Single Girder Crane Hook

The Single Girder Crane Hook is the critical endpoint of your overhead lifting system, designed to securely connect loads to single girder bridge cranes. Engineered for durability, safety, and versatility, this robust component ensures efficient material handling in workshops, warehouses, assembly lines, and manufacturing facilities.

Product Classification and Structural Features

By Manufacturing Process

1. Forged Crane Hook

• Material: Made of high-quality low-carbon killed steel (e.g., 20# steel, 16Mn) or low-carbon alloy steel, annealed for superior stress resistance.
• Types:
  • Single Hook: Suitable for cranes under 75 tons, simple structure, and easy operation.
  • Double Hook: Symmetrical force design, higher load capacity, ideal for cranes over 75 tons.

2. Laminated Hook (Stacked Hook)

• Material: Composed of multiple Q235 or 16Mn steel plates (thickness ≥20mm) riveted together, ensuring high safety.
• Types:
  • Single Hook: Primarily used in casting cranes; operational even if some plates are damaged.
  • Crane Double Hook: Suitable for general-purpose cranes over 100 tons, with redundant design for enhanced reliability.

By Functional Characteristics

• 1. Enclosed Hook: High safety and load capacity but complex installation.
• 2. Semi-Enclosed Hook: Balances safety and convenience, easier installation/disassembly.
• 3. Electric Rotary Hook: Integrates rotation function for container handling, improving space utilization and operational efficiency.

Single Girder Crane Hook Core Technical Parameters

Parameter	Specification

Single Girder Crane Hook Product Advantages

• 1. High Safety
  • Strict adherence to international/national standards; passes material inspection, load testing, and NDT (magnetic particle, ultrasonic).
  • Anti-dropping latch and high-strength materials ensure zero accidents.
• 2. Durability and Reliability
  • Forged hooks annealed for fatigue resistance; laminated hooks with redundant design allow continued use if partial damage occurs.
  • Smooth, crack-free surface with corrosion resistance for extended lifespan.
• 3. Versatility
  • Multiple types (single/double hook, enclosed/semi-enclosed) for loads 1–200 tons and diverse scenarios.
  • Electric rotary hooks optimize container handling and space utilization.
• 4. Compliance and Certification
  • ISO 9001 certified and inspected by China’s National Special Equipment Inspection Center.

Single Girder Crane Hook Applications

• 1. Industrial Manufacturing: Lifting equipment in machinery, metallurgy, and automotive assembly.
• 2. Logistics and Warehousing: Container handling, cargo sorting, and warehouse management.
• 3. Construction: Steel structure installation, building material transport, and construction equipment lifting.
• 4. Special Environments: High-temperature, corrosive, or confined space operations (customizable designs available).

After-Sales Service

• 1. Quality Assurance: Product certification, inspection marks, and unique production numbers for traceability.
• 2. Regular Inspection: Annual comprehensive checks recommended, including surface inspection, dimension measurement, and load testing.
• 3. Maintenance and Replacement: Rapid replacement of faulty parts; individual laminated hook plates can be replaced to reduce costs.
• 4. Technical Support: Professional team offers installation guidance, training, and troubleshooting.

The single girder crane hook combines high safety, durability, and adaptability, making it an indispensable component for modern industrial lifting. Whether for standard operations or demanding environments, it delivers reliable solutions to enhance efficiency and safety.
