* Assumes the use of a 100% rated shortening hook.
For basket slings and engineered lifts, please consult AS 3775 Parts 1 or 2, accordingly.
The values expressed on this table exceed or meet the minimum requirements of AS 3775.2 and are stated in tonnes of 1000kg.
The above maximum working load limits are for general conditions of use to group classification of crane mechanisms of M3 as specified in AS1418.1 WLL must never be exceeded, even at angles less than 60 degrees or event if the load is flexible. For other than general conditions of use the WLL will be derated to conform to the group classification of crane mechanisms as specified in AS1418.1.
DISCLAIMER: This Working Load Limit Chart is provided as a guide only. When preparing lifting calculations please check the relevant Australian Standard.
- Store Grade 80 Chain Slings on A-frames or wall racks in a clean dry place.
- Lightly oil Grade 80 Chain Slings before prolonged storage.
- Never heat-treat Grade 80 Chain Slings.
- Always inspect 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 the chain or any component of the sling.
- It is important to inspect Grade 80 Chain Slings regularly and that an inspection record is kept for each chain sling.
- If necessary, clean the sling before inspection.
- Every chain link should be individually inspected for signs of wear, twisting, stretching, nicks or gouging. Any worn link should be measured to determine degree of wear.
- Oblong links and hooks should be inspected for signs of wear or distortion, for example 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- Defective chain links or fittings should be clearly marked to indicate rejection and the chain sling withdrawn from service until repaired.
- Connectors should be inspected for any signs of wear at their load bearing points, for excessive play of the load pin within the body halves and for impaired rotation of the body halves around the load pin.
