20.10.3 Attaching the Lifting Accessory

Collar eyebolts without links need a shackle for connection to a hook.

If a single eyebolt is used for lifting a load which is liable to revolve or twist, a swivel or swivel type hook should be used to prevent the eyebolt unscrewing.

Where two eyebolts of the same capacity are used in conjunction with a two leg sling, the eyebolts should be rated to the appropriate maximum working load tables given in the manufacturer’s instructions for use. Use the longest legs possible to minimise the angle to the vertical and thus the angular loading on the eyebolts. If practicable, a lifting beam or spreader should be used to obtain full SWL of the eyebolt in axial lift. Dynamo eyebolts are intended for axial lifting only; if used in pairs a lifting beam MUST be used.

Ensure that eyebolts are not overloaded due to the method of slinging, especially when used in pairs. The correct and incorrect methods of slinging using a pair of eyebolts are shown in Figure 20.10.3-1 . A sling should not be reeved through the eyebolts or shackles as by this method the loading in the eyebolt is considerably increased.

If these requirements cannot be met or for more complex lifts using three or more eyebolts, a Competent Person must be consulted.
