XCMG 2021 year Used Rotary Drilling Rig XR400E Price
It adopts double-boom luffer and H-style. Dedicated hydraulic retractable crawler chassis and large diameter slewing bearing to provide extraordinary stability and transport convenience.
According to specific working conditions, the users can select a corresponding gear of the engine, getting the drilling rig working as three engines.
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 cooling system which is tightly packed and has a high-efficiency in cooling.
It adopts the single-rope for main winch to figure out the wear of the steel rope, and extend the life-span.
The rotary drive can switch from Normal Mode, Rock Mode and Energy-Saving Mode, the user can select a corresponding mode of the rotary drive according to the specific working conditions, which can greatly improve the working efficiency and lower the fuel consumption.
It is equipped with a centralized lubrication system as standard configuration to provide more convenient maintenance and make the machine a good reliability.
