Advanced Manufacturing & Quality Control

Weihua employs state-of-the-art CNC machining, automated heat treatment lines, and robotic welding to ensure the highest precision and consistency in hook production. Each heavy duty lifting hook for crane is crafted with meticulous attention to geometry, hardness, and load-path optimization to minimize wear and extend service life.

Before shipment, every hook is subjected to:

• Non-destructive Testing (NDT)
  Includes ultrasonic inspection and magnetic particle testing to detect internal and surface flaws.

• Proof Load Testing
  Each hook is load-tested up to 1.25–1.5 times the rated capacity to guarantee structural integrity and performance under real-world conditions.

• Material Certification & Traceability
  All materials come with full traceability and comply with international certifications such as ISO 9001, CE, SGS, and Lloyd’s Register (upon request).
