With summer breezes and sweltering heat, foundation engineering is in the golden period of intense construction. Recently, in Chongfu Town, Tongxiang City, Jiaxing, the Zoomlion ZR550G has won customer praise for its low fuel consumption, high stability, and high efficiency, and has become a core force in the construction of the Su-Tai Expressway Nanxun to Tongxiang section and the Tongxiang to Deqing connecting line (Phase II) project.

It is understood that in the drilling operations of this project, the Zoomlion ZR550G is more suitable for large-diameter 100-meter deep pile conditions, and is the best choice for high-difficulty projects such as extra-large bridges, highways, and building construction. The equipment adopts extreme torque dynamic matching technology, with greater and more stable output power, and fuel consumption is reduced by more than 10% compared to the whole machine. It is equipped with three slewing reducers for greater locking force. The chassis jacking cylinders and expansion cylinders can be optionally equipped with rational control functions, making it safe and reliable. At present, the ZR550G has completed 4 piles, and the 5th pile has been drilled to 82 meters, with a pile diameter of 2.8 meters and a pile depth of 115-131 meters. On average, one pile is completed in one and a half days, with fuel consumption of 37 liters/hour. The equipment uses a 2.8-meter drill bit for one-time hole formation, saving time and cost for customers to the greatest extent.

"The Zoomlion G series 550 class is adept at projects with high standards, great difficulty, and tight schedules. The main winch adopts a full-drilling-depth single-layer rope arrangement with large pulling force, the power head has large torque, high efficiency, stability, and fuel savings! Choose Zoomlion, and good luck will follow!" said the satisfied customer.

The Su-Tai Expressway is a major project to implement the national strategy of integrated development of the Yangtze River Delta region, promote the "Four Major" construction of Zhejiang Province, and support the integrated development of Jiaxing and Huzhou. It is of great significance for improving inter-provincial connectivity between Jiangsu and Zhejiang, providing transportation support for the World Internet Conference, and promoting economic development in the Yangtze River Delta region. This construction project is the Su-Tai Expressway Nanxun to Tongxiang section and the Tongxiang to Deqing connecting line (Phase II) project. The total length of the project is about 44 kilometers, including the main line of 24.5 kilometers (including 28 kilometers in Nanxun District) and the connecting line of 19.5 kilometers (including 16 kilometers in Deqing County). The construction period is 36 months, and it is the largest transportation construction project in Jiaxing's history in terms of investment.

Zhejiang Jifeng IoT Technology Co., Ltd., as an alliance customer of Shanghai Zoomlion Piling Machinery Co., Ltd., is a professional enterprise focusing on large lifting equipment leasing. It is at the leading level in the industry in subdivided fields such as medium and large tonnage crawler cranes and rotary drilling rigs, and owns 109 Zoomlion rotary drilling rigs. It is full of praise for the G series rotary drilling rigs and has purchased multiple ZR550G units.

The Zoomlion G series National IV rotary drilling rigs currently perform excellently in the market and are typical products for large pile construction in the foundation construction field. Their fuel-saving characteristics are deeply favored by customers. In addition, Zoomlion has fulfilled its commitment to nanny-style service for large models, adhering to the technological innovation concept of "technology is the root, products are the foundation," and creating value for customers.
