XCMG Official 76ton Rotary Drilling Rig Machine XR220D.

XR Series Rotary Drilling Rig stands for our company's achievement in many years' development and researches on piling machine, adopting the advanced technology, both at home and abroad. With our company's powerful machinery manufacturing capacity, it is specially designed to drill the pile hole with the big diameter and into hard—layers, fitting for layer conditions in most areas. 

XCMG XR220D 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 machine adopts single row rope for main winch to figure out the wear of steel rope. and extend the life-span.

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

* Optional configuration according to customers' requirement Excellent expansibility.

* Adopting the imported supercharged CUMMINS engine with European III effluent standard. Meet environmental protection and energy conservation.

* With the hydraulic pressure system adopted threshold power control and positive flow control, the system acquired high efficiency and higher energy conservation.

* The patented parallelogram articulated structure actualizes a wider work range. The highly strengthened box-type steel structure design makes the mast of highly-rigidity and anti-contored, therefore the drill accuracy is heightened.

* The complete machine has passed CE certification of TuV Rheinland group.
