With an average of 25 days of construction per month and 15 hours of work per day, in just a year and a half, a single Yutong electric rotary drilling rig has accumulated 7,000 hours of operating time. This is not merely an accumulation of numbers; it highlights the efficiency and stability of the electric rotary drilling rig and underscores its outstanding performance in reliability and durability.

As key foundation construction equipment, the performance and efficiency of rotary drilling rigs directly affect project progress and quality. The Yutong 206AE pure electric rotary drilling rig purchased by Shandong Hi-Speed at the end of 2022 surpassed the 7,000-hour mark in just a year and a half. Such intensity is a severe challenge for any mechanical equipment. Why can the Yutong electric rotary drilling rig create the efficient legend of 7,000 hours?

Core Three Electrics · Independently Mastered

As a new energy vehicle model, the absolute stability of the core three electrics is the key to the reliability and efficiency of the Yutong electric rotary drilling rig. Yutong has nearly 30 years of accumulated experience in electric technology, cumulative sales of more than 200,000 new energy vehicles, and its new energy Ruikong technology and key power battery technologies have won the National Science and Technology Progress Award twice. Its mastery of core new energy "three electrics" technology empowers the high-quality development of electric construction machinery. Relying on its inherited high-quality genes and the Group's Ruikong E platform, the Yutong electric rotary drilling rig has built the exclusive D-Power ultra-integrated electric chain for electric rotary drilling rigs, featuring stronger rock drilling, more stable construction, and strong adaptability, ensuring that the electric rotary drilling rig is stable, durable, safe, and reliable.

Precision Manufacturing · Cornerstone of Quality

During the manufacturing process, Yutong electric rotary drilling rigs strictly follow high-standard and stringent production processes. Every component and every system is carefully selected and rigorously tested to ensure that it can still maintain good working conditions under extreme operating conditions. Yutong Group has also invested 1 billion yuan to build a world-class engineering technology center, covering professional laboratories for motors and electronic controls, power batteries, electromagnetic compatibility, and more, conducting all-round and systematic extreme verification of the core three electrics system internally, effectively improving reliability and durability.

Motor Direct Drive · Reliability Upgrade

The Yutong electric rotary drilling rig adopts motor direct drive, which not only simplifies the mechanical structure but also achieves smooth and efficient power output through precise electronic control technology, fundamentally reducing the incidence of mechanical failures and laying a solid foundation for the long-term stable operation of the equipment. In addition, equipped with the D-power ultra-integrated electric chain and a newly upgraded early warning system, it monitors more than 100 components in real time, with an early warning accuracy rate of ≥90%, providing operators with timely and accurate maintenance information, helping users formulate more scientific and reasonable usage plans, and further improving equipment reliability.

In the future, Yutong Heavy Equipment will base itself on industry needs, continue to leverage its technological advantages, lead the industry with more comprehensive advantages, and promote the green and high-quality development of the industry!
