Deep Rock Well Drilling Rig

Nowadays, with the uneven distribution of water resources around the world, deep rock well drilling has become an effective means of obtaining groundwater in many mountainous, rural and arid areas. Especially in areas with hard geology and deep groundwater, choosing a high-performance deep rock well drilling rig is crucial for drilling efficiency and cost control.

As a professional construction machinery manufacturer in China, YG Machinery has launched the YG-400 model drilling rig, which has become one of the most popular medium and deep rock well drilling rigs among overseas customers due to its strong penetrating power and stable operational performance.

Why Choose a Deep Rock Drilling Rig?

Compared with shallow soil, the rock structure is much harder, and the common geology of sandstone, granite, shale, etc. requires extremely high power and torque for the equipment. Ordinary drilling rigs can hardly cope with this, and are prone to problems such as jamming, low efficiency and long time consuming.

And deep rock well drilling rig is specially designed for rock geology with the following features:

1. Strong torque and high power, which can efficiently penetrate hard strata;
2. With the operation of submerged hammer, the speed is fast and the drilling is stable;
3. suitable for 200m~600m deep well operation, meeting the needs of rural water supply, farm irrigation, geothermal drilling and so on.

The Key to Reduce the Cost of Deep Water Well Drilling: Equipment Selection

In traditional construction, deep water well projects often have high costs due to complex geology and long construction periods. And choosing the right deep rock well drilling rig can effectively reduce labor, fuel consumption, maintenance costs, and then control deep water well drilling cost.

How YG-400 can help you save cost:

1. Fast drilling speed: the average efficiency of penetrating rock formation is increased by 35%, saving operation time;
2. Low maintenance: solid structure, easy to replace wearing parts, reduce downtime;
3. High cost-effective: the price is much lower than European and American brands, and the performance is comparable to imported drilling rigs;
4. One-stop service: support video teaching, remote guidance, global delivery.

Customer Case Snapshot (Peru)

In early 2025, an engineer customer in Peru purchased YG-400 for a mountainous water supply project. Facing the environment of large rock thickness and strong terrain undulation, YG-400 successfully drilled a 370-meter deep well, and the whole construction took only 7 days, with stable water output from the drilled well, and the customer highly recognized the stability and cost-effectiveness of the equipment.

“Compared with local equipment and European and American brands, YG machine not only produces water fast, but also has a very reasonable price, which greatly reduces our deep well drilling cost.”-Customer Comments
