Product Details

XCMG Official XR280E Rotary Drilling Rig Machine 94m Depth Hydraulic Crawler Drill Rig

Optimally designed double swing arm luffing mechanism and optimized hinge point position take account of the construction stability and the transportation convenience at the same time.

It adopts H-type hydraulic retractable crawler chassis dedicated for rotary drilling rigs and large-diameter slewing bearing to ensure superior stability and convenient transportation.

It adopts imported Volvo engine with strong power, which effectively reduces fuel consumption and use cost.

The hydraulic system adopts load sensing technology with total power control and limit power control, making the hydraulic system more efficient and energy-saving, independent radiator system provides high heat dissipation efficiency.

The proprietary single-row rope main winch of XCMG effectively solves the twine problem and greatly prolongs the service life of wire rope.

The rotary drive owns normal mode special for soil layers and rock-entering mode special for rock formations, which improves construction efficiency, the autorotation of rotary drive can achieve continuous adjustments of speed in normal mode and rock-entering mode.

Standard centralized lubrication system makes the maintenance more convenient and improves working reliability.
