G2130 lifting shackle Product Advantage

1、High strength:

After careful design and manufacturing, it can withstand large tensile and impact forces, meeting the strength requirements of various lifting and hoisting operations.

2、Corrosion resistance:

The surface can be treated with immersion paint, spray paint, electroplating, hot plating, spray coating, etc. to give it good corrosion resistance, suitable for different working environments, such as humid marine environments or industrial sites with corrosive media.

3、Durability:

High quality materials and advanced manufacturing processes, as well as strict quality testing, make G2130 shackles have a long service life and can withstand frequent use and harsh working conditions.

4、Safe and reliable:

Each shackle is permanently marked with information such as the working load limit and grade, making it easy for users to confirm and select. Some large tonnage shackles will also be equipped with RFID chips for easy management and traceability. In addition, its design complies with relevant safety standards such as ASME B30.26, and undergoes rigorous testing, including fracture tests, fatigue tests, etc., to ensure safety during use.

Pre - use Inspection

• Check Rated Load: Clearly identify the rated load and specifications of the G2130 shackle to ensure it is suitable for the actual lifting task. The rated load is usually marked on the shackle body, and it is necessary to confirm that the load to be lifted does not exceed this value.

• Inspect for Damage: Carefully check whether there are defects such as cracks, deformation, or corrosion on the shackle body and pin. Cracks can be observed visually, and any visible cracks should be scrapped immediately. Deformation, such as obvious bending or distortion of the shackle body, or inability of the pin to rotate flexibly, also indicates that the shackle cannot be used.

Installation and Connection

• Correct Connection Positions: The shackle body and pin should be connected to the appropriate positions respectively. Usually, the body is connected to the wire rope or chain, and the pin bolt is connected to the hook. The connection direction should not be wrong.

• Ensure Centralized Force Application: The connection point with other rigging, that is, the force - bearing point, should be located in the middle of the shackle body and pin (the top of the buckle). It should be parallel to the direction of the chain or hook, rather than referring to the horizontal line of the ground, to avoid the shackle bearing lateral force.

• Connect with Wire Rope: When used in combination with a wire - rope socket, the cross - pin side should contact the wire - rope thimble (the end 套在鸡心环的一端). The body of the shackle is connected to the wire rope on the other side. If the direction is reversed, friction will occur during the tightening process, and the cross - pin is likely to loosen.

Lifting Operation Precautions

• Control the Angle: When the shackle bears two - leg rigging, the included angle between the two legs should not be greater than 120 degrees. If it is a multi - leg combined rigging, the angle formed between each leg will affect the safe load, and a suitable angle should be selected through calculation to avoid overloading the shackle.

• Keep the Force in the Center: The shackle should support the load correctly, that is, the acting force should be along the axis of the center line of the shackle to avoid bending, unstable loads, and overload. It is necessary to avoid the eccentric load of the shackle, otherwise, it will affect the lifting safety and may cause the shackle to be damaged prematurely.

• Avoid Impact and Collision: During the lifting process, large - scale impact and collision are not allowed, and the movement should be carried out at a constant speed to prevent the shackle from being damaged due to sudden large - force impacts.

Post - use Maintenance and Inspection

• Regular Inspection: According to the frequency of use and the severity of working conditions, a reasonable regular inspection cycle should be determined, which should not be less than half a year and not more than one year. Check whether there are cracks, deformation, wear, or corrosion on the shackle body and pin. If the wear amount of any surface of the shackle body and pin exceeds 10% of the nominal size, it should be scrapped immediately.

• Proper Storage: When not in use, the shackle should be stored in a dry and well - ventilated area. For long - term storage, ensure that the surface of the shackle is clean and free of dirt or grime, and avoid exposing it to heat or direct sunlight. Keep it away from corrosive chemicals to prevent corrosion and damage to the shackle.

Q1：How to judge if a shackle is "overloaded" and needs to be scrapped?

• Signs of overload:

• Visible deformation: The shackle body is bent, the pin is swollen, or the opening between the shackle legs is widened.

• Cracks: Even small cracks (visible to the naked eye or detected by non-destructive testing like magnetic particle inspection) indicate structural failure.

• Reduced functionality: The pin cannot rotate smoothly, or the shackle cannot be properly connected to rigging due to deformation.

• Rule: Any shackle showing the above signs must be immediately scrapped. Do not attempt to repair (e.g., straightening, welding) as this will compromise safety—overloaded shackles lose their rated load capacity and pose a high risk of sudden failure during lifting

Q2:Can the G2130 shackle be used in high-temperature or corrosive environments?

• High-temperature environments: G2130 shackles are typically made of carbon steel. Avoid continuous use in temperatures exceeding 200°C, as high heat can weaken the material’s tensile strength. For high-temperature applications, use shackles specifically designed for heat resistance (e.g., alloy steel models).

• Corrosive environments: Standard G2130 shackles have basic anti-rust properties but are not suitable for long-term use in highly corrosive environments (e.g., seawater, chemical plants). In such cases:

• Choose shackles with enhanced anti-corrosion treatments (e.g., hot-dip galvanizing, stainless steel).

• Increase maintenance frequency: Clean and apply anti-rust oil regularly to slow corrosion.

Q3:Can two shackles be "stacked" (connected in series) to increase load capacity?

• No. Stacking shackles does not increase the total load capacity; instead, it creates unstable force distribution. The load will concentrate on one shackle (depending on connection angle), leading to overload of the weaker one.

• Correct approach: Use a single shackle with a rated load matching or exceeding the total load, or use multi-leg rigging with a single shackle designed for the combined load.
