Factory Cheap Rc Skid Steer - XCMG Rotary Drilling Rig XR220D – Chengong Detail:
Detailed configuration
Adopt imported Cummins turbocharging engine ,
CE standard .Centralized lubricating system .
Advantages
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.
* 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.
* 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.
