Core components and superior design of crane hooks with pulley block

1. High-Strength Forged Hook:

   • Matériel: Manufactured from high-tensile alloy steel (Par exemple, Grade 80, 100, or higher according to demand), forged under strict conditions for superior grain structure and strength.

   • Latch de sécurité à crochet de grue: Standard equipped with a robust, spring-loaded safety latch to securely retain slings, chains, or lifting devices, preventing accidental disengagement.

   • Precision Machining: Precision-ground throat and shank surfaces ensure optimal load distribution and secure seating of lifting accessories.

   • Finishes: Shot blasted and primed for corrosion protection. Optional galvanization (hot-dip or electro) available for severe environments.

2. Optimized Pulley Block (Sheave Assembly):

   • Sheaves: Machined from high-grade steel or ductile iron, featuring smooth, accurately grooved profiles to minimize rope wear and maximize efficiency. Sealed, lubricated anti-friction bearings ensure effortless rotation.

   • Rigging: Side plates and cheek plates are fabricated from high-strength steel plate, designed for rigidity and resistance to bending or distortion under load.

   • Bushing/Pin Assembly: Precision-machined pins running on durable bushings or bearings provide smooth articulation and long service life.

   • Efficiency: The multi-sheave design provides significant mechanical advantage, reducing the force required from the hoist motor and wire rope for lifting heavy loads.
