جهاز حفر دوار فعال ومستقر من طراز XCMG XR320E

Strong rock penetration with high torque, a powerful tool for hard rock construction

320 kN · m torque+330 kN compression, outstanding rock penetration ability, can efficiently cope with moderately weathered/slightly weathered rock layers.
5-speed power head mode (standard/rock entry/energy-saving/high-speed rock entry/high-speed soil throwing), accurately matching the formation.

Multi functional construction method, one machine with multiple uses

Support quick switching between various construction methods such as rotary drilling, CFA long spiral, casing, and down the hole hammer.
CFA mode with automatic grouting and automatic soil cleaning significantly improves the construction efficiency of soft soil layers.
Reserved pipe rolling machine interface, strong construction capability for full casing, suitable for complex strata and deep piles.

Efficient and stable, fast construction, low failure rate

The main winch can lift at a speed of 75 m/min, coupled with high-speed soil throwing, resulting in a hole forming efficiency about 20% higher than other models of the same level.
Large parallelogram amplitude+heavy-duty chassis, strong stability, and not easy to shake during deep hole construction.
Negative flow control of hydraulic system, fast response, precise control, and low fuel consumption.
