Long Shank Dynamo Eye Bolts Metric Thread

How to use a Dynamo Eyebolt? Dynamo eye bolts are commonly fitted to the casing of equipment such as electric motors. They are extremely limited in their use. The SWL is lower than that of the collar eye bolt for axial loading and they cannot be used for angular loading. Loading by even 5 degrees out of the axial causes undue stress on the screw thread and shank. Dynamo eye bolts must not be used for trunnion lifting.

In-service Inspection and Maintenance

Maintenance requirements are minimal. Keep eye bolts clean, protect from corrosion and protect threads from damage. Do not attempt to straighten bent eye bolts or re-cut threads.

Regularly inspect eye bolts and, in the event of the following defects, refer the eye bolt to a Competent Person for thorough examination: illegible markings; distortion; worn, or bent shanks and threads; incomplete or incorrectly formed threads; damaged eyes; nicks, gouges, cracks, corrosion or other defects.

In the UK, the Lifting Operations & Lifting Equipment Regulations (LOLER) make it clear that all shackles and eye bolts used for lifting purposes are lifting accessories. They should therefore be subject to a thorough examination by a competent person at least every six months. Regardless of the prevailing legislation, the Lifting Equipment Engineers Association (LEEA) strongly recommends that this policy is adopted by all those with responsibility for ensuring the safe condition of lifting equipment.
