Welcome to Handan Jinmai Power Line Accessories Manufacturing Co., Ltd.
The U-7 shackle is a fundamental and crucial connecting piece. As shown in the figure, it serves as a crucial component of the connecting piece. It connects other pieces of hardware together via a locking shackle, and bolts from above connect to yet another piece of hardware. The U-7 designation represents its rated working load of 7 tons (70 kN).
Product Key Features
*Handan Jinmai's U-7 is a national standard design (we also offer special heightened and lengthened designs suitable for different countries and regions). Produced in strict compliance with national (e.g., GB/T) and industry (e.g., DL/T) standards, its dimensions are standardized, allowing it to seamlessly work with similar wire ropes, chains, slings, and other rigging, offering excellent interchangeability and versatility. Available by model, with inventory available, we can deliver large quantities quickly within a week, providing convenient customer service.
*Handan Jinmai's U-7 is made of Q235B carbon steel with a hot-dip galvanized surface for corrosion resistance, durability, and cost-effectiveness. It weighs approximately 0.8 kg.
*Advanced manufacturing technology, primarily utilizing die forging. High-temperature heating and high-pressure die forming create continuous and complete metal flow lines, refine the grain size, and eliminate internal defects, significantly improving the product's overall mechanical properties, especially fatigue strength.
After forging, the shackle undergoes rigorous quenching and tempering (quenching and high-temperature tempering).
This process imparts high strength to the shackle body while maintaining excellent ductility and toughness, preventing brittle fracture during use.
The U-7 shackle, with its durability, safety, reliability, and versatile flexibility, has become a trusted connection solution for power plant operations. Choosing Handan Jinmai's U-7 shackle helps ensure safety and efficiency in power plant construction.
