With a large diameter、Construction demand of ultra-deep rock pile foundation increases

The market of big bore rotary drilling rig is surging.

ZR550GType rotary drilling rig“Tiger”The posture breaks in

What is its hard power?？

 

Zhu Changlin, Director of Rotary Drilling Rig Product Research Institute

“The borehole is deep and thick.，Strong ability to tackle key problems”

Stable、Strong is“Hard skills”！

▶ Front lying structure，Double stable：Oversize self-weight combined double-triangle front-lying structures，Double the stability；Output is stable，Not afraid of boulders，Rocking is faster.；

▶ Efficient rock entry。Equipped with large-displacement power head motor、High flow pumps and valves，Power head with high torque and high speed，Dynamic matching technology of limit torque is adopted.，Surging performance，The rock entering ability is stronger.；Powerful main winch lifting capability，Safe、Efficient；

▶ Reliable consumption reduction。First-line core brand parts，New Generation of China IV Cummins Engine，And that reliability is high；Better matching between engine and hydraulic system of international famous brand，The fuel consumption of the whole machine is 10% lower than that of the products of the same level%Above；Wire rope single layer design，Significantly improve service life；Multiple modes can be switched freely，Deal with different working conditions at will。
