Description

XR400E rotary drilling rig is widely applied in pore-forming work of the cast-in-place concrete pile in construction of foundation works, such as highways, railways, bridges, ports and high-rise buildings.
1.The luffer is designed to double-boom style to provide extraordinary stability and transport convenience whose hinge joint has been majorized.
2.It adopts the H-style dedicated hydraulic retractable crawler chassis and large diameter slewing bearing to provide extraordinary stability and transport convenience;
3.Imported Cummins electric control turbo-supercharged with three gears engine is used, it has strong power. According to specific working conditions, the users can select a corresponding gear of the engine, getting the drilling rig working as three engine.
4.The main hydraulic system adopts the negative flow control, and adopts the main power control and limit power control together which can increase the system efficiency and make the most of the engine power. It adopt three-in-one colling system which is tightly packed and has a high-efficiency in cooling.
5.It adopt the single-rope for main winch to figure out the wear of the steel rope, and extend the life-span.
