In infrastructure projects such as pile foundations, geological exploration, and farmland irrigation, the efficiency of drilling in complex terrain has always been a core factor affecting the construction period. Ordinary wheeled equipment has poor off-road capability, and dedicated pile drivers have limited functionality, making it difficult to meet the needs of multiple construction scenarios. Crawler rotary drilling rigs, with their strong mobility, adaptability to various geological formations, and versatility, have become the main equipment for small and medium-sized construction teams and are the fastest-growing segment in the general-purpose rotary drilling rig category.
Crawler rotary drilling rigs, also known in the industry as tracked fully hydraulic rotary drilling rigs, tracked rotary drilling rigs, or foundation exploration drilling rigs, are complete drilling equipment that relies on a tracked chassis for movement and uses a fully hydraulically driven rotary drilling tool for cutting. Their core functions include pile foundation drilling, geological exploration sampling, water well drilling, and anchor bolt drilling. Changing different drilling tools allows for switching between construction scenarios, making them multi-functional rotary foundation drill rigs.
As the original manufacturer, YG offers not only its main tracked models but also 4-wheel rotary drilling rigs and various piling machines. We can recommend the most suitable equipment based on your construction scenario and geological conditions, eliminating the need to pay extra for additional features. Currently, this series of equipment has been sold in bulk to countries with rapid infrastructure and mining development, such as Indonesia, Ghana, Peru, Malaysia, and South Africa, and is widely adaptable to various geological formations, including soft soil, sand, weathered rock, and medium-hard rock.

What Are the Core Functions of a Tracked Rotary Drilling Rig?
- High torque drilling capability. The YG rotary drilling rig’s power head has a maximum output torque ranging from 46-120 KN · m, easily handling various strata from soft soil to moderately weathered rock. The intelligent control system automatically adjusts the rotation speed and downforce according to the soil hardness, preventing drill jamming and rod breakage.
- Large-diameter deep pile construction. The maximum drilling diameter can reach 1500mm, and the maximum drilling depth is 35 meters. It meets the needs of most large-diameter cast-in-place piles in building construction, bridges, and municipal engineering projects.
- 360° full rotation operation. The upper turntable supports 360° full rotation, and the drill mast can tilt ±5° left and right, 5° forward, and 90° backward. It flexibly adapts to various construction angles and space constraints.
- Rapid soil-throwing function. The power head features a unique high-speed soil-throwing design, with a soil-throwing speed of 65 RPM, increasing efficiency by 20% compared to ordinary models. This advantage is particularly significant in clay layers and wet soil conditions.
- Tracked travel + self-loading and unloading. The tracked chassis has a travel speed of 3.2 km/h and a maximum gradeability of 39%. The machine can be loaded and unloaded from a flatbed truck independently, requiring no additional lifting equipment.
- It features both dry and wet drilling modes. The appropriate mode can be selected based on geological conditions: dry drilling is suitable for clay and hard soil layers, while wet drilling (with mud slurry wall protection) is suitable for sand layers and strata below the groundwater level.
