Recently, at the construction site of the Qihe-Jinan section expansion project of the Beijing-Taipei Expressway, a key project in Shandong Province, two ZR400G rotary drilling rigs are contributing powerful momentum to infrastructure development across the Qilu region. Since the second half of 2022, Zoomlion's G-series rotary drilling rigs have been delivered at an accelerating pace across the country, quickly taking on the role of main construction force—heralding the rapid arrival of an outstanding "Great G New Era."

"The ZR400G rotary drilling rig is a derivative model of the ZR420G-II, which won the '2022 China Piling Machinery Market Annual Product Award,' and market response has consistently been very positive. This project involves soil geology, with a pile diameter of 2 meters and a pile depth of 60 meters. The ZR400G began entering the site in early December last year; it offers strong power and high stability, and can drill one pile in an average of 7 hours, earning high customer recognition," introduced Peng Wu, a service engineer at Zoomlion's Shandong Branch.

In recent years, Zoomlion's Foundation Construction Company has strived to climb new heights in technological innovation, R&D and manufacturing, and market scale, and in 2022 launched the all-new G-series rotary drilling rigs. The G-series products feature a brand-new appearance and comprehensively upgraded performance configurations; the entire product line has undergone more than a year and thousands of hours of verification, and is characterized by stable, efficient, robust and solid performance, winning broad market recognition.

At present, the G-series rotary drilling rigs already have a relatively complete product spectrum, including the small models ZR180G and ZR240G suited to soil layers, the ZR360G versatile for building and bridge piles, and the large rotary drilling rigs ZR420G-II, ZR420GP, and ZR550G with strong large-pile construction capability. G-series rotary drilling rigs are being delivered to customers across various regions, fully demonstrating their outstanding advantages in all types of projects.

In the northwest region, small rotary drilling rigs represented by the ZR180G are being continuously delivered, suitable for foundation construction of wind power generators. In Hunan, Guangdong, Shandong, Chongqing and other places, large rotary drilling rigs such as the ZR400G, ZR420G, and ZR420GP are frequently entering sites, supporting the construction of river-crossing bridges, secant pile walls for underground projects, and building projects in hard-rock areas with their strong rock-penetration capability and large-pile construction capacity with a maximum hole diameter of 2,800 mm.

Relying on years of technological accumulation and excellent product quality, Zoomlion's foundation construction machinery is striving to build its flagship G-series rotary drilling rig family, setting off a market wave and working hand in hand with customers for win-win success in the Great G New Era with superior equipment and overall construction solutions.
