Connectors for Lifting and Towing
The bow shackle is a metal connection device, named for its bow-and-arrow shape. It is also known as a horseshoe shackle, B-type shackle, or bow-shaped clasp, and is primarily used in lifting and towing operations. It consists of a bow-shaped body, bolt pin, and nut.
🛡️
Premium Material
Made of high-strength alloy steel or stainless steel, with hot-dip galvanized or electroplated finishes for superior corrosion resistance.
📏
Standard Compliance
Manufactured according to National, American, and Japanese standards with safety factors ranging from 4x to 6x.
⚓
Versatile Load
Rated loads range from 0.33 tons to 150 tons, with specialized heavy-duty models exceeding 1000 tons.
This device features a circular design that reduces stress concentration compared to D-type shackles and accommodates multi-directional loads. For both marine and land applications, it is available in various types, including lifting shackles, anchor chain shackles, and safety shackles. Applications include power generation, metallurgy, machinery, and construction. When using, strictly follow the working load limit, regularly check for deformation, cracks and wear, and keep the pins clean and lubricated.
Frequently Asked Questions
What are the main components of a bow shackle?
A standard bow shackle consists of a bow-shaped metal body, a bolt pin, and a nut for secure fastening.
Why choose a bow shackle over a D-type shackle?
The circular bow design reduces stress concentration and is better suited for multi-directional loads or larger attachments.
What materials provide the best durability for these connectors?
High-strength alloy steel and stainless steel are preferred, especially when hot-dip galvanized to resist rust and corrosion in marine environments.
What is the safety factor for bow shackles?
Depending on the specific type and production standard, safety factors typically range from 4x to 6x the working load limit.
Which industries commonly use bow shackles?
They are widely used in power generation, metallurgy, heavy machinery, construction, and both marine and land-based towing operations.
How should bow shackles be maintained?
Regularly inspect for any deformation, cracks, or wear. It is essential to keep the pins clean and well-lubricated while strictly adhering to the rated load limits.
