Hydraulic crawler drill is an indispensable core equipment in contemporary geotechnical engineering and geological exploration. The equipment combines the strong power of hydraulic drive and the good passability of crawler chassis, which is suitable for mineral exploration, water well drilling and tunneling pre-tunneling geological prediction and other multi-scenario operations in complex terrain.

Advantages of Hydraulic Crawler Core Drilling Rig
Compared with traditional mechanical drilling rigs, hydraulic crawler drilling rig has several significant advantages.
- The hydraulic transmission system makes the torque output more stable, the drilling process more stable, and it is not easy to appear the phenomenon of “jump drilling”.
- Crawler chassis, steel crawler board (rubber block can be inserted separately). The hydraulic motor drives the built-in walking reducer to realize walking, especially suitable for mountainous areas, hills, forests and other complex working conditions.
- The automatic rope coring function simplifies the process of drilling tool replacement, improves operational efficiency and reduces labor input.
- The whole machine is easy to maintain, with good versatility of hydraulic components, low failure rate, and lower maintenance cost.
In South America, Africa and other markets, customers generally favor the stable performance and sustainable operation ability of this kind of drilling rig.

Rope Coring Workflow
Rope coring is an important process in modern core drilling, and the process includes: lowering the drilling tool – drilling to the design depth – releasing the inner pipe – starting the drill for coring –Re-lower the pipe and continue drilling.
YG hydraulic crawler drill can shorten the time of separating the inner and outer tubes and improve the coring efficiency through the special release mechanism. This process is especially suitable for deep hole core drilling, which can reduce the number of drilling operations and labor intensity.


How to Match the Drilling Tools for Rope Coring?
Reasonable selection of drilling tools for rope coring is very important, YG recommends to choose HQ, NQ, PQ series drill pipes and bits according to different geological conditions.
Generally speaking, a larger diameter (e.g. PQ) is used for soft rock formations, while NQ is used for hard rock formations to balance the drilling speed and coring rate. Special formations also need to be equipped with anti-jamming drilling tools, drill pipe joint protectors, etc. to ensure drilling safety.
