The ZYL-17000D(D) fully hydraulic crawler directional drilling rig (DDR) for coal mines is a fully hydraulic-driven, all directional crawler DDR. It 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.Leveraging patented cylinder technology, the drilling rig showcases a smaller overall length, an extended cylinder stroke, and zero unused space behind the power head. Through a single cylinder feed, it is possible to achieve uninterrupted drilling of 1.2m, which reduces the need for rod changes and substantially improves productivity.

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

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

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

6.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;

7.The large-torque drill rig can expand holes up to a maximum diameter of 256mm, leading to a substantial improvement in gas extraction efficiency.
