Load Limits

You must always understand the working load limit when performing an inspection of eyebolts. The working load limit represents the maximum load that lifting eye bolts can safely handle during lifting. Manufacturers determine this value based on a straight vertical lift.

If you use an eyebolt for an angular lift, the working load limit drops sharply. You should avoid angular lifts whenever possible. If you must lift at an angle, use a properly seated shoulder-pattern eyebolt and keep the angle below 45 degrees. Always apply loads in the plane of the eye, not at an angle.

  • Working load limits for eyebolts are based on vertical lifts.

  • Angular lifts reduce the working load limit significantly.

  • Never exceed a 45° pull during lifting.

  • Calculate each lift’s angle to ensure safety.

You protect your team and equipment by respecting these limits during every inspection of eyebolts in use.

Sling Angles

Sling angles play a critical role in safe lifting and rigging. As the angle between the sling and the vertical increases, both sling and eyebolt strength decrease. You must always check sling angles during inspection of eyebolts. The table below shows how the sling angle affects capacity:
