As core equipment in industrial production and engineering construction, the quality of cranes is directly related to construction safety, production efficiency and service life. Container Spreader is a core supporting component of container cranes, specially used for grabbing and hoisting containers, connecting cranes with containers. It is an indispensable equipment for container hoisting in terminals, warehousing and other scenarios, and its accuracy and durability directly affect hoisting efficiency and safety. Henan Mine has always taken "ingenuity and exquisite craftsmanship" as its core principle, regarded product quality as its lifeline, and strived for excellence in the R&D and manufacturing of Container Spreader. Combining the industry concept of Spreader Per Container, it customizes exclusive spreaders for different specifications of containers, and interprets the ingenuity and responsibility in the field of hoisting machinery and Container Spreader manufacturing through real project cases.
Ingenuity lies in every welding process, laying a solid foundation for products with precise control, which is fully reflected in the production of Container Spreader. Henan Mine has built a fully automatic double-beam main beam inner seam robot welding workstation. Through automatic positioning welding by robots and L-arm hydraulic flipping, it ensures that the welds of crane main beams and Container Spreader are uniform and firm, with accuracy reaching the top industry standard. For the 1000t gantry cranes and supporting Container Spreader manufactured for a terminal project of China Railway, the requirements for welding accuracy and connection accuracy are extremely high. By optimizing the flexible production line process, we shortened the production time by 40% while ensuring the accuracy meets the standards. The equipment was successfully applied to a large terminal in the upper and middle reaches of the Yangtze River, undertaking core hoisting tasks. In addition, the 80t overhead cranes and supporting Container Spreader customized for a large domestic iron and steel enterprise have optimized processes and anti-wear treatment for high-temperature and dusty environments, and have been operating stably for 3 years without any failures, winning high recognition.
Ingenuity lies in every core component, adhering to the bottom line of quality through strict material selection. Henan Mine insists on independent production of core components, strictly controls quality throughout the process, and practices the concept of Spreader Per Container to customize Container Spreader suitable for different specifications of containers. Crane wheels adopt intelligent forging technology and high-quality raw materials to improve durability; Container Spreader is made of high-strength wear-resistant steel, with optimized structural design, and has impact resistance, corrosion resistance and other characteristics. The 42t automatic container gantry cranes and supporting Container Spreader manufactured for a key project in Russia adopt low-temperature resistant materials and optimized sealing design for extremely cold environments, realizing stable operation at -40℃ and winning high praise from President Putin. The explosion-proof cranes and Container Spreader manufactured for a coal mine in Shanxi have undergone explosion-proof transformation, adapting to the flammable and explosive underground environment, effectively ensuring the safety of material hoisting and solving the industry's explosion-proof problem.
Ingenuity lies in every quality inspection, guarding product safety with a rigorous attitude. Henan Mine has a professional testing center equipped with precision testing equipment, and built a special testing platform for Container Spreader to conduct comprehensive testing on its load-bearing capacity, connection accuracy, etc., in line with the quality requirements of Spreader Per Container. For the automatic mold handling cranes and supporting Container Spreader customized for a well-known domestic automobile enterprise, the accuracy requirement reaches the millimeter level. We implement a "quality forward" model, conduct full-process supervision and inspection one by one to ensure stable transfer, which greatly improves the enterprise's production efficiency after delivery. The quayside container cranes and supporting Container Spreader customized for a port in Shenzhen have undergone more than 10 special inspections, operating stably under high frequency and high load, with a daily average operation volume of 800 TEUs, helping the port improve efficiency.
Ingenuity also lies in the persistence and innovation of employees. The average working life of core technical employees in Henan Mine exceeds 15 years. Through skill training and innovation incentives, it absorbs "golden ideas" from the front line, optimizes the welding and assembly processes of Container Spreader, and improves production efficiency and quality. The cranes and supporting Container Spreader provided for the intelligent warehousing workshop of Yancheng Port optimize intelligent scheduling and connection accuracy, reserve upgrade interfaces, practice the concept of Spreader Per Container, and help build a model of intelligent warehousing; the "Kuangyuan" brand cranes and Container Spreader exported to Malaysia integrate intelligent technology, customize specifications suitable for local containers, and contribute to the "Belt and Road" projects; the special cranes and supporting Container Spreader manufactured for the Inner Mongolia wind power base are suitable for wind power equipment containers, ensuring efficient installation and winning unanimous praise.
Over the years, Henan Mine has adhered to the concept of "ingenuity and exquisite craftsmanship for quality", implemented the standard of Spreader Per Container, and showed awe for quality in every link from welding, material selection, inspection to the improvement of employees' skills. Whether it is domestic projects or overseas projects, it delivers every crane and every set of Container Spreader with exquisite quality. In the future, Henan Mine will continue to focus on details, optimize technology, create safer and more efficient hoisting equipment and Container Spreader, base itself in China and go global, showing the ingenuity and strength of China's hoisting manufacturing.
