1、Excellent structural design

The bow shaped structure of the 2130 bow shaped release buckle can be considered a major highlight. Compared to other shapes, the bow design greatly expands the area of the load. In actual lifting operations, the weight of heavy objects is evenly dispersed, reducing local pressure on connecting ropes and chains, minimizing wear, and extending their service life. Taking the lifting of prefabricated panels on construction sites as an example, using 2130 bow shaped shackles can make the connecting ropes more evenly stressed, reduce the risk of rope breakage, and ensure safe and efficient lifting. This structure also provides convenience for multi-directional force application. In complex lifting environments, it can flexibly respond to tensile forces from different directions, maintain the stability of the connection, and avoid accidents caused by uneven force application.

2、High strength materials and craftsmanship support

The raw material for manufacturing 2130 bow shaped shackles is carefully selected high-quality alloy steel. This type of steel inherently possesses excellent strength and toughness. After initial forging, it undergoes heat treatment processes such as quenching and tempering to optimize its internal structure and significantly improve its comprehensive mechanical properties. After testing, its tensile strength and yield strength far exceed ordinary steel, and it can easily cope with the huge tensile and impact forces under high-intensity operations. Strictly following international standards (such as ISO 2415-2004) to control the production process, from raw material procurement to finished product delivery, multiple quality inspection processes are carried out to ensure that every 2130 bow shaped shackle is of high quality and reliable performance.

3、Excellent surface protection

The common 2130 bow shaped shackles often use hot-dip galvanizing surface treatment technology. Under high temperature, zinc liquid undergoes a chemical reaction with the surface of steel, forming a dense and strong layer of zinc iron alloy. This protective layer not only has excellent rust and corrosion resistance, but also can resist erosion for a long time even in humid and rainy outdoor environments, or in marine engineering and chemical industry scenes with high salt content and strong corrosiveness, delaying the process of detachment rust and aging, and reducing maintenance frequency and cost. Of course, if customers have special requirements, they can also customize other surface treatment solutions such as electroplating to adapt to specific usage environments.

4、Reliable security performance

Safety performance is of utmost importance for the 2130 bow shaped release buckle. Its test load can reach twice the ultimate working load, and the breaking load can be up to four times or even more than the ultimate working load. The safety factor is usually maintained between 4-6, providing sufficient redundancy for operational safety. The shackle is equipped with a safety nut and a split pin. During operation, the safety nut can effectively prevent loosening, and the split pin further locks the nut, eliminating the risk of nut detachment and ensuring a stable and reliable connection, greatly improving operational safety. In industries with extremely high safety requirements such as mining and bridge construction, the 2130 bow shackle, with its reliable safety performance, has become a key component to ensure the safety of workers and the smooth progress of projects.

Here is a detailed product parameters table for the G2130 Bow Shackle , organized for clarity and practical reference:

Product Applications of G2130 Bow Shackle

1. Construction and Infrastructure

• Heavy Lifting: Used to connect cranes, hoists, or cables with construction materials such as steel beams, precast concrete panels, and heavy machinery (e.g., excavators, bulldozers) during building construction, bridge erection, or tunnel excavation.

• Temporary Fixing: Secures temporary structures like scaffolding, formwork, or steel frameworks to ensure stability during construction.

2. Maritime and Offshore Engineering

• Shipbuilding and Repair: Connects lifting equipment to ship components (e.g., hull sections, engines) during assembly or maintenance.

• Offshore Platforms: Essential for mooring systems, lifting subsea equipment (e.g., pipelines, anchors), and securing cargo on oil rigs or wind farms, thanks to their corrosion resistance (via hot-dip galvanizing) in saltwater environments.

3. Logistics and Transportation

• Cargo Handling: Links chains, straps, or hooks to secure heavy cargo (e.g., containers, industrial machinery) on trucks, trains, or ships, preventing shifting during transit.

• Port Operations: Facilitates loading/unloading of bulk goods (e.g., coal, grain) or oversized items using cranes and forklifts.

4. Mining and Heavy Industry

• Mining Operations: Connects ropes or chains to lift ore, mining machinery (e.g., drills, crushers), or structural parts in underground or open-pit mines.

• Factory Assembly: Used in manufacturing plants to move heavy equipment (e.g., turbines, presses) during production line setup or maintenance.

5. Energy and Utilities

• Power Generation: Aids in lifting and installing components for power plants (e.g., generators, transformers) or renewable energy projects (e.g., wind turbine blades, solar panel structures).

• Utility Maintenance: Supports overhead line work, such as lifting poles or transformers during electrical grid installation or repair.

6. Rescue and Emergency Services

• Search and Rescue: Used by emergency teams to lift or move debris, vehicles, or structural wreckage during disaster relief (e.g., earthquakes, floods).

• Towing Operations: Connects towing cables to disabled vehicles or machinery in off-road or industrial settings.

1、Can G2130 bow shaped shackles be used horizontally or diagonally?

Sure, but please note that when subjected to lateral or diagonal forces, the actual load-bearing capacity may be lower than the rated load (the larger the angle, the lower the load-bearing capacity).

It is recommended that when used diagonally, the angle should not exceed 45 degrees; If the angle is too large (such as close to 90 °), the actual load needs to be reduced or a more suitable shackle model needs to be replaced.

2、Does the surface treatment method affect the service life?

meeting. Standard hot-dip galvanizing treatment can form a dense zinc layer, effectively resisting corrosion from moisture, salt, and chemicals, and extending the service life in outdoor, marine, and other environments (usually up to 5-10 years, depending on the severity of the environment).

If choosing electroplating or spraying, the rust prevention ability is weaker and more suitable for dry and indoor environments. Regular maintenance (such as repainting and rust removal) is needed to extend the service life.
