Накладні специфікації гачка крана

When it comes to overhead cranes, one of the most critical components is the crane hook. The overhead crane hook specification determines the load handling capability, безпека, and efficiency of the entire lifting system. У цьому блозі, we’ll explore the essential specifications, types, стандарти, and selection tips for Над головою крана гачка to help you make an informed decision.

What is an Overhead Crane Hook?

An overhead crane hook is a device used to attach and lift loads during crane operation. It connects the load to the crane via slings, ланцюги, or lifting devices. The hook must be designed and manufactured according to precise engineering standards to handle the required capacity safely.

Key Overhead Crane Hook Specifications

1. Навантажувальна здатність

• The most important specification.

• Indicates the maximum weight the hook can safely lift.

• Must match or exceed the rated capacity of the crane system.

2. Тип гачка

• Одиночний гачок: Used for light to medium loads; economical and common.

• Кран подвійний гачок: Suitable for heavy-duty applications with better load balance.

• Forged Hook: Strong and reliable; made from high-quality alloy steel.

• Laminate Hook: Constructed from laminated steel plates; ideal for very heavy loads.

3. Матеріал

• Usually made of high-tensile alloy steel for strength and fatigue resistance.

• Heat-treated and forged to enhance durability and safety.

4. Відкриття горла

• The distance between the tip and the back of the hook.

• Must be checked regularly for deformation or wear.

5. Hook Dimensions

Common dimensions include:

• Eye diameter

• Neck width

• Overall height and width

• Radius of curvature

These dimensions must comply with standards like DIN, ISO, ASME B30.10, or other regional regulations.

6. Засувка

• A safety feature to prevent accidental load release.

• Mandatory in most industrial settings.

7. Rotation Capability

• Some hooks are designed to rotate 360° to help position loads more precisely.

Relevant Standards and Certifications

To ensure safety and compliance, overhead crane hooks should follow international or national standards such as:

• ASME B30.10 – Safety standards for hooks.

• З 15401 / З 15402 – German standards for crane hook designs.

• ISO 7597 – Standard for lifting hooks.

These standards specify material, load limits, inspection intervals, and manufacturing tolerances.

How to Select the Right Crane Hook?

1. Determine Load Requirements: Know the maximum weight and type of loads.

2. Check Crane Compatibility: Ensure the hook matches the crane’s lifting mechanism.

3. Consider Application Environment: Heat-resistant or corrosion-resistant hooks may be needed in foundries or chemical plants.

4. Verify Standards Compliance: Always choose hooks certified by recognized safety bodies.

Conclusion

Understanding overhead crane hook specifications is crucial for maintaining a safe and efficient lifting operation. From load capacity and material to standards compliance and safety features, each detail plays a vital role in performance. Always consult with a professional manufacturer or engineer when selecting crane hooks for your system.
