In the wave of green transformation and efficient development, every number records a story of innovation and breakthrough. Shandong Expressway and Yutong Heavy Equipment are working together to write a brilliant chapter in the history of electric rotary drilling rigs. As of July this year, Yutong's electric rotary drilling rig has accumulated over 7,000 hours of construction in the past year and a half, and in the most recent 48-day period alone, it logged an additional 1,000 operating hours.
Milestone Achievement
In the past 48 days, the Yutong electric rotary drilling rig operated at an astonishing pace, accumulating 1,000 hours of work at an average of 21 hours per day. With this latest addition, the single unit has now exceeded 8,000 total hours of construction time, becoming the electric rotary drilling rig with the longest cumulative construction hours in China. This remarkable milestone is a testament to both the durability of the equipment and the demanding nature of the infrastructure projects it supports.
Operational Performance
At the Shandong Expressway construction site, the Yutong electric rotary drilling rig has won high praise from the project team for its outstanding performance. Whether facing complex and ever-changing geological conditions or high-intensity continuous operation schedules, Yutong electric rotary drilling rigs maintain stable operating conditions, ensuring both construction efficiency and quality. The ability to operate 21 hours per day with minimal downtime demonstrates the exceptional reliability and robustness of Yutong's electric platform under real-world working conditions. The 8,000-hour figure stands as the best proof of the stable and reliable performance of Yutong's electric rotary drilling rig technology.
Industry Benchmark
This construction case undoubtedly sets a new benchmark for the widespread application of electric rotary drills in the domestic market. By demonstrating that electric construction equipment can match or exceed the operational endurance of traditional diesel-powered rigs in real infrastructure projects, Yutong is paving the way for broader adoption of green construction technology across the industry. The partnership with Shandong Expressway serves as a powerful reference case for other major infrastructure developers considering the transition to electric construction machinery.
