Adopt imported Cummins turbocharging engine , CE standard .Centralized lubricating system .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.
