Basic Info.
Product Description
Features:
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: * The machine adapt 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 engine with European III effluent standard. Meet environmental rotection 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 anticontored, therefore the drill accuracy is heightened.
* The complete machine has passed CE certification of TuV Rheinland group.
* Standard centralized lubricating system, allowing easier maintenance.
