5 Rigging Mistakes Every Contractor Should Avoid

June 28, 2022

Rigging is essential to cranes as it can affect the whole operations once it is not done optimally. Rigging involves the use of ropes, pulleys, and other equipment in securing heavy loads to the cranes. It is often carried out by riggers, who have all the needed skills, knowledge, and other factors that make them qualified for the process.

Riggers are expected to carry out rigging operations without any issues. However, if the necessary rigging methods are not followed or carried out, it could affect the stability of the load while it is in the air. Overlooking some areas of the rigging process can also lead to safety risks among workers.

Tons of rigging mistakes should be avoided by contractors, especially those who will be performing the rigging process. Some of them are as follows.

1. Neglecting Rigging Charts

One mistake that every contractor should avoid is neglecting the rigging charts. Rigging charts are comprised of crucial values that must be observed to ensure a successful rigging. Riggers who fail to consider the sling hitches and angles will only compromise the rigging process. The whole rigging process may likewise fail if the rigger does not account for the changing capacities of slings, especially when adjusting the angles or maximising a different hitch.

2. Disregarding Load Weight

Another crucial rigging mistake that every contractor should not do is disregarding the weight of the load. A lot of riggers have been in the industry for years. And so, some of them end up estimating the load weight instead of determining its true value. Doing this can be extremely risky since the crane might not be able to handle the weight of the load. To determine the load weight, riggers may utilise an industrial scale, refer to engineered prints or design plans, or calculate the weight themselves.

3. Discounting Sling Capacity

Somehow similar to the weight of the load, riggers should also avoid discounting the capacity of slings and other hardware. Some slings and other hardware may not have their tags anymore. And since their capacity cannot be determined right away, they are expected to be removed immediately from service. Failure to remove these things will only lead to crane failures during their operations. 

4. Skipping Vital Inspections

Equipment pieces and devices should always be inspected and assessed by contractors to ensure that they can operate optimally. If these activities are not conducted by contractors to the rigging equipment, they may end up failing during the lifting operations. They may even affect the overall site processes. Damages, defects, and deformities are only some of the potential signs of deteriorated gears. Detecting these issues as early as possible can help make rigging operations successful.

5. Using Low-Quality Devices

One more rigging mistake that contractors should avoid is utilising low-quality below-the-hook devices and modified equipment pieces. Makeshift, modified, and homemade devices should always be prevented from rigging processes since their working load limit cannot be measured accurately without proper load testing. Utilising these things will only pose some safety risks to the whole rigging setup.
