Custom Lifting Chain Slings – Tailored Engineering for Complex Lifting Projects

Custom lifting chain slings are essential for industries that handle oversized, irregular, or heavy components requiring precise and safe lifting. Unlike standard slings, custom-made assemblies are designed based on load geometry, lifting points, working load limit (WLL), angle factors, and environmental conditions.

At TOPONE CHAIN, we specialize in engineering G80 and G100 custom lifting chain slings to meet exact project requirements in construction, offshore lifting, mining, manufacturing, heavy machinery handling, and more.

Our slings combine high-tensile alloy steel, advanced heat treatment, and certified components to ensure maximum strength, durability, and safety in every lift.

Why Custom Chain Slings Matter

Businesses choose custom lifting chain slings because standard off-the-shelf slings often cannot meet the demands of:

✔ Irregular load shapes

Steel beams, machinery housings, large molds, turbines, ship components.

✔ Precise lift-point matching

Adjusting sling length to match multiple lifting points for balanced load distribution.

✔ Harsh working environments

High-temperature mills, offshore rigs, chemical exposure zones.

✔ Increased safety requirements

Custom slings allow operators to reduce risk through exact design and load factor calculations.

✔ Multi-leg lifting configurations

1-leg, 2-leg, 3-leg, or 4-leg assemblies engineered to precise WLL specifications.

Custom slings ensure that every lift is compliant, controlled, and safe — even under the most demanding conditions.
