How to Choose the Right 4 Leg Lifting Sling for Your Operation

Published on: Sep  24, 2025 | Source: chen | Hits: 0

Selecting the right 4 leg lifting chains or a 4 leg lifting sling is not just about capacity—it’s about matching the correct equipment to your specific working environment. With so many configurations available, choosing a 4 leg sling or a 4 point chain sling requires careful consideration of safety standards, chain grade, working angles, and attachment types. This article offers a complete buyer’s guide to help you avoid costly mistakes and ensure safe, efficient lifting operations.


Why Selection Matters

The wrong choice of 4 leg lifting sling can result in unsafe working conditions, reduced service life, and even serious accidents. Every project—from construction sites to shipyards—has unique lifting demands. By evaluating the right criteria, you ensure maximum productivity and long-term reliability.


Key Factors to Consider

1. Chain Grade

G80: Standard strength, widely used in construction and manufacturing.

G100: Higher load capacity at the same diameter, often chosen for heavy industry.

2. Sling Angle

A 4 point chain sling is sensitive to sling angle.

At wider angles, capacity reduces significantly.

Always check rated WLL charts before use.

3. End Fittings

Different hooks and connectors change the usability:

Grab hooks for secure hold on steel beams.

Self-locking hooks for safety when handling containers.

Foundry hooks for high-temperature environments

4. Surface Protection

Standard alloy steel: strong but may corrode if not maintained.

Galvanized or coated chains: recommended for humid, marine, or chemical environments.
