From August 15 to 17, the 2025 Mid-Year Meeting of the Pile Foundation Land Elite Association (Zhuanggong Luyinghui), themed "New Internationalization Driven by Quality and Innovation," was grandly held in Xiangtan, Hunan. The meeting brought together industry elites including general managers, marketing heads, industry consultants, and specially invited guests from member units.

     As an important agenda item of the meeting, on August 17, the delegates made a special trip to member enterprise Hunan Volga Pile Foundation Machinery Equipment Co., Ltd. (hereinafter referred to as "Volga") for an on-site visit, to gain an in-depth understanding of the development path of this industry benchmark enterprise. This was also an important consideration in choosing Xiangtan as the venue for this meeting.

     Entering Volga, the brand philosophy embodied in the six large characters "Excellence, Achievement, Future" was particularly eye-catching. Accompanied by General Manager Huang Jun and members of the leadership team, the delegates went deep into the production frontline and conducted an on-site inspection of the complete production process from raw material processing to finished product assembly, gaining a detailed understanding of the enterprise's breakthrough achievements in intelligent manufacturing, technological innovation, and other aspects.

     As a representative enterprise in the field of R&D, manufacturing, and remanufacturing of rotary drilling rig power heads, Volga has become a major supplier in the industry by virtue of strong technical strength and a solid market reputation. The company has more than 100 employees and is equipped with advanced equipment such as large laser cutting machines, CNC bending machines, and CNC machining centers. Based on universal and modular design, it has formed full-chain professional capabilities ranging from power head development and rapid customization to aftermarket services.

     With modular design as its core concept, Volga's product line covers the full TR60-TR550 series of power heads and accessories, providing supporting services for well-known enterprises such as Zoomlion and CRRC, and has been awarded the title of "Excellent Supplier." The company has established four major service centers in Wuhan, Guangzhou, and other locations to provide customers with comprehensive technical support.

     As the core equipment for pile foundation construction, the quality and reliability of the power head of a rotary drilling rig directly affect construction efficiency. At the R&D stage of the power head, Volga uses professional force analysis software to optimize the structural design, significantly extending the service life of key components. According to market feedback, some Volga power heads have been operating stably for more than 20,000 hours while still maintaining efficient working condition.

The key bars are forged from high-quality alloy steel and, after special heat treatment, possess both wear resistance and impact resistance;

The sliding plates use customized polymer materials, with a service life increased by 30% compared with ordinary products;

The gear system simulates actual working conditions through professional software, and the tooth root bending life can reach tens of thousands of hours.
