Swivel Hoist Ring Usage

Do not shock load swivel hoist rings.
When using a swivel hoist ring in a threaded hole the thread engagement must be at least 1-1/2 times the diameter of the bolt for steel.
When using a swivel hoist ring in a through-hole application a nut and washer must be used. Ensure the nut and washer meets the swivel hoist ring manufacturers specifications. Ensure the nut, when used, is fully engaged.
Do not use a swivel hoist ring unless the busing is in full contact with the surface of the load.
Do not use spacers or washers between the swivel hoist ring flange and the surface of the load being lifted.
Ensure swivel hoist rings are torqued to manufacturer's specs.
Ensure swivel hoist rings are in good working condition and all parts swivel and rotate freely.
Do not use or apply any component to the eye of a swivel hoist ring that is larger than the inside width of the swivel hoist ring bail.
Angular loads increase tension. Ensure any swivel hoist ring used has a suitable working load limit for the forces imposed.
