G80 Clevis Shortening Grab Hook European Type Lifting Hook Rigging Accessories Sling Hook

Clevis Shortening Grab Hook Product Advantage

1. Quick adjustment to improve efficiency

✅  No disassembly required: By directly fixing the chain or sling with a hook, the length can be quickly adjusted, eliminating the tedious steps of repeated disassembly and assembly of traditional shackles.

✅  Save time: Especially suitable for scenarios that require frequent changes in lifting height (such as construction and port operations), significantly reducing downtime.

2. High strength&super durability

✅  High quality materials: Made of high-strength alloy steel (such as Grade 80/100), heat-treated and precision forged, with high tensile strength, wear resistance and impact resistance.

✅  Anti corrosion treatment: surface galvanized or sprayed with anti-corrosion coating, suitable for harsh environments such as humidity, salt spray, etc. (such as offshore operations).

3. Safe and reliable, reducing risks

✅  Anti decoupling design: Some models are equipped with safety locks or spring locking mechanisms to prevent accidental loosening under load.

✅  Clear load identification: Clearly label the Working Load Limit (WLL) to avoid manual overloading operations and comply with safety standards such as OSHA and ASME.

4. Multi functional adaptability

✅  Strong compatibility: It can be used in conjunction with various lifting devices such as chains, wire ropes, and synthetic slings, and is suitable for different lifting needs.

✅  Flexible installation: The U-shaped shackle design facilitates the connection of lifting rings, crane lifting points, or other fixed devices, making installation convenient.

1. Construction & Heavy Lifting

• Tower Cranes & Mobile Cranes – Quickly adjust lifting chain lengths when positioning steel beams, concrete panels, or prefab modules.

• Scaffolding Assembly – Secure and tension support chains during high-altitude work.

• Bridge & Roadwork – Ideal for adjusting suspension points during girder installations.

Advantage: Saves time compared to traditional chain-and-shackle systems.

2. Marine & Offshore Operations

• Shipbuilding/Dry Dock – Adjust lifting slings when moving hull sections or engines.

• Port Cargo Handling – Secure containers or heavy machinery during loading/unloading.

• Offshore Rigging – Corrosion-resistant models withstand saltwater exposure.

Advantage: Hot-dip galvanized options resist rust in harsh marine environments.

3. Mining & Heavy Machinery

• Dragline & Excavator Rigs – Shorten or extend drag chains efficiently.

• Underground Mining – Reliable for lifting ore buckets, ventilation systems, and equipment.

• Quarry Operations – Adjust wire rope lengths when handling large stone blocks.

Advantage: High-grade alloy steel (Grade 80/100) handles extreme dynamic loads.

4. Energy & Wind Power

• Wind Turbine Installation – Adjust lifting chains during nacelle or blade positioning.

• Power Line Maintenance – Secure utility poles or transformers during aerial lifts.

• Oil & Gas Rigging – Used in derrick assembly and pipeline handling.

Advantage: Safety latch prevents accidental release in high-wind conditions.

5. Transportation & Logistics

• Flatbed Truck Securing – Fasten heavy equipment or cargo with chains.

• Railcar Loading – Quickly tension tie-downs for locomotives or freight.

• Warehouse Heavy Lifting – Adjust hoist chains for machinery relocation.

Advantage: Reduces manual labor in load adjustments.

6. Agriculture & Forestry

• Tractor Implements – Adjust lift arm chains for plows or harvesters.

• Logging Operations – Secure timber bundles during loading/offloading.

Advantage: Durable construction withstands mud, debris, and weather exposure.

7. Emergency & Rescue

• Disaster Recovery – Rapid rigging for debris removal or vehicle recovery.

• High-Angle Rescue – Adjustable anchor points for rope systems.

Advantage: Quick-release options available for urgent scenarios.

1. What is the main purpose of a Clevis Shortening Grab Hook?

✅ Answer: It allows quick adjustment of chain or sling length without disassembly, improving efficiency in rigging and lifting operations.

2. What materials are used in manufacturing?

✅ Answer: High-grade alloy steel (typically Grade 80 or 100), drop-forged and heat-treated for strength. Surface treatments include hot-dip galvanizing or paint for corrosion resistance.

3. What’s the difference between Grade 80 and Grade 100?

✅ Answer:

• Grade 80: Strong, general-purpose (construction, logistics).

• Grade 100: 25% stronger, lighter, and more impact-resistant (ideal for mining, heavy industry).

4. How do I know which size to choose?

✅ Answer: Match the Working Load Limit (WLL) to your load requirements and ensure the hook’s throat opening fits your chain/wire rope diameter (see product specs).

5. What’s the lifespan of this product?

✅ Answer: Depends on usage—properly maintained hooks in moderate conditions last 5–10 years. Replace if wear exceeds 10% of original dimensions.
