Far ahead—topping the hot search charts multiple times this September.

Far ahead—this proves the hard strength of China's technological innovation, expresses the Chinese people's admiration and pride for domestic products, and further strengthens their national confidence and pride.

Far ahead—this is a notable trend in the rise of domestic products. In the field of rotary drilling rig manufacturing, domestic brands have likewise taken the lead in launching the world's first motor-direct-drive pure electric rotary drilling rig.

"Far ahead"

From following the pack to overtaking on the curve

Being far ahead rests on leading technological strength. The more key technologies one masters, the stronger the capacity for independent innovation.

At the end of the 20th century, China's rotary drilling rigs mainly relied on imports. In the early 21st century, domestic OEMs began to develop and manufacture rotary drilling rigs, but their overall control architecture was not fundamentally different from that of imported equipment. It was not until 2020 that a domestic brand—Yutong Heavy Industries—took the lead in launching the world's first independently developed motor-direct-drive pure electric rotary drilling rig, changing the power source of the rotary drilling rig from an engine to batteries, replacing the complex hydraulic system with simple wiring harnesses, and replacing hydraulic control with more sensitive and precise electronic control. The motor directly drives the reducer, which in turn drives the winch and the power head to work, reshaping the rotary drilling rig with electric technology.

Yutong Heavy Industries took the lead in launching the world's first motor-direct-drive pure electric rotary drilling rig, drawing on the strong new energy R&D strength of the Yutong Group. Yutong has nearly 30 years of accumulated new energy experience, cumulative sales of more than 180,000 new energy vehicles, independent and controllable core "three electrics" technologies for new energy, and its project "R&D and Industrialization of Key Technologies for Energy-Saving and New Energy Buses" won the second prize of the National Science and Technology Progress Award. In addition, Yutong has one world-class engineering technology center, 7 national-level and 27 provincial-level scientific research and innovation platforms, has formulated and revised 280 national and industry standards, and has been granted 4,316 patents in total, ranking first in the industry in both the number of new energy patent applications and the number granted.

As soon as the Yutong electric rotary drilling rig was launched, it was well received by the market and attracted many international friends who came to exchange and learn. At this point, the domestic electric rotary drilling rig achieved a breakthrough from 0 to 1, and also completed the transformation from following the pack to overtaking on the curve.

"Far ahead"

Technological advantages are even more pronounced

Being far ahead rests on continuously upgrading technological levels. Yutong Heavy Industries keeps accelerating forward, writing a new chapter in the development of electric rotary drilling rigs through iterative upgrades of its technology platform.

Recently, with the support of Yutong's Ruikong E platform, Yutong Heavy Industries launched its latest core three-electric system assembly for electric rotary drilling rigs—the "D-Power Ultra-Integrated Electric Chain," which comprehensively upgrades multi-motor control technology: motor torque sensitivity is increased 4 times, instantaneous burst is raised by 80%, and the electric rotary drilling rig penetrates rock more easily; the newly upgraded early warning system monitors more than 100 components in real time, with an early warning accuracy rate of ≥90%, making whole-machine construction more stable; since the first electric rotary drilling rig was launched in 2020, cumulative working hours have exceeded 70,000 hours, the operating range covers more than 20 provinces and cities, and it adapts to more than 90% of construction conditions nationwide, giving the machine stronger adaptability to working conditions; the range-extender system is fully coupled with the operating system, and the reinforced energy recovery system saves more than 80% in pure electric mode and more than 50% in range-extender mode, making construction more economical!

The D-Power Ultra-Integrated Electric Chain makes the technological advantages of Yutong electric rotary drilling rigs even more pronounced, creating greater value for customers while continuously driving the industry forward!

Ask not how far the road ahead may be; just press on through wind and rain!For China's independent technological innovation, many people are gazing at the stars and bearing the weight as they move forward. The stars do not fail those who travel by night, and "far ahead" products will bring more inspiration to these stargazers.
