In the warm spring month of March, construction is in full swing! Zoomlion's G-series rotary drilling rigs have launched a delivery boom across the country. Recently, multiple Zoomlion ZR400G rotary drilling rigs headed to Mianyang, Sichuan, contributing to housing construction projects in the province.

At 2 a.m. on March 14, the equipment successfully arrived at the construction site. To ensure the customer's equipment was delivered on schedule, Zoomlion after-sales service personnel, after a brief communication with the customer, worked through the night by lamplight, building their original aspiration with craftsmanship and staying true to their service mission. From unloading and assembly to 100% delivery of the equipment's first pile, Zoomlion's after-sales service personnel followed the machine throughout the entire process, preparing emergency response measures for the customer and providing all-round protection for the equipment. The equipment assembly work was fully completed within 2 days, fulfilling with action the promise of 100% satisfaction in the first month of new machine delivery and always adhering to the service philosophy of "customer first."

"Ensuring service quality, guaranteeing the normal operation of equipment, satisfying customers, and being a service benchmark with attitude and warmth has always been my goal!" said an on-site service person. As a strategic cooperative customer, Mr. Han, General Manager of Zhongzhi Construction Co., Ltd., has always expressed high trust in Zoomlion's ultimate service and repeatedly praised the on-site service personnel, expressing his heartfelt gratitude.

It is understood that the geology of the pile foundation project of Phase II of Mianyang Jiuhuafu by China Construction Fifth Engineering Division is complex: the surface layer consists of medium-to-high-density cobbles and large-diameter boulders, the middle layer is high-strength hard rock, and after passing through the hard rock, multiple layers of mudstone-cobble interbeds appear, with the bearing stratum rock being even harder. Multiple rock cores must be extracted from each pile. After trial pile analysis, Mr. Han of Zhongzhi Construction Co., Ltd. ultimately proposed a construction plan using full casing follow-up combined with a cobble grab bucket and Zoomlion ZR400G rotary drilling rigs equipped with densely spaced core barrels for rock penetration. This not only ensured smooth hole formation but also improved hole-forming efficiency. Zoomlion's "Big G" efficiently penetrated rock, helping the project reduce the construction period and complete quickly.

With strong power, high stability, and a comfortable experience for customers, the Zoomlion ZR400G has won customer trust. According to the customer, "The Zoomlion ZR400G rotary drilling rig has low fuel consumption and high stability. It is powerful when drilling large piles, doubles efficiency, and can handle even hard rock with ease. Choosing it is definitely the right choice!"

Zoomlion will continue to use high-quality products and ultimate service to help Zoomlion foundation construction equipment shine brilliantly in the market, create value for customers, and add strength to the infrastructure industry.
