On June 11, as a convoy carrying the SWDM600 rotary drilling rig slowly drove out of the south gate of Sunward Industrial City, this crawler-type rotary drilling rig set off for its destination, the Philippines, where it will be quickly deployed to the pile foundation construction task of the Philippines cross-sea bridge project, further expanding the "Belt and Road" circle of friends for China's high-end equipment manufacturing.

It is understood that the SWDM600 rotary drilling rig exported to the Philippines this time is a super equipment independently developed by Sunward for ultra-deep, ultra-large, and ultra-hard pile foundation drilling construction, with a maximum drilling diameter of 3.5 meters and a maximum drilling depth of 145 meters. It boasts a number of original innovative technologies in terms of ease of disassembly, assembly and transportation, drilling stability when penetrating rock, and intelligent operation.

1. Solving the long-distance transportation challenge

With ingenious mechanisms, the SWDM600 rotary drilling rig features a self-loading and self-unloading crawler chassis, allowing the massive upper and lower structures to be quickly separated and assembled. During machine transfer, no large crane is needed for assistance; the chassis telescopic outrigger mechanism enables convenient self-loading, reducing the time and cost of relocating super-large equipment while also solving the challenges of excessive width, weight, and height during transportation of super-large equipment.

2. Solving the stability and safety challenges during operation

Due to the variable environment and complex working conditions during construction, safety is always the bottom line in the construction process. The SWDM600 rotary drilling rig relies on its proprietary patented slewing brake device and control technology. The original stabilizing device connects the upper and lower structures into one, which not only effectively enhances drilling stability but also prevents damage to the slewing mechanism from severe vibration during drilling, effectively solving the problems of poor machine stability and low construction quality caused by large slewing impact during high-torque and complex formation construction. In terms of safety assurance, multi-directional cameras provide 360-degree full-view monitoring, combined with audible and visual alarms and emergency stop buttons, ensuring construction safety in all aspects.

3. Upgraded construction efficiency and diverse functions adaptable to various working environments

To increase construction efficiency and diversify functions, the SWDM600, based on the construction and management characteristics of super-large rotary drilling rigs, offers multiple drilling modes that can be selected according to different formations and pile diameters to improve construction efficiency. Its main winch has high lifting force and a long pressurization stroke, enabling one machine to serve multiple purposes such as installing large-diameter long casings. It is also equipped with a centralized lubrication system, making routine maintenance simple and convenient, saving time and effort.

Deepening the domestic market while expanding into international markets, at the delivery ceremony that day, Sunward Chairman He Qinghua pointed out in his speech that the export delivery of Sunward's largest rotary drilling rig SWDM600 is another fruitful result of Sunward's "pilot-style" innovation philosophy, demonstrating not only the "Sunward strength" in the global construction machinery industry but also the demeanor of a great nation.

In the future, Sunward will continue to actively respond to the national "Belt and Road" initiative, adhere to the pilot-style innovation philosophy, continue to make breakthroughs in core technologies and manufacturing processes, strive to create maximum value for customers, and continuously launch engineering equipment products with global influence.
