12.9.1 Marking

In addition to the requirements of the applicable national legislation the following information should be permanently and legibly marked on a suitable part or parts of the mobile supporting structures:

  1. Identification mark(s). (If the manufacturer has not provided a unique serial number then it is the responsibility of the user to add the identification mark to identify the equipment with the inspection and examination reports)

  2. SWL. This should be marked on both sides of the mobile supporting structures in such a way that it is readily legible from the operating position.

  3. Name of manufacturer or supplier.

  4. Year of manufacture.

  5. Maximum hoisting speed for powered hoists or else the words ‘Manual Hoist’, where different hoist could be fitted.

In addition, it is advisable that the weight of the structure is marked or otherwise made readily available.

Special care must be taken with regard to the SWL of the mobile mobile supporting structures and lifting appliance(s). The maximum load to be lifted, including the weight of the equipment, should not exceed the marked SWL of the mobile supporting structures. This is particularly important in cases where the lifting appliance is regularly removed and replaced as may be the case with self-erecting or foldaway mobile supporting structures, or where more than one lifting appliance is being used, i.e. multi-point lifting.
