Xr280e Bore Pile Foundation Rotary Drill Rig
XCMG Factory XR280E Bore Pile Foundation Rotary Drill Rig for Sale
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.
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.
