Recently, the Yuchai YCR280 rotary drilling rig participated in the foundation engineering construction of the new campus of Xishui County No. 12 Middle School in Zunyi City, Guizhou Province. The equipment operated with high efficiency and low fuel consumption, earning high praise from the customer.

The all-new Yuchai YCR280 rotary drilling rig is equipped with a Cummins China IV X12 engine, enabling real-time power distribution. It also adopts a full set of imported hydraulic systems, offering high work efficiency, low fuel consumption, and strong power. It can quickly and accurately complete pile foundation construction with high economic benefits. The equipment also features a three-input power head, delivering greater output torque and stronger rock drilling capability, while the all-new rotary reducer with high braking torque makes construction more stable. An optional six-section friction-type drill pipe allows drilling depths of up to 80 meters.

The new campus of Xishui County No. 12 Middle School is located in Shanwang Subdistrict, Xishui County, Zunyi City, Guizhou Province, covering an area of approximately 52,969.9 square meters, with a project investment of about 160 million yuan. Alongside economic development, education must also keep pace, and the construction of the new campus of Xishui No. 12 Middle School is the most important step in improving supporting educational infrastructure. At this construction site, the strata for the Yuchai YCR280 rotary drilling rig are mainly strongly weathered phyllite, with a construction pile diameter of 1.2 meters, a maximum hole depth of 50 meters, and a hole-forming time of about 4 hours. During the special service period, the Yuchai service team closely monitored the equipment's construction conditions throughout, provided the optimal construction method, and assisted the customer with equipment maintenance to keep the equipment operating in optimal condition. The excellent performance of the Yuchai YCR280 rotary drilling rig in terms of high efficiency and fuel savings has been highly recognized by the customer, who plans to give priority to Yuchai rotary drilling rigs when adding equipment in the future.
