Thimble Hook Clevis is an indispensable key connection component in power transmission, communication cable installation and aerial work, and is designed for high-load scenarios. It adopts the classic structure of U-shaped shackle and eye bolt, which can be flexibly adapted to insulators, steel strands, optical cables and other equipment to achieve safe and reliable mechanical connection. Thimble Hook Clevis produced by Handan Jinmai Fastener Manufacturing Co., Ltd. is forged with high-strength alloy steel, and the surface is hot-dip galvanized or Dacromet anti-corrosion treated. It is suitable for extreme weather and complex working conditions, and is widely used in power transmission and transformation projects, communication base stations and railway contact network systems.
1. Ultra-high load-bearing capacity
Dynamic load reaches 10 tons, static load exceeds 15 tons, passed ISO 9001:2015 quality certification, complies with ASTM A489 standard, and meets the stringent safety requirements of high-voltage lines.
2. Patented anti-drop design
The U-shaped shackle is equipped with a double nut locking system and a pin self-locking structure to eliminate the risk of loosening due to vibration and ensure zero accidents in high-altitude operations.
3. 360° rotation and flexible adaptation
The rotatable hook design supports multi-angle force, is compatible with insulator strings, hardware and cable accessories of different specifications, and improves installation efficiency by 40%.
4. Military-grade anti-corrosion technology
The surface treatment can be hot-dip galvanized (average zinc layer ≥85μm) or environmentally friendly Dacromet coating, and the salt spray test is more than 1000 hours without rust, which is suitable for high-corrosion environments such as coastal areas and chemical plants.
Handan Jinmai adopts a full-process digital production system to ensure product consistency:
1. Precision die forging
A 10,000-ton hydraulic press performs closed die forging on alloy steel billets to eliminate internal pores and improve density and tensile strength (≥800MPa).
2. Intelligent heat treatment
Through computer-controlled temperature quenching (850℃±10℃) + tempering (450℃±10℃) process, the metallographic structure is optimized and the hardness is stabilized in the HRC 28-32 range.
3. CNC finishing
Five-axis linkage machine tools process threads and contact surfaces with an accuracy of ±0.02mm to ensure seamless engagement between shackles and bolts.
4. Triple quality inspection guarantee
Magnetic particle inspection (ASTM E1444) + ultrasonic inspection (EN 12680-3) + load destructive test, the defective rate is less than 0.1%.
