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.
Technical Characteristics:
1.The machine adapt single row rope for main winch to figure out the wear of steel rope. and extend the life-span.
2.With infrared camera for observing main winch, Manipulator can observe the state of steel rope at day and night in cab.
3.Optional configuration according to customers' requirement Excellent expansibility.
4.dopting the imported supercharged Imported engine with European III effluent standard. Meet environmental rotection and energy conservation.
5.With the hydraulic pressure system adopted threshold power control and positive flow control, the system acquired high efficiency and higher energy conservation.
6.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 anticontored, therefore the drill accuracy is heightened.
7.The complete machine has passed CE certification of TuV Rheinland group.
8.Standard centralized lubricating system, allowing easier maintenance.
