At 10:18 a.m. on September 25, the Yutong YTR416HE electric rotary drilling rig equipped with the D-Power ultra-integrated electric chain officially rolled off the production line. The successful application of the D-Power ultra-integrated electric chain marks another major breakthrough for Yutong Heavy Industries in the electric rotary drilling rig sector.

Rock penetration, stability, and energy savings are the key concerns of many electric rotary drilling rig owners, and the D-Power ultra-integrated electric chain was developed precisely against this backdrop. Leveraging the technical advantages of the Group's Ruikong E platform and the accumulated data from electric rotary drilling rigs across multiple working conditions and scenarios, Yutong Heavy Industries has launched this core three-electric system assembly for electric rotary drilling rigs, delivering users a high-quality product that is "stronger in rock penetration, more stable in construction, highly adaptable, and more energy-efficient."

1. Stronger rock penetration: The Yutong D-Power ultra-integrated electric chain features comprehensively upgraded multi-motor control technology, with motor torque sensitivity increased 4 times and instantaneous burst power raised by 80%, making rock penetration easier.

2. More stable construction: The Yutong D-Power ultra-integrated electric chain features a newly upgraded early-warning system that monitors more than 100 components in real time, with an early-warning accuracy of ≥90%, making whole-machine construction more stable.

3. Strong adaptability: Yutong electric rotary drilling rigs have accumulated more than 70,000 hours of working time, with operations covering more than 20 provinces and cities and adapting to over 90% of construction conditions nationwide, giving the machines stronger adaptability to working conditions.

4. Greater energy savings: With the Yutong D-Power ultra-integrated electric chain, the range-extender system is fully coupled with the working 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!‍

Technological advancement continues to lead, and the all-new system commands the peak. With the support of the D-Power ultra-integrated electric chain, Yutong electric rotary drilling rigs achieve a comprehensive leap in value, creating greater value for customers.
