ZYL-7000D(B) tracked full hydraulic integrated type DDR for coal mine

The ZYL-7000D fully hydraulic crawler directional drilling rig (DDR) for coal mines is a fully hydraulic-driven, integrated-type, all directional crawler DDR. It stands as an upgraded version of ZYL-6000D(A) and ZYL-6000D(B) and boasts the following characteristics:

1.The drilling rig has a high torque and a reasonable speed range, making it well-suited for both small-diameter diamond core drilling and fulfilling the requirements of large-diameter hard alloy core drilling and a variety of engineering drilling applications;

2.The drilling rig exhibits impressive feed and pulling capabilities, making it proficient in handling unique scenarios encountered within boreholes;

3.The drilling rig features an uncomplicated structure, a well-thought-out layout, small overall dimensions, and high transmission efficiency;

4.The operation of the drilling rig is centralized, straightforward, and convenient, offering flexible and reliable control while significantly reducing labor intensity;

5.The drilling rig is able to mobilize itself as a single unit, facilitating a convenient and swift installation process, ultimately leading to a substantial reduction in preparation time;

6. The large-torque drill rig can expand holes up to a maximum diameter of 153mm, leading to a substantial improvement in gas extraction efficiency.
