On July 26, Sunward's SWDM800H rotary drilling rig rolled off the production line smoothly, which not only further improved the company's rotary drilling rig product spectrum, but also marked the addition of another super "pile" equipment to the piling machinery industry.

This "pile" equipment was custom-developed for the special engineering environments, engineering strata, and engineering processes of pile foundation construction. It was born specifically for the Hangzhou Bay super project, can drill to a maximum depth of 155 meters, and can be used for ultra-deep large-diameter foundation construction in various super projects such as super high-rise buildings, long-span bridges, and high-speed railways and expressways.

"Last year we developed the super-large-tonnage rotary drilling rig SWDM1280, which has now been successfully applied to the construction of the Xihoumen road-rail dual-purpose bridge on the Ningbo-Zhoushan Railway, and on July 19, it took the lead in completing the first pile hole drilling for the 'world's largest' 6.3-meter-diameter, 106-meter-deep rotary drilled pile. Its successful development and application also provided experience we could draw on to complete the R&D of the SWDM800H in a relatively short period this time." According to Sunward R&D personnel, it took only 40 days from receiving the task to completing development, demonstrating Sunward's speed and innovative strength. Moreover, the SWDM800H rotary drilling rig incorporates the technical advantages of the SWDM1280, such as the industry's first high-inertia rotary platform braking force enhancement technology, modular design, and integrated intelligent operating system, and its performance is comparable to that of the SWDM1280.

In addition, the equipment is equipped with a high-power engine, large-displacement main pump, and four-motor power head, providing strong power, high torque, and fast speed. For deep-hole construction, an intelligent temperature-controlled "dual electronic fan" system is adopted to meet the high-power heat dissipation requirements of ultra-deep and ultra-large holes. The main winch uses a large-diameter drum to achieve single-layer rope spooling across the full drilling depth with a 6-section friction telescopic Kelly bar, providing super-large lifting capacity while extending the service life of the wire rope. For construction in high-salinity offshore environments, the luffing cylinder adopts a nickel-chromium composite plating process to improve the service life of the drilling rig.

Super projects drive the development of super equipment, and super equipment supports the realization of super projects. In the future, as a leading enterprise in piling machinery, Sunward will continue to uphold the concept of "pilot innovation," actively respond to national, market, and customer needs, develop more high-end, specialized, and complete sets of innovative products of various types, and lead the development of the industry.
