Dear Distinguished Visitors and Friends,

Welcome to the official website of Luoyang Jiujiu Technology Co., Ltd. (Jiujiu Tech)! Whether you are seeking a reliable partner for rock breaking equipment in major infrastructure projects or exploring innovations in rock breaking technology, we are truly honored by your visit.

Amidst the vigorous wave of global infrastructure development, the efficient advancement of tunnels, rail transit, water conservancy hubs, and other major projects relies heavily on high-quality rock breaking equipment. Having specialized in this field for nearly three decades, Jiujiu Tech, as a National High-Tech Enterprise, has always been rooted in technology, committed to quality, and dedicated to service. With profound industry expertise and mature international cooperation experience, we have provided reliable rock breaking solutions for numerous significant projects worldwide. Here, we sincerely present the four core reasons to choose Jiujiu Tech, hoping to build deeper trust and collaboration with you.

1. National-Level Technical Endorsement for Assured Quality

Our technical strength stems from long-term, in-depth participation in national key scientific research initiatives—from the National "Seventh Five-Year Plan" R&D on wear-resistant materials and TBM/Shield Machine National Science & Technology Projects to key programs like the "863 Program". We have also undertaken the SME Innovation Fund project for shield machine cutters and the National Torch Program project, and participated in formulating several national industry standards such as "Rock-breaking rolling cutter" and "Building construction machinery and equipment-Direct/reverse circulation drilling rig". Relying on the Henan Provincial Shield Machine Cutter Engineering Technology Center, our professional R&D team holds 85 intellectual property rights. Our core patents significantly enhance cutter wear resistance and service life, successfully solving complex geological construction challenges. Furthermore, the company holds international authoritative certifications like GB/T19001-2016/ISO9001:2015, ensuring our product quality fully complies with mainstream global engineering standards.

2. Comprehensive Product Portfolio for Precise Matching to Diverse Needs

We have built a complete range of rock breaking equipment systems, covering core products like Shield Machine/TBM Cutters, Engineering Drill Roller Cutters, Raise Boring Machines, and wear-resistant/heat-resistant components. Our 12-19 inch roller cutters are fully compatible with international mainstream tunnel boring machines (e.g., Herrenknecht) for seamless interchangeability without requiring modifications. For specific challenging conditions like large-particle cobble layers or hard rock formations, we offer end-to-end customized services from solution design and product development to manufacturing, helping enhance construction efficiency and reduce overall costs. With sufficient production capacity, we can annually manufacture 30,000 sets of rock breaking tools and 10,000 tons of wear-resistant/heat-resistant parts, ensuring stable bulk supply for various projects.

3. Mature International Service, Providing Global Support

Over the years, our products have been exported to numerous countries and regions across Europe, America, Southeast Asia, etc., successfully serving many major overseas infrastructure projects and earning widespread recognition from international clients. To better serve global visitors, we have established a professional international business team proficient in cross-border trade rules and multilingual communication, offering full-chain services including pre-sales technical consultation, in-sales installation guidance, and after-sales maintenance. Concurrently, we have optimized our global logistics and warehouse layout to effectively shorten delivery cycles, ensuring timely product arrival at project sites, and can flexibly adapt to different national technical standards, providing comprehensive support for project smooth progression.

4. Solid Operational Strength for Win-Win Long-Term Development

As an NEEQ-listed enterprise, we maintain standardized corporate governance structure and steady operational performance. In 2024, the company achieved an operating income of RMB 124 million with steadily growing net profit, demonstrating strong market competitiveness and development resilience. We consistently adhere to the philosophy of "Customer First, Quality Foremost, Integrity-Based, and Collaborative Synergy". We not only strictly control product quality but also strive to build long-term, stable, and mutually beneficial relationships with our partners. Moving forward, we will continue to deepen technological innovation, optimize our global service network, and contribute to high-quality global infrastructure development with superior products and services.
