Crochet de grue au-dessus

Au cœur de chaque système de grue en tête fiable se trouve un composant critique: le grue. Weihua Group, a globally recognized leader in lifting equipment manufacturing, designs and produces overhead crane hooks that set the standard for strength, durabilité, sécurité, and precision in demanding industrial environments.

Weihua overhead crane hooks are forged or meticulously machined lifting components designed to securely connect the crane’s hoist mechanism to the load. They are the primary interface between your valuable cargo and the crane’s lifting power. Weihua offers a comprehensive range of hooks tailored to diverse lifting capacities, operational requirements, and international standards.

Caractéristiques clés & Benefits Of Overhead Crane Hook

• 1. Exceptional Strength & Durabilité:

  • Matériaux premium: Manufactured from high-tensile strength alloy steels (Par exemple, 35CRMO, 42CRMO, 34Cr2Ni2Mo – compliant with DIN/ISO standards).
  • Advanced Manufacturing: Utilizes precision forging processes (closed die forging) or high-quality machining, ensuring superior grain structure and material integrity compared to casting.
  • Construction robuste: Designed with optimal geometry to distribute stress evenly, minimizing fatigue and maximizing service life under heavy, repeated loads.

• 2. Sécurité sans compromis:

  • High Safety Factor: Designed and manufactured significantly above nominal working load limits (Wll), typically adhering to DIN, Femelle, ASME B30.10, or GB standards with safety factors of 4:1, 5:1, or higher as required.
  • Mandatory Proof Load Testing: Every hook undergoes rigorous 125% à 200% of WLL proof load testing before leaving the factory, guaranteeing structural integrity.
  • Latch Options: Standard or custom safety latches are available to prevent accidental disengagement of slings or lifting attachments.
  • Strict Quality Control: Production follows ISO 9001 quality management systems, ensuring consistency and traceability.

• 3. Precision Engineering & Reliability:

  • Accurate Load Path: Optimized throat opening and hook profile ensure smooth engagement with shackles and slings, preventing slippage and minimizing wear.
  • Smooth Rotation: Precision-machined swivel bearings (in swivel hooks) allow the load to rotate freely, preventing dangerous cable twisting and enabling precise load positioning.
  • Reduced Wear: Hardened and tempered contact surfaces, combined with precise machining, minimize wear on the hook saddle and tip.

• 4. Comprehensive Range & Personnalisation:

  • Wide Capacity Spectrum: Available from small capacities (Par exemple, 1 tonne) up to very heavy-duty applications (500 tons and beyond).
  • Diverse Types:
    • Fixed Hooks: Simple, robust design for straightforward lifting.
    • Swivel/Rotating Hooks: Essential for applications requiring load rotation.
    • Crows Ramshorn (Foundry Hooks): Designed for specialized applications like foundry work with molten metal ladles.
    • Crochets pour les yeux: For specific mounting configurations.
    • Specialty Hooks: Including anti-sway hooks, tandem hooks, and custom designs for unique needs.
  • Custom Solutions: Weihua engineers can design hooks to meet specific dimensions, capacities, mounting requirements, or environmental conditions (Par exemple, extreme temperatures, corrosive atmospheres).

• 5. Conformité mondiale & Certification:

  • Manufactured to meet or exceed major international standards: DEPUIS 15401/15402, Femelle 1.001, ASME B30.10, GB / T 10051, ISO 7597, etc..
  • CE Marking available for the European market.
  • Full certification packages including Material Certificates, Heat Treatment Records, NDT Reports (Magnetic Particle/Ultrasonic Testing), and Proof Load Test Certificates.
