Efficient construction: With 2.2-meter large-diameter construction capability, working efficiency is much higher than other similar models by increasing main winch speed by 12%; adopting the sixthgeneration new material 445 Kelly bar, integrated locking device, whole strength increased by 25%, suitable for drilling in multiple strata.
Strong power: Imported large-displacement EFI engine, equipped with high-power main pump, using power optimization control technology, real-time power distribution, fast response speed, high fuel efficiency, saving energy by 10%~15%.
Step drum: Single layer wire rope winding for interlocking Kelly bar; free of mutual extrusion and wear to increase service life by 35%.

High reliability: High standard design for mast and luffing boom to make it more strong and durable, no cracking in 20,000 hours
operation test. High configuration reducer with large torque reservation and wide safe high-efficiency working scope.
Intelligent upgrade: HD touch screen, 3ms refresh frequency, smooth animation display.
Convenient maintenance: The rotary head inside driving key outside connected by bolts for easy observation and replacement; the main winch wire rope end is fixed by wedge easy to disassemble and assemble. The special lubrication point connected with outlet hose to facilitate butter injection.
