جديد وحدة حفر الآبار XCMG XR178E

With a maximum output torque of 178kN·m and a maximum speed of 38 r/min, the rotary drive can work more efficiently.
The double jib parallelogram luffing mechanism has a large support angle and a 24% increase in support range, which makes the operation more stable.
Cummins electronically controlled turbocharged engine has strong power and higher fuel adaptability, making the service convenient and efficient.
The main hydraulic system adopts negative flow control technology and large displacement main pump with low speed engine, which has lower fuel consumption and higher efficiency.
The intelligent control system realizes automatic adjustment & display of mast verticality, automatic soil shake-off, automatic forward & reverse rotation of rotary drive for spin-off, and ground-touching protection, making the whole machine more intelligent and the operation more convenient and safer.
With a large diameter slewing bearing, the TDP series hydraulic crawler chassis dictated for rotary drilling rigs ensures better working stability.
The whole machine can be transported without removing Kelly bar, which is convenient and efficient.
Convenient maintenance: optional centralized lubrication system; The pump, valve and filter element are concentrated near the side door, and the maintenance space is large. Online fault alarm diagnosis, guide troubleshooting; Online fault warning, guide customer investigation in advance, prevent problems before they happen.
