Double Girder Crane Hook

Double girder crane hooks offer superior stability and load control compared to single girder alternatives, making them ideal for high-demand environments. Their modular design allows customization to meet specific operational requirements, while advanced safety features minimize downtime and maintenance costs.

Double Girder Crane Hook Key Features and Advantages

• 1. Robust Construction:
  • Manufactured from high-strength materials such as carbon steel, alloy steel, or stainless steel, ensuring durability and resistance to wear, corrosion, and fatigue.
  • Forged or laminated designs optimize stress distribution, enhancing load-bearing capacity and longevity.
• 2. Enhanced Lifting Capability:
  • Supports lifting capacities ranging from 5 to 550 tons, depending on crane specifications.
  • Compatible with double girder cranes featuring spans up to 35.5 meters, enabling coverage of large work areas.
• 3. Safety Compliance:
  • Adheres to international standards, including ISO 12100 (safety of machinery) and ISO 4301 (crane classification).
  • Equipped with safety latches, anti-detachment mechanisms, and load-limiting devices to prevent accidents.
• 4. Versatility:
  • Suitable for diverse applications, including machinery assembly, steel coil handling, warehouse logistics, and power plant maintenance.
  • Works seamlessly with auxiliary equipment like magnets or grabs for specialized tasks.
• 5. Operational Efficiency:
  • Double girder design allows the hook to achieve greater lifting heights, maximizing vertical space utilization.
  • Top-running trolley systems reduce vibration and improve positioning accuracy.
