Zoomlion new road roller ZRS322E off the assembly line

"Zoomlion hopes that the new roller ZRS322E will become a landmark product that will lead the development of the industry and promote the industry's 'all-wheel drive' upgrade revolution!"

On February 22, on the first day of the start of the Spring Festival, Zoomlion Road Machinery's new 4.0 new single-wheel dual-wheel drive roller ZRS322E was rolled out at Changsha Silicon Valley Industrial Park. This product is another masterpiece of the company's “Product 4.0” project. At the same time, it breaks through the cost problems of the industry's dual-drive products and will lead the industry in innovation and development and help customers create more value.

On the scene of a simple and solemn off-line ceremony, Li Qing, general manager of Zoomlion Road Machinery Division, delivered a speech and introduced the product development process and product advantages. The company’s vice president Xiong Yanming and Guo Xuehong attended the meeting.

According to reports, Zoomlion's predecessor, the Changsha Construction Machinery Institute, was once one of the birthplaces of China's road machinery design and R&D. The Road Machinery Division adheres to the technological accumulation and continues to improve its scientific and technological content in the application of a large number of practical foundations. It has now fully grasped the full hydraulic dual drive technology and is focused on the R&D and production of dual drive roller products.

What is the difference between a dual drive roller and a single drive roller?

The results of compaction tests conducted by an authoritative university show that the compaction capacity of the 20-ton dual-drive roller is equivalent to 26 tons of single-wheel roller, and the full-hydraulic dual-drive without driven wheels will not cause soiling. Therefore, whether it is from the pressure capacity or uniformity of compaction, the operating performance of the twin-wheel roller at the same tonnage level is much better than the single-wheel roller.

Not only that, Zoomlion's dual drive roller has undergone a full range of technological innovations. Its full hydraulic dual drive roller work quality is 1.3 times that of single drive, unit excitation force is more than 10% higher than peer dual drive, and can work normally under various harsh climates such as -20°C~58°C.

Although the industry generally knows that dual-drive is better than single-drive, it is deterred by its high price, and when it comes to actual purchases, single-wheel rollers with lower prices tend to be used only for sites with high road quality requirements.

As a product with four years of R&D, which is both cost-effective and technically powerful, Zoomlion expects the ZRS322E roller to change this situation and promote the industry's “full-duty dual-drive”.

A technical person in charge of Zoomlion explained: “The so-called 'full-duplex drive' aims to optimize the manufacturing cost through the technical innovation, process optimization and lean manufacturing of our roller product R&D team to ensure that the production cost is reduced. The production of higher-quality dual-drive rollers significantly reduces the threshold for the purchase of dual-drive rollers, enabling more customers and even the entire crew to experience the appeal of dual-drive pressure-reduction devices that are 'useful, efficient, and energy-efficient.'
