Episode 4: Slinging & Loading Methods – Safe Practices
Safe rigging is essential to prevent accidents, equipment damage, and ensure operational efficiency in lifting operations. Proper slinging and loading techniques protect workers and property when handling heavy loads.
1. Definition of Slinging |
Slinging refers to the process of attaching and securing loads to lifting equipment, such as cranes or hoists, by using slings (wire rope, chain, or synthetic slings).
It covers selecting the appropriate sling type, determining the correct hitch and ensuring the load is balanced and stable throughout the lift.
2. Common Slinging Methods |
The principal methods include vertical hitch, choker hitch, and basket hitch:
Vertical Hitch: A single leg of the sling connects the load directly to the lifting hook.
Choker Hitch: The sling forms a loop around the load, tightening under weight to secure it.
Basket Hitch: The sling supports the load from two points, providing stability and balance.
Slings must be chosen based on load type, weight, and required stability for the operation.
3. Safe Loading Practices |
Never exceed the rated capacity of the sling; always consult the manufacturer's charts for capacity adjustments based on the load angle and configuration.
Keep sling angles ideally above 45°, and preferably above 60°, for safest load distribution.
Slings must be protected from sharp edges or rough surfaces using pads to prevent abrasion or cutting.
Always inspect slings before use for wear, damage, or distortion, and remove defective gear from service immediately.
During lifting, make sure that personnel stand clear of suspended loads.
4. Wrong Practices to Avoid |
Never knot, twist, or kink sling legs to adjust length or tension.
Do not wrap the hoist rope directly around the load; always use appropriate slings and hooks.
Avoid lifting with sling angles less than 30°, as they drastically reduce safe capacity and increase risk of failure.
Never side, back, or tip load hooks; they must support loads as designed.
Do not use damaged, distorted, or improperly assembled slings and accessories.
Petrolift Tips: |
Always verify that slings and rigging hardware are clearly marked with their working load limits, and only used for their intended purpose. Continuous training and maintaining a strong safety culture are key to reducing accidents in rigging operations.
