General Information

Care

Store Herc-Alloy 800 chain slings on A-frames or wall racks in a clean dry place.
Lightly oil Herc-Alloy 800 chain slings before prolonged storage.
Never heat-treat Herc-Alloy 800 chain slings.

Use

Always inspect a chain sling before use to ensure it is free from damage or wear.
Ensure that the load is evenly distributed on all sling legs.
Ensure that the chain is free of twists and is protected from any sharp corners on the load.
Commence the lift slowly, taking up the slack gradually.
When lowering, avoid the possibility of crushing the chain by ensuring that the load does not land on it.

Inspection

It is important to inspect chain slings regularly and that a record is kept for each chain sling. Chain sling inspection record cards are available from PWB Anchor Ltd and Herc-Alloy 800 chain and fitting distributors free of charge.
If necessary, clean the sling before inspection.
Every chain link should be individually inspected for signs of wear, twisting, stretching, nicks, or gouging, and any worn link measured to determine degree of wear.
Oblong links and hooks should be inspected at their loadbearing points for signs of wear or distortion, eg widening of hook throat opening.
Defective chain links or fittings should be clearly marked to indicate rejection, and the chain sling withdrawn from service until repaired.
Hammerloks should be inspected for any signs of wear at their loadbearing points, for excessive play of the load pin within the body halves and for impaired rotation of the body halves around the load pin. (Note: when reassembling a Hammerlok it is recommended that a new pin and stud assembly be used.)
Enter all results in the sling inspection record card.

Effects of Hazardous Conditions

Heat Conditions

The strength of all chain slings is adversely affected by heat so care must be exercised when using at elevated temperatures. Where temperatures are likely to be higher than 200ºC reductions in the working load limits of Herc-Alloy 800 slings should be applied.

Heat Treatment

Herc-Alloy 800 Chain & Fittings do not require periodic heat treatment and must never be heat treated.

Corrosive Conditions

Herc-Alloy 800 Chain & Fittings should not be used in acid or other corrosive environments.

Galvanising

Herc-Alloy 800 Chain & Fittings must never be hot dipped, mechanically galvanised or electroplated except by PWB Anchor.
Hot dipped galvanised slings must always have their working load reduced by 20%.

Temperature Reduction of Range °C WLL while heated
Up to 200 Nil

300–400 25%
Over 400 Do not use
