20 Ton Crane Hook Dimensions

When it comes to heavy lifting operations, the crane hook plays a critical role in ensuring safe and efficient material handling. For lifting capacities like 20 tấn, the design and dimensions of the crane hook become even more vital. In this blog post, we’ll explore the 20 ton crane hook dimensions, their importance, typical specifications, and how to choose the right hook for your application.

What Is a 20 Ton cần cẩu móc?

A 20 ton crane hook is an industrial-grade lifting component designed to bear loads up to 20 metric tons (20,000 kg). It is commonly used in overhead cranes, gantry cranes, and jib cranes in heavy-duty industries such as steel plants, shipyards, warehouses, and construction sites.

Why Are Hook Dimensions Important?

The dimensions of a crane hook directly affect:

• Load distribution

• Safety and durability

• Compatibility with slings, shackles, and loads

• Compliance with standards (DIN, Nữ, ISO)

Incorrect dimensions can lead to poor performance, excessive wear, or even accidents.

Standard 20 Ton Crane Hook Dimensions (Approximate)

Tham số	Single Hook	Double Hook
Rated Capacity	20 Ton cần cẩu móc	20 tấn
Vật liệu	High-strength alloy steel	High-strength alloy steel
Mở đầu (B)	85 – 100 mm	75 – 90 mm
Hook Height (H)	400 – 500 mm	350 – 450 mm
Hook Width (W)	200 – 250 mm	180 – 230 mm
Shaft Diameter (D)	75 – 90 mm	70 – 85 mm
Throat Depth	60 – 80 mm	60 – 75 mm
Cân nặng	~55 – 70 kg	~60 – 80 kg

Note: Actual dimensions may vary depending on the hook type (forging or laminated), nhà sản xuất, and standards used.

Types of 20 Ton Crane Hooks

• 1. Forged Crane Hooks

  • Manufactured from a single piece of high-strength steel

  • Common in general overhead lifting applications

• 2. Laminated Crane Hooks

  • Built by stacking steel plates

  • Ideal for extreme environments or when a backup load path is needed

• 3. Single Hook vs. Double Hook

  • Single Hook: Simple structure, used in one-direction lifting

  • Crane Double Hook: Symmetrical lifting, reduces lateral load stress

Choosing the Right 20 Ton cần cẩu móc

When selecting a 20 Ton cần cẩu móc, consider:

• 1. Application environment (temperature, humidity, corrosion)

• 2. Load characteristics (static or dynamic load)

• 3. Operational frequency

• 4. Compliance with OSHA, ISO, or DIN standards

• 5. Compatibility with hoisting equipment

Crane Hook Safety Tips

• 1. Perform regular inspection and maintenance

• 2. Replace hooks showing signs of deformation, wear, or cracks

• 3. Ensure the hook latch is always in place

• 4. Use the hook within its rated capacity

Conclusion

Understanding 20 ton crane hook dimensions is essential for safe and efficient lifting operations. By choosing the right hook size and type based on your industrial needs, you ensure the longevity of your lifting equipment and the safety of your operation. Always consult with a reputable manufacturer or supplier to confirm exact specifications and standards compliance.
