Digging to a depth of 1400 meters, with a total weight of only 8.5 tons! The LAND SONG L-12 drilling rig - why does it make field exploration so much easier?
The efficiency and safety of geological drilling are determined by the degree of compatibility between equipment performance and field conditions. Factors such as transportation to the site, adaptability to working conditions, equipment breakdowns, and accidents during the borehole drilling process are four common issues that have long hindered the progress of the project.

Exploring the "Land Song" L-12 Drilling Rig: Reconstructing the Boundaries of Field Drilling with Ingenious Design
In the vast mountainous and forested areas, drilling operations have never been an easy journey. Limited equipment access, insufficient environmental adaptation, reliance on experience in operation, and lack of safety redundancy - each aspect is a test of efficiency and resilience. And the "Land Song" L-12 drilling rig was specifically designed to solve these practical problems. It is not just a machine, but a systematic solution for field construction.
1. Entry is safe, transition is smooth.
The transportation of large equipment along the rugged mountain roads often marks the beginning of project delays. The L-12 complete machine weighs 8.5 tons and has an overall size of 4955×2245×2492mm. It is equipped with a crawler-type walking mechanism and can be transported by ordinary flatbed trucks, significantly reducing the requirements for the conditions of the entry roads. From one construction site to the next, the transfer is no longer a cumbersome project but a smooth and orderly standard process. The non-operation time is effectively compressed, and the turnover efficiency among multiple construction sites has been significantly improved.
2. Unafraid of severe droughts, suitable for both hot and cold climates
High temperatures and water shortages are the most challenging "examiners" for hydraulic systems. The L-12 adopts a wind-cooled hydraulic cooling solution, and throughout the process, it does not require external water source support. Whether in arid deserts, during hot summers, or even in cold winter environments, the system can maintain stable operation. By simplifying auxiliary equipment and reducing maintenance points, the equipment truly becomes a "24/7" working partner.
3. Intelligent speed control, precise drilling
The changes in the strata occur rapidly, and frequent manual adjustments of speed and torque not only require experience but also increase losses. The L-12 power head is equipped with an automatic speed control function, with a maximum torque of 4200 Nm and a maximum speed of 1300 rpm. It can match the output mode in real time according to the resistance of the strata. The operation is more simplified, the drilling is more accurate, and the lifespan of the drill pipe is effectively protected as a result.
4. Deep hole operations, with sufficient safety margin
During deep hole drilling, the lifting force serves as the safety line. The L-12 feed force reaches 79 kN, and the lifting force is 127 kN. The drilling angle can be freely adjusted within the range of 45 to 90 degrees. The feed speed can be controlled with stepless speed variation. The auxiliary hoist's lifting speed can reach up to 600 m/min, with ample power reserve. This provides necessary redundancy for hole safety in complex strata. Even in the face of emergencies, it can be handled calmly.
5. Circulatory System, Smooth and Reliable
The stability of the flushing fluid supply directly affects the slag discharge effect, the cooling of the drill bit and the safety of the hole wall. The L-12 model is equipped with a three-cylinder piston high-pressure mud pump, with a maximum flow rate of 180L/min and a maximum pressure of 8MPa. The output is stable and continuous, fully meeting the strict requirements of the circulating system for deep and medium-depth drilling, and providing continuous and reliable "blood" support during the drilling process.
6.Advanced anti-corrosion technology, ensuring efficient maintenance.
The humid and rainy outdoor environment is an accelerator for equipment aging. The L-12 complete machine adopts an electrostatic spraying + KTL powder spraying composite coating process, which has a much better anti-corrosion performance than traditional spray painting treatment. The modular design makes fault diagnosis and component replacement more direct and efficient, significantly reducing the downtime for maintenance. In addition, optional Icas remote intelligent management system and generator sets can be installed to achieve remote monitoring of equipment status and autonomous power supply in the field, further enhancing the convenience and independence of construction management.
The L-12 drilling rig is not only a systematic response to key aspects such as transportation, environment, operation, safety, and maintenance in field drilling, but also an evolution of engineering thinking. It comprehends the complexity of the field and respects the time and effort of the construction workers. For teams that are seeking efficient, reliable, and adaptable drilling equipment, the L-12 from Earth's Song is worthy of your in-depth understanding and attention.
