Failure to do so may allow the coil rod to bend and precipitate a premature failure. WARNING: Eye Bolts are intended for straight tension loading only. Angular loading severely reduces the safe workloads and must be avoided or properly considered. See reduction factors below. Performance Data Print Product Email Product Inquire About this Product

failure of Crane. There are two main methods to classify an eyebolt. Specifications LIFTING EYE BOLT-TRAPEZIODAL SECTION . ISSN: 2277-3754 ISO 9001: Certified International Journal of Engineering and Innovative Technology (IJEIT) Volume 10, Issue 3, September

If recommended guidelines are not followed, the failure of a lifting eye can result in loss of property, personal injury, or even death in extreme cases. Forged vs. bent wire

Internally Threaded Rod End Bolts with Partial Threads. Also known as swing bolts and eyebolts, these internally threaded rod end bolts have no moving parts. They're designed to make pivoting or hinge movements in applications that don't need to compensate for misalignment.

Oct 03,  · The first lift with the eye bolt and it pulled out and fell. The eye had threads a size too small and had been JB welded to make the thread fit. FOR SURE never get under a load, never know what could happen. Thanks for that info on safe use of Eye bolts I will remember that.

The bolts which are used with collars are suitable even for angular loads whereas those which do not have a shoulder are not suitable for angular loads. However, for heavy off-axis loads, an eye bolt with continuous eye and integral shoulder can be used. Be sure to restrict the axis angle to less than 45 degrees.

When installing tapped type eye bolts DIN 582, When installing stud type lifting eye bolts WN This means that the minimum failure load is.

Stainless steel lifting eyebolts are used where there is the potential of corrosion contamination or failure caused by corrosion.

If bolted (not welded) eyebolts are to be used where shock loading, twisting or vibrations may occur then it is possible and recommended to further secure the 

Create your own lifting eye by adding an eye nut to a stud or bolt. Hoist Rings. Hoist Rings— For Lifting. Designed for angular lifting, hoist rings resist stresses that would bend or break an eyebolt. They have a lifting ring that pivots 180

Bolts can fail by due to several reasons including (1) the bolt had not been sufficiently preloaded/tension during installation, (2) had lost its preload during service, (3) the applied cyclic loading had been excessive – far beyond the strength of the bolt and/or (4) the bolt had been understrength (quality issue/wrong grade).

Shoulder Eye Bolts Never Exceed Working Load Limits. Never use regular nut eye bolts for angular lifts. Always use shoulder nut eye bolts for angular lifts.

NB: Please ensure that the safety instructions have been fully read and understood before initial use of the RS bolt-on lifting point. Failure to do so may 

WARNING. • Load may slip or fall if proper eye bolt assembly and lifting procedures are not used. • A falling load can seriously injure or kill.

Eyebolts, one of the most commonly used items of lifting gear, have severe limitations in usage and a high level of accidents occur as the result of misuse. Eyebolts are used in a wide variety of applications to provide lifting points on loads. Sometimes the hole they are screwed into is there specifically for the eyebolt.

A major contractor reported an incident that had occurred in which a threaded eyebolt failed during an operation to lift a section of stonework 

inspected the lifting equipment and the lifting points. • This failure relates to the failure of the onshore third party inspection. company to 

Failure scenario(s). The design of the anchor did not specify the orientation or material standards of the eyebolt anchor.

Inspect and clean the eye bolt threads and the hole. Check for bends, cracks, or worn threads. Screw the eye bolt on all the way down and properly seat. Ensure
