lifting eye bolt failure

Dec 17,  · An eye bolt is to be used for lifting a load of 30 kN. Find the nominal diameter of the bolt, if the tensile stress is not to exceed 100 MPa. Assume coarse threads from the below tables. 2. Four eye bolts are to be used for lifting a load of 280 kN. Find the nominal diameter of the bolts, if the tensile stress is not to exceed 100 MPa.

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).

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.

391 products. Eye bolts have a shank for anchoring to structures or equipment and a ring (or loop) at the top for attaching rope, hooks, or other hardware. They're used as anchor eye bolts for routing or tying down wire and cable. Machinery or lifting eye bolts are rated for vertical or angular lifting up to their specified capacity. Application.

Therefore, in order to minimize the possibility of a brittle cleavage failure, these lifting eyes should never be loaded above the proof load, and should not be used when surface discontinuities exist on the lifting eyes. Eyebolts manufactured in accordance with ASTM A489 should only be used at temperatures between 32 °F and 275 °F.

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

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

Closed end forged eye bolts with a shoulder are the only eye bolts that are load rated. They must be mounted against a flat surface or washer to 

When lifting machinery, it is common for an eyebolt to be screwed directly into a tapped hole in the structure. In this case, an eyebolt is 

FAILURE OF LIFTING EYEBOLT RESULTS IN DROPPED OBJECT. WHAT HAPPENED: The deck crew was attempting to move an electric motor weighing approximately 200kg 

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

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

A mistake common among untrained riggers is the use of a shackle capable of lifting more than the eye bolt to which it's attached. If, for
