Misconceptions

Misconception 1. If you have attended a training course you are a competent rigger.

Training is only one part of being competent to carry out your job, you must also be adequately qualified and have sufficient experience.

Read Details

Misconception 2. A slings capacity stays the same when used around an edge or corner.

Synthetic Webbing slings are greatly effected in these situation, wrapping a webbing sling around a 90 degree corner applies point loading to the fibres and can cause damage or failure of the webbing, also using the Synthetic Webbing Sling around a small radius will reduce the capacity the sling can lift. 

Read Details

Misconception 3. Synthetic Webbing Slings are not affected by water.

Water absorption can decrease the strength of Nylon Synthetic Webbing Slings by as much as 10-15% (its strength returns when the sling dries completely)

Read Details

Misconception 4. Any size object can be used in the eye of a Synthetic Webbing Sling.

An object in the eye of a Synthetic Webbing Sling should not be wider than 1/3 the length of the eye. 

Read Details

Misconception 5. Synthetic Webbing Slings can be cleaned by washing.

Do not wash slings, as loss of strength is possible due to mechanical or chemical damage.
