Core Features & Avantages

• 1. Force sans compromis & Durabilité:

  • Matériaux premium: Forgé en acier en alliage à haute tension (Par exemple, Grade P, Q, S, or equivalent per FEM/DIN/ISO standards) for exceptional strength-to-weight ratio and resistance to deformation.
  • Construction robuste: Precision forging ensures superior grain structure flow, minimizing stress points and maximizing fatigue life under repeated heavy loads.
  • Résistance à la corrosion: Options include high-quality zinc plating (electro or hot-dip galvanizing), specialized coatings, or stainless steel variants for harsh environments (marin, chimique).

• 2. Sécurité améliorée & Reliability:

  • Tests rigoureux: Every hook undergoes Non-Destructive Testing (NDT – Magnetic Particle, Colorant pénétrant) and proof load testing (typically 1.5x – 2x SWL) to guarantee structural integrity and compliance with safety regulations (ISO 4301, Femelle 1.001, ASME B30.10, DEPUIS 15400).
  • High Safety Factor: Designed with a significant safety margin exceeding minimum regulatory requirements (Par exemple, 4:1, 5:1, or higher depending on classification).
  • Secure Latch Options: Reliable spring-loaded safety latches or robust bolt-type latches included as standard to prevent accidental load disengagement.

• 3. Optimized Performance:

  • Low Friction & Opération en douceur: Precision-machined throat and saddle points minimize friction with slings and rigging, reducing wear and ensuring smooth load movement.
  • Reduced Weight (Where Applicable): Advanced forging techniques and design optimization result in lighter hooks without sacrificing strength, improving crane efficiency.
  • Rotation Options: Available in fixed eye, standard rotation (plain bush/bearing), or low-friction sealed bearing rotation models (up to 360°) for effortless load positioning and reduced wire rope twisting.

• 4. Versatility for Every Task:

  • Comprehensive Range: Choose from various hook types:
    • Forged Single Hooks: Standard duty to ultra-heavy duty (SWL from 1 tonner à 500+ tonnes).
    • Forged Ramshorn Grue double: Ideal for balanced lifting with two sling legs (SWL from 1 tonner à 300+ tonnes).
    • Laminated Hooks: Multiple steel plates for specific high-impact or specialized applications.
  • Multiple Shank Configurations: Eye hooks, Clevis hooks, and hooks compatible with Weihua’s advanced trolley systems.
