Misconceptions

Misconseption 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.

Alloy Steel Chain slings are greatly effected in these situation, wrapping a chain around a 90 degree corner applies point loading on the links and can cause damage or failure of the chain, also using the chain around a small radius will reduce the capacity the sling can lift.

The minimum radius or D/d ratio recommended by the manufacturer must be known before using the sling in these situations.
