Product Specification

Product Overview

The S6 Screw Pin Bow Shackle is a high-strength alloy steel lifting and rigging component designed for connecting compatible lifting equipment, wire rope slings, chain slings, and other rated rigging accessories.

The bow-shaped body provides a wider connection area than a straight or dee shackle, making this configuration suitable for applications where loads or multiple rigging components need to be connected through the shackle body.

The screw pin design allows convenient installation and removal while maintaining a secure mechanical connection when correctly installed. The shackle can be supplied in different sizes and Working Load Limits (WLL) for industrial lifting, cargo handling, construction, marine, and general rigging applications.

CE certification and inspection documentation can be supplied according to the applicable product specification and customer requirements.

Product Features

1. High Strength Alloy Steel Construction

The S6 bow shackle is manufactured from alloy steel selected for lifting and rigging applications.

Key characteristics include:

1.High mechanical strength

Manufacturing Process

1. Alloy Steel Material Inspection

Raw alloy steel is checked according to the required material specification.

2. Forging

The shackle body is forged to form the required bow configuration.

3. Heat Treatment

Controlled heat treatment can be applied to achieve the required mechanical properties.

4. Machining

The pin hole, screw thread, and other critical dimensions are machined according to specification.

5. Surface Treatment

The shackle is galvanized, painted, or otherwise treated according to the selected finish.

6. Dimensional Inspection

Body dimensions, pin dimensions, thread engagement, and other critical areas are inspected.

7. Load Testing

Proof load testing can be performed according to applicable standards and customer requirements.

8. Marking & Final Inspection

WLL, size, manufacturer identification, and other required markings are checked before shipment.

How to Select the Correct S6 Bow Shackle

Before purchasing a screw pin bow shackle, buyers should confirm:

1. Working Load Limit

Select the WLL based on the maximum load and lifting configuration.

2. Shackle Size

Confirm the required body width, pin diameter, and connection dimensions.

3. Connection Hardware

Check compatibility with wire rope, chain, hooks, master links, or other components.

4. Lifting Configuration

For multi-leg lifting systems, consider sling angle and load distribution.

5. Surface Treatment

Choose galvanized or painted finishes according to the operating environment.

6. Certification

Confirm whether CE documentation, proof load testing, or third-party inspection is required.

Safety Considerations

For professional lifting applications:

1.Check the WLL marking before use

2.Inspect the shackle body and pin

3.Ensure the screw pin is fully engaged

4.Confirm the pin and body are compatible

5.Do not side-load unless specifically permitted

6.Avoid shock loading

7.Do not exceed the rated WLL

8.Use compatible lifting accessories

9.Remove damaged or deformed shackles from service

The WLL of the complete lifting assembly is determined by the applicable configuration and the capacity of its weakest rated component.
