Product Description

Product Description

Rotary drilling rig machine XR220D

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.
* 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.
