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.

Wire Rope slings are greatly effected in these situation, wrapping a wire rope around a 90 degree corner applies point loading to the wires and can cause damage or failure of the rope, also using the wire rope 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. Any size object can be used in the eye of a Wire Rope Sling where no thimble is present.

An object in the eye of the Wire Rope sling should not be wider than 1/2 the length ot the eye nor less than the nominal slng diameter.
