16.6 INFORMATION WHICH SHOULD BE EXCHANGED BETWEEN THE USER AND THE DESIGNER OR SUPPLIER

As flat woven webbing slings are frequently used for multi-purpose lifting applications, precise details of the load to be lifted and mode of use are not always available. In these circumstances, only a general specification can be given but should, as far as possible, include the following information:

  1. Type of sling required, i.e. single, two leg, etc.

  2. Details of soft eyes and eye protection OR if terminal fittings are required to be attached to the sewn webbing component, the type, e.g. choker eyeplates, etc.

  3. The gross weight and dimensions of the load to be lifted together with details of any permanently built in lifting points if known or alternatively, the maximum load to be lifted.

  4. The effective working length of the sling.

  5. The mode of use, i.e. whether the sling is to be used in choke hitch or basket hitch, etc. In the absence of other information, the manufacturer will assume straight pull.

  6. The environmental conditions, particularly if the temperature is outside the range of -40°C to +80°C, if there is any exposure to specific chemicals or liquids, if the sling will be exposed to strong sunlight for long periods.

  7. The conditions of loading, including:

    1. Whether the sling is likely to be subject to shock load.

    2. Whether the load is to be transported over areas involving high risk, e.g. work areas. (This should not be done if it can be avoided.)

    3. Whether the load itself is hazardous.

  8. If any protective sleeves are required, the number, length and type of sleeves to be fitted.

  9. If any moulded wear pads are to be fitted, the length, number and position.

  10. The material of the sewn webbing component.

  11. Material and grade of any terminal fittings.

  12. If any special treatment or finish is to be applied to the sewn webbing component.

  13. Any special instructions including any special marking requirements.
