Why does the Zoomlion ZR280C-3 rotary drilling continue to be hot? 6 highlights

Rotary drilling has become an essential basic construction equipment in various infrastructure fields such as railways, highways, bridges, tunnels, port terminals, and construction sites. For a long time, Zoomlion's rotary drilling has been widely favored by customers with its strong and powerful advantages. The new generation of 4.0 “—3” series of intelligent products has received rave reviews. Among them, ZR280C-3 rotary drilling is among the domestic 280 series products, and its sales volume is in the forefront for a long time. It can be called the “golden brand product” in rotary drilling.

Zhang Fanghong, Product Manager of Zoomlion Foundation Construction Machinery Co., Ltd. introduced: “ZR280C—3 Rotary Drilling is a series of piles of R&D and manufacturing experience of Zhonglian Heavy Industry Co., Ltd. and a combination of international advanced technology. ZR280C—3 fusion At the same time, the product advantages have been further improved.” Subsequently, Zhang Fanghong summarized the product features with six “more” words: stronger, smarter, more reliable, more stable, more convenient and more efficient.

According to reports, ZR280C-3 has strong power and strong rock-inputting capability, and can be applied to various geological constructions such as mud layers, soil layers, sand layers, and strong weathering, moderately weathered, weakly weathered rock layers, etc. Among the various aperture projects such as piles, bridge piles and deep foundation pit support. In addition, the product has a low-speed and high-torque function of the power head, which can match various working conditions; its main hoisting maximum lifting force is up to 340KN, with 36mm wire rope; optional 17m drill pipe, the maximum drilling depth is 94m; The earth has improved product construction capabilities.

“In today's continuous improvement of intelligent technology, more and more construction project construction enterprises have higher expectations for the intelligentization of construction machinery and equipment.” Zhang Fanghong introduced, “ZR280C-3 intelligentization is reflected in product operation and management. Aspects: First, the product is equipped with automatic functions, with one-button sweeping, bauxite, car display and other functions, the operation has been simplified; second, the product has intelligent interconnection function, 22 safety data, working status and 5 construction information realized Intelligent statistics, customers only need to easily manage the equipment through the mobile APP - Zhonglian e-housekeeper. In addition, intelligent applications also improve the security of the operation."

Through the unique design and application, Zoomlion Foundation Construction Machinery's R&D team has effectively improved the life of key components of the ZR280C-3 and made the products more reliable. For example, the product uses a single-layer reel and a double-cylinder configuration, which effectively extends the life of the wire rope and reducer. With the fourth-generation crawler walking system and the new impact-resistant rail clamp, the life of the travel system has been greatly improved. .

In order to improve the stability of the products, the R&D team of Zoomlion Foundation Construction Machinery Co., Ltd. has developed a double-triangular structure technology. The luffing mechanism is an important working device for rotary drilling rigs. The parallel quadrilateral small triangle structure and the large triangular structure are used in the market, each with its own advantages and disadvantages. For example, the parallelogram small triangle structure has a large range of variation, and the mast can be lowered and folded, which reduces the transportation height and length. The disadvantage is that the front weight is heavy, the stability is slightly poor, and the torque cannot be withstood; the large triangular structure is characterized by the structure. Simple, stable, and able to withstand high torque. The disadvantage is that it must be disassembled during transportation, which is time-consuming and labor-intensive. The Zooming Mechanism of Zoomlion ZR280C-3 adopts the first double-triangular structure, which combines the stability of work and the convenience of transportation, and achieves the effect of “fish and bear's paw”. In addition, the ZR280C-3 has been further improved by the optimization measures such as lower center of gravity, shorter radius of gyration, and increased rigidity of the walking structure.

"ZR280C-3 transport and transfer is flexible and can be transported by whole machine or disassembled. The whole machine is equipped with professional jacking legs when it is assembled and disassembled, which can save a lot of transfer expenses," Zhang Fanghong said.

After the launch of ZR280C-3, it has been favored by customers. In addition to extensive participation in major domestic engineering projects, the products are also exported to Southeast Asia, the “Belt and Road” countries and regions and other overseas markets, and are highly praised by customers for their strong performance and high efficiency.

"ZR280C-3 is welcomed by the market and is the trust of customers. As a research and development personnel of the pile machinery, we will always take the customer's needs as the core, adhering to the research and development concept of 'technology is the root, the product is this', and forge ahead, Be brave in innovation, develop products with superior quality and strong performance, create greater value for customers and make greater contributions to the development of the industry,” Zhang Fanghong said.
