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.

Polyester Roundslings are greatly affected in these situation, wrapping a sling around a 90 degree corner applies point loading to the internal fibres and can cause damage or failure of the sling, also using the Polyester Roundslings 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.  

Read Details

Misconception 3. When attaching Polyester Roundslings to a load using shackles or other connecting means, the diameter used within the sling does not matter as long as the capacites are equal to the slings rating.

Polyseter Roundsling strength is affected by the size/diameter of the connection hardware. The manufacturer of relevant standards must be referenced to assess the minimum diameter allowed for the capacity of the sling used 

 

Read Details

Misconception 4. Polyester Roundslings can be wrapped around chamfered corners.

Polyester Roundslings shall not be allowed to come into contact with edges that are chamfered, or flattened at an angle, unless the edges conform to edge radius requirements.
