  • All markings are clearly legible.
  • The shackle pin is the correct type for the body.
  • The threads of the shackle pin and the body are in good order and function correctly.
  • All parts are examined ensuring that no parts are damaged in any way and are free from any dents, cracks, deformation etc.
  • All load rated shackles/blocks are supplied with a WLL and proof load test certificate in accordance with EN10204 3.1b. Each shackle/block is individually tested to its proof load (2 x WLL).


Each shackle/block is mechanically engraved with the following details

  • Working Load Limit (WLL).
  • Batch number specific to the test for that batch of product.
  • The grade of stainless steel which the product is manufactured from.
  • CE mark.

Instructions for use

Shackles/Block should be inspected before use to ensure that:

  • all markings are legible.
  • the threads of the shackle pin and the body are undamaged.
  • never use a safety type bolt/pin without using the split cotter pin.
  • the equipment is not distorted or unduly worn.
  • the equipment is free from nicks, gouges, cracks and corrosion.
  • shackles may not be heat treated as this may affect their working load limit.
  • never modify, repair or reshape a shackle or block as this will affect the Working Load Limit.



Inspection of the Petersen Lifting Shackles and Blocks

Before any piece of equipment is first put into use it should be examined for signs of damage.

If it is known, or suspected, that the equipment has been subjected to an excess load or it shows any sign of cracking, splitting or deformation it must be destroyed.

It is required that the equipment is regularly inspected and that the inspection should take place in accordance with the safety standards given in the country of use. This is required because the products in use may be affected by wear, misuse, overloading etc. with a consequence of deformation and alteration of the material structure. Inspection should take place at least every 6 months and even more frequently when the equipment is used in severe operating conditions.
