Product Description

Factory New Designed XR280D Mobile Diesel Rotary Drilling Rig with High Efficiency


 

XR280D Rotary Drilling Rig widely used in boring operation of bored concrete pile in foundation engineering of highway, railways, bridges, ports, docks and high-rise buildings.

 

 

Performance Characteristics:

* The special hydraulic chassis for the rotating drill with extensible crawler is provided with the excellent stability and is convenient to transport. The imported turbo-supercharged engine(meeting EU-III standard) is powerful, and has sufficient power reserve, which can be operated in plateau. Its noise and emission meet the national standards. The constant power and the best output enable the complete machine to function at its best.

 

 

* The patented parallelogram articulation mechanism can work in a large area. The drill mast, which is designed in box structure and made of the materials with high strength, has good rigidityand anti-distortion, guaranteeing the drilling accuracy. The hinge is provided with the bearing exempt from lubrication, and can work freely. The slag can be discharged in any angle due to 360 degree lifting and revolving.

 

 

* The intellectual controlling system, with self-intellectual property right are used, including the automatic and manual regulation of the perpendicularity of the drill mast, automatic display of the drilling depth, automatic rotation positioning control, and intellectual fault diagnosis control.

 

 

* The machine adapt single row rope for main winch to figure out the wear of steel rope. extend the life-span and high reliability.

 

 

* With infrared camera for observing main winch, manipulator can observe the state of steel rope at day and night in cab.
