  2. Each new shackle pin must be marked by manufacturer to show name or trademark of manufacturer and grade, material type or load rating.
  3. Shackles must be inspected visually by the user (or other designated person) prior to each use and periodically.
  4. Repairs and/or modifications may only be as specified by the manufacturer. Replacement parts, like pins, must meet or exceed the original manufacturer's specifications.
  5. Shackles must not be eccentrically (side) loaded or shock loaded.
  6. Multiple sling legs must not be applied to the shackle pin.

  1. All hooks used for lifting or load handling purposes must not be used in any other manner.
  2. Hooks that show wear exceeding 10% or an increase in the throat opening of 5% (maximum of 1/4 in (6mm)), or as recommended by the manufacturer, or any visibly apparent bend or twist from the plane of the hook must be removed from service.
  1. The manufacturer's recommendations must be followed in determining the WLL of the various sizes and types of specific and identifiable hooks.
  2. Any hook for which the manufacturer's recommendations are not available must be tested to twice the intended safe working load before it is put into use.
  3. The employer must maintain a record of the dates and results of such tests.
Figure 15-4
Figure 15-4
  1. Open hooks are prohibited in rigging used to hoist loads except for miscellaneous- type hooks (i.e., grab hooks, foundry hooks, sorting hooks, choker hooks, etc). These hooks may be used as long as they are inspected and maintained in accordance with manufacturer's recommendations. The use of these specialty-type hooks must be identified in the applicable AHA and submitted to the GDA for acceptance. > See Figure 15-4.
  2. Manufacturer's identification (country only is not acceptable) and WLL must be forged, cast, or die stamped on a low stress and non-wearing area of the hook.
  3. Duplex (sister) hooks must be loaded equally on both sides unless the hook is specifically designed for single-point loading.
  4. If the duplex (sister) hook is loaded at the pinhole instead of at the two saddles, the load applied must not exceed the WLL that would normally be shared by the two saddles or the WLL of the supporting equipment.
