G80 Stainless Steel Chain Sling is a lifting assembly consisting of Grade 80 stainless steel chain and compatible lifting components. The sling configuration can be customized according to lifting requirements, including leg number, chain diameter, effective working length and end fittings.

Compared with conventional alloy steel Grade 80 chain slings, stainless steel G80 chain slings are selected for applications where corrosion resistance and surface cleanliness are required.

Product Structure

Available configurations:

Single Leg Chain Sling

Two Leg Chain Sling

Three Leg Chain Sling

Four Leg Chain Sling

Main components:

Grade 80 Stainless Steel Chain

Master Link

Connecting Link

Clevis Hook

Self-Locking Hook

Shortening Device

Working Conditions

The Working Load Limit (WLL) must not be exceeded during lifting operations.

The chain sling must be selected according to:

Load weight

Chain diameter

Number of loaded legs

Sling angle

Working environment

Multi-leg chain slings require correct angle selection because the load on each leg increases as the angle becomes larger.

Application Environment

G80 Stainless Steel Chain Sling is suitable for:

Marine lifting operations

Offshore maintenance

Food processing equipment handling

Chemical industry applications

Clean manufacturing environments

Corrosion-sensitive industrial lifting

Continuous Sling

Working Load Limit (WLL) for an endless chain sling configuration.

0° < a < 45°
The angle between the sling leg and the vertical is between 0° and 45°.

45° < a < 60°
The angle between the sling leg and the vertical is between 45° and 60°.

Factor
The load multiplier used to calculate the Working Load Limit for different sling configurations and lifting angles.

a
The angle between the sling leg and the vertical line.

(ton)
All values are expressed in metric tons and represent the maximum Working Load Limit (WLL).

Design Factor 4:1
The minimum breaking force of the sling assembly is at least 4 times its Working Load Limit (WLL).

90 Degrees

The sling is lifting vertically with no sling angle reduction.

60 Degrees / 45 Degrees / 30 Degrees

The angle between each sling leg and the horizontal plane. As the angle decreases, the sling capacity decreases.

Load Factor

A multiplier used to calculate the Working Load Limit based on the number of sling legs and the lifting angle.

WLL Values (lbs)
The numbers shown in the table represent the maximum Working Load Limit in pounds for each chain diameter and sling configuration.

Example:
For a 1/2" chain sling:

• 1-Leg Sling = 12,000 lbs

• 2-Leg Sling at 60° = 20,800 lbs

• 2-Leg Sling at 45° = 17,000 lbs

• 2-Leg Sling at 30° = 12,000 lbs

• 3 & 4-Leg Sling at 60° = 31,200 lbs

• 3 & 4-Leg Sling at 45° = 25,500 lbs

• 3 & 4-Leg Sling at 30° = 18,000 lbs

Note: The lifting angle shown in this table is measured from the horizontal. Smaller angles result in higher tension in each sling leg and lower overall lifting capacity.
