Slinging Safety

The correct use of chain slings results in safety for all employees and economical sling life.

Safe Slinging
Unsafe slinging poses risks,not only to the load and anything in its path if it fails, but also to the crane or lifting machine and the structure from which it is suspended. The sudden release of a load can result in a catastrophic chain of events resulting in loss of life ore serious injury and damage to property. (This means You and Your property)


It is important that all users of lifting tackle be trained in the correct and safe use of lifting tackle. To avoid the possibility of sling failures due to improper handling we offer the following suggestions:

Causes of lifting accidents:

  • Lack of knowledge, training and supervision
  • Abuse of equipment
  • Incorrect use or choice of equipment
  • Failure to establish the mass of the load
  • Failure to establish the stability of the load
  • Failure to inspect equipment for damage before use
  • Failure to conduct statutory inspections and maintenance
  • Using untested or home-made lifting tackle
  • Failure to consult rigging charts, i.e. - important of angles, choker hitches, etc.

Extracts of the OHS Act No. 85 of 1993

Driven Machinery Regulations 2015 Act 18 Sub 10

No user may use or allow the use of any lifting tackle unless –

  1. every item of lifting tackle is well constructed of sound material, is strong enough, is free from defects and is constructed in accordance with a generally accepted technical standard
  2. every lifting assembly consisting of different items of lifting tackle is conspicuously and clearly marked with traceable identification particulars and the safe working load that it is designed to lift with safety.
  3. the ropes, chains or woven webbing have a factor of safety with respect to the safe working load they are designed to lift; the safety factor being

  • 10 for natural -fibre ropes;
  • seven for man -made fibre ropes or woven webbing;
  • six for steel -wire ropes, except for double -part spliced endless sling legs and double -part endless grommet sling legs made from steel -wire rope, in which case the factor of safety shall be at least eight;
  • five for steel chains; and
  • four for high -tensile or alloy steel chains:

provided that when the load is equally shared by two or more ropes or chains the factor of safety may be calculated in accordance with the sum of the breaking strengths taking into consideration the angle of loading;
