In the field of foundation construction, Zoomlion Foundation Construction has steadily advanced its technological prowess, with the strategic vision of becoming a global provider of integrated solutions. Its extensive portfolio, comprising rotary drilling rigs and specialized diaphragm wall equipment, enables the company to satisfy over 80% of all foundation engineering requirements.
To effectively cater to diverse global construction scenarios—particularly high-stakes projects characterized by large-diameter deep piles, operations in complex geological strata, and foundations in karst terrain—Zoomlion has engineered a specialized series of full casing drilling rigs. This product line is comprised of the ZM series of oscillating casing drilling rigs (casing rotators) and the ZRT series of full rotary drilling rigs. Designed for international deployment, these products comply with various national and regional emission standards, including China III, China IV, and Euro V, thereby providing global clients with versatile and compliant solutions for their foundation construction needs.
Zoomlion's 4-meter diameter full casing drilling rig, recognized as the world's largest, played a pivotal role in the Suzhou Xitang River Drinking Water Project. It was the principal equipment for constructing a 100-meter deep, high-pressure algae elimination well. Operating in synergy with other customized Zoomlion machinery, the rig made a significant contribution to local environmental protection. Building on this success, and in deepened partnership with Kunming Jiecheng, Zoomlion Foundation Construction has subsequently upgraded the rig to comply with China IV emission standards. The refurbished equipment has now been deployed to a municipal engineering project in Hangzhou. This initiative not only builds upon valuable project experience but also powerfully demonstrates Zoomlion's commitment to market responsiveness and continuous product enhancement.

Zoomlion's ZM300G demonstrated exceptional capability during its inaugural project in Hong Kong. Tasked with a formidable casing extraction in Yuen Long, the operation involved a 3-meter diameter casing driven 51 meters to the rock surface, followed by RCD drilling to a total depth of 60 meters. A significant complication arose from the casing remaining in the borehole for 45 days, resulting in immense confining pressure from the surrounding soil and substantially increasing the operational difficulty. Nevertheless, the ZM300G flawlessly executed the extraction, leveraging its superior power and precision. This successful outcome garnered significant praise from the client and served as a testament to the equipment's reliability under extreme conditions.

The ZM300G oscillating casing drilling rig is a specialized piling rig developed by Zoomlion for the Hong Kong, Macau, and Taiwan markets, featuring the following characteristics:
1. The entire machine's structural components are designed with high-strength steel for stability and reliability.
2. Equipped with a Cummins X15 engine and Kawasaki hydraulic pumps for robust power.
3. Features innovative, controllable hydraulic flow-merging technology for fast response and high efficiency.
4. Utilizes a wireless remote control, enabling 360-degree operation within a 50m radius for safe and convenient handling.
5. An integrated high-power heat dissipation system ensures the system does not overheat during continuous, high-load operation in hot weather.
6. Delivers leading performance with a maximum rotary torque of 13,500 kN.m and a maximum extraction force of 8,450 kN.
Furthermore, other casing rotator models, such as the ZM200HH, have demonstrated high efficiency and stability in various complex construction environments, showing strong market prospects and a favorable return on investment in the Hong Kong, Macau, and Taiwan regions.

At Bauma CHINA 2024 in Shanghai, Zoomlion unveiled the ZM150L full casing drilling rig (casing rotator). This model can be directly connected to the power unit of a rotary drilling rig for combined operations and has already been successfully deployed in multiple projects across Europe.
It is now steadily gaining recognition and acceptance from customers in other parts of the world. Looking ahead, Zoomlion will continue to champion innovation, constantly improving product performance and service quality. The company is committed to providing superior full casing drilling rigs and solutions to the global foundation construction industry, further strengthening its international market presence and propelling the sector to new heights.
