control technology to comprehensively control the engine, hydraulic pump and hydraulic valve and supervise the operating conditions of various moving parts for the whole range to ensure the high reliability and intellectualization of the whole machine. All the key components adopt the world famous products.
