XCMG Official XR400E Rotary Drilling Rig for sale

XR400E Rotary Drilling Rig

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.
6、The rotary drive can switch from Nromal 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 low the fuel consumption.
7、Optional configuration according to customers\' requirement, E.g: Crowd winch, Outrigger cylinder, Sleeve-driven and so on.
8、It is equipped with a centralized lubrication system as standard configuration to provide more convenient maintenance and make the machine a good reliability .
