Collar eye bolt

Alignment of the eye is also very important. Collared eye bolts can be used up to the marked SWL provided that the load is in line with the axis of the eye bolt. Collar eye bolts may also be used for non-axial loading provided that the SWL is reduced by the appropriate factors. The load should be applied within + or - 5º of the plane of the eye. The collar eye bolt is not suitable for direct connection to a hook; a shackle is usually employed for this.

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.
