Grade-8 Eye Bolts offer up to 4 times higher lifting capacity in certain applications. The larger internal eye diameter offers a versatile alternative to 

A simple and conservative approach is to calculate the length of a single shear plane as: L sp = a where a = R − 0.5 D h, as shown in the figure above. If it is desired to account for a slightly longer shear plane, it is common practice to consider a 40 degree line extending from the center of the shear pin.

padeye design and calculation. Each lift point consists of a padeye which is welded to the structure and connected to the sling by a shackle. The lifting force acting on the padeye is caused by the weight of the structure and the equipment used. This lifting force is transferred to the sling by a shackle put through the padeye pinhole, creating

The RC of an eye bolt is determined from a straight, zero degree, lift. As DIAGRAM 2 refers, a significant reduction in capacity is experienced any time a lift 

Swivel Eye Bolt SEB - FE.SEB. The SEB lifting ring is a single swivel ring. Equipped with 2 pins that always guide it perfectly in the direction of the sling. It is specially designed for lifting, including rotating loads. It consists of a GRADUP steel ring that has a rotating range of 360°. SEB lifting rings have a safety factor of 4 and 5

Use eye bolts at a horizontal angle greater than 45°. Sling strength at 45° is 71% of vertical sling capacity. Eye bolt strength at 45° horizontal angle drops 

Resultant stress in an eye bolt = Direct stress+ Bending stress Where, F= Load acting on eye bolt A=Area of cross section M=maximum bending moment. Y=Distance between centroidal axis to neutral axis. I=Moment of inertia for different cross section A. STRESS CALCULATION FOR CIRCULAR CROSS

How to calculate eye bolt capacity? · 5 degrees 100% of working load limit · 15 degrees 80% of working load limit · 30 degrees 65% of working load 

You do not specify if the fastener is UNC or UNF nor do you specify the grade of the fastener. These are required to know the cross section area of the fastener and to know the strength of the steel. Then it's a shear calculation based on the tensile strength. Usually I use .75 as my shear strength factor. See machinery's handbook. Sep 26, 2

The required minimum thread engagement to achieve the full lifting rating with the eye bolt in your threaded hole is based upon the inverse
