Xugong XR400E rotary drilling rig helps the United States

Recently, Xugong XR400E rotary drilling rig entered Linyi (formerly known as 琅琊), and carried out the Beijing-Shanghai high-speed railway reconstruction and expansion project. The products show its strong construction performance, and are highly recognized and praised by customers: the big country heavy equipment helps the beautiful Linyi, to force!

Linyi, known in ancient times as “琅琊”, is an important city in Shandong Province, a transportation hub, an old revolutionary base, a long-standing culture, and a huge potential for economic development. At present, many projects are under construction, and the demand for construction machinery is huge.

In the Lunan area where Linyi is located, the geological conditions are very complicated, the rock hardness is as high as 80Mpa or more, and the pile foundation construction is extremely difficult. Other domestic brands of similar products are unable to enter the hard rock construction and have low construction efficiency. As the representative product of Xugong E series rotary drilling rig, XR400E is a large-tonnage model specially developed by Xugong Foundation for hard rock formations. The XR400E has attracted much attention since its launch. After comparing the construction performance of the rigs at home and abroad, the customer finally chose the XCXX XR400E, a “rock attack weapon”.

Xugong XR400E entered the Lunan hard rock construction market, showing not only the strength of Xugong rotary drilling rig as the industry's “single champion”, but also its own characteristics and advantages.

1. It adopts double-acting arm luffing mechanism and special H-type hydraulic telescopic crawler chassis for rotary drilling rig. It is equipped with large-diameter slewing ring to ensure superior stability and convenient transportation.

2. With Cummins engine, it has strong power and has three-speed power control. Users can select the corresponding gear according to working conditions, realize the function of one rig to play three engines, optimize the three-speed power curve, effectively reduce fuel consumption and use. cost.

3. The hydraulic system adopts load sensing technology, superimposing total power control and limit power control technology, making the hydraulic system more efficient and more energy efficient.

4. Xugong's proprietary single-row rope main hoisting structure effectively solves the problem of wire rope “biting rope” and greatly extends the service life of the wire rope.

5. The power head has the common mode, the rock entering mode and the energy saving mode. The user can select the corresponding mode according to different geological conditions, which improves the construction efficiency and reduces the fuel consumption.

6. A variety of configurations: optional winch pressure, casing drive, etc., good scalability.

7. Standard centralized lubrication system, more convenient maintenance and improved work reliability.
