Episode 5: Load Control, Operation & Final Safety Checks
This is the final episode in the “Safe Rigging Series” presented by Petrolift. In this episode, we close the safety loop by learning how to maintain control of the load, follow correct operating practices, and perform final safety checks before, during, and after every lift
1. Load Control – Understanding the Risk |
Controlling the load during lifting operations is the foundation of safe rigging. An uncontrolled load means uncontrolled risk — swinging, rotation, or sudden movement can cause injury, equipment damage, or even catastrophic accidents.
Positive load control means keeping the load steady, balanced, and predictable from the moment it leaves the ground until it reaches its destination.
2. Operating Practices - The Gold Rules of Rigging |
Whenever any sling or rigging gear is used, the following best practices must always be observed:
1. Do not use damaged or defective slings.
2. Never shorten or lengthen a sling by knotting or twisting.
3. Do not kink sling legs.
4. Never exceed the rated load capacity.
5. When using a basket hitch, balance the load to prevent slipping.
6. Securely attach the sling to the load.
7. Protect slings from sharp edges, corners, or abrasive surfaces.
8. Be alert for snagging during lifting or lowering.
9. Keep all personnel clear of suspended loads.
10. Never place hands or fingers between the sling and the load.
11. Avoid shock loading — always lift smoothly.
12. Do not pull a sling from under a load while it’s resting on it.
3. Inspection - Before Every Use |
Every sling, fastening, and attachment must be inspected daily by a competent person. Additional inspections should be performed whenever conditions warrant — such as after overload, exposure to heat, or visible damage.
Any damaged or defective item must be immediately removed from service.
4. Wire Rope Clips - How to Install Correctly |
One of the most common rigging components is the wire rope clip (U-bolt type). Incorrect installation can reduce rope efficiency and lead to failure.
Golden Rule: Never saddle a dead horse — always place the saddle on the live (load-bearing) side of the rope.
Never use malleable clips for critical applications. Use forged clips instead.
Installation Steps
Apply the first clip one base width from the dead end.
Apply the second clip as near the thimble as possible.
Space all remaining clips evenly between the first two.
This ensures maximum grip strength and reduces the risk of slippage during lifting.
Minimum Number of Clips Required:

3/16 | 2 |
1/4 | 2 |
5/16 | 2 |
3/8 | 2 |
7/16 | 2 |
1/2 | 3 |
9/16 | 3 |
5/8 | 3 |

Petrolift Tips: |
Safe rigging doesn’t end when the load is lifted — it ends when it’s safely placed and the equipment is properly checked.
At Petrolift, we believe every lift tells a story of discipline, teamwork, and responsibility.
Safety begins with you — and continues with knowledge.
