In May 2025, the 4th Changsha International Construction Machinery Exhibition was grandly opened. As an important participant in the construction machinery field, Jiuman Machinery brought its core product, Kelly Bar, to this industry event, shining brightly at the exhibition and celebrating this grand event with colleagues in the global construction machinery industry.
Walking into the booth of Jiuman Machinery, Kelly Bar immediately caught the attention of visitors with its unique design and exquisite craftsmanship. Kelly Bar is a key component used in rotary drilling rigs and plays a vital role in foundation engineering construction. It can effectively transmit the torque and pressure of the drilling rig to the drill bit, thereby realizing drilling operations under different geological conditions.
Jiuman Machinery’s Kelly Bar is ingeniously designed. In order to adapt to the complex and changeable geological environment, it uses high-strength steel and undergoes special heat treatment process, which greatly improves the wear resistance and fatigue resistance of the drill pipe. The careful selection of this material ensures that Kelly Bar can still maintain stable performance under long-term and high-load working conditions, reducing construction interruptions caused by drill pipe damage and providing a strong guarantee for the efficient advancement of engineering construction.
In terms of structure, Jiuman Machinery’s Kelly Bar has been optimized. The connection between multiple drill pipes adopts high-precision processing technology and fits closely, which can not only effectively prevent shaking and deviation during drilling, but also ensure the efficient transmission of torque and pressure. This stable structural design enables the verticality and hole diameter accuracy of the drilled hole to be well controlled, meeting the increasingly strict requirements of modern foundation engineering for construction quality.
At the exhibition site, the technicians of Jiuman Machinery enthusiastically explained to every customer who came to consult. They introduced in detail the working principle, performance characteristics and applicable construction scenarios of Kelly Bar. From the foundation construction of urban high-rise buildings to the construction of large-scale infrastructure such as bridges and ports, Kelly Bar can rely on its excellent performance to provide reliable drilling solutions for engineering.
Construction machinery practitioners from all over the world, including equipment manufacturers and representatives of construction enterprises, have stopped to communicate at the booth of Jiuman Machinery one after another. Many foreign customers have shown strong interest in Kelly Bar. They asked in detail about the technical parameters, service life and after-sales service of the product. The staff of Jiuman Machinery answered one by one with a professional and patient attitude. Through on-site product display and technical explanation, foreign customers fully understood the advantages of Kelly Bar, and many customers expressed their intention of further cooperation on the spot, hoping to introduce Jiuman Machinery’s Kelly Bar into the construction machinery market of their own countries.
In addition to product display and customer communication, Jiuman Machinery also actively participated in various professional activities during the exhibition. In activities such as the “2025 New Construction Machinery Product and Technology Release and Global Procurement Business Exchange – Special Session for Small and Medium-sized Enterprises Trading with Africa”, representatives of Jiuman Machinery had in-depth exchanges with enterprise representatives from Africa and other regions, shared the application cases and successful experiences of Kelly Bar in the international market, and also understood the needs and development trends of construction machinery markets in different regions, laying a foundation for Kelly Bar to further expand the international market.
This Changsha International Construction Machinery Exhibition is an excellent opportunity for Jiuman Machinery to show its strength and expand the market. By competing and cooperating with elites in the global construction machinery industry on the same stage, Jiuman Machinery not only let more people recognize the excellent performance of its Kelly Bar, but also further clarified the future development direction. Today, as the construction machinery industry continues to develop and progress, Jiuman Machinery will continue to uphold the spirit of innovation, continue to research, develop and improve products such as Kelly Bar, provide more high-quality and efficient construction machinery products for global foundation engineering construction, and contribute its own strength to the development of the industry.
