Threaded socket head bolt. Stainless steel, European Standard No. 1.4462. GN 581.5 swivel lifting eye bolts offer a high load carrying capacity and are tested 

The required minimum thread engagement to achieve the full lifting rating with the eye bolt in your threaded hole is based upon the inverse ratio of your material's strength to the fasteners' material. i.e Lmin hole = Lmin Nut X Bolt material strength / Threaded material strength.

At All Lifting we offer an extensive, durable range of eye bolts, eye nuts, lifting lugs and swivel rings. Each eye bolt or eye nut is rated for different types of applications. We can also custom manufacture almost any thread length, working load and thread type. Find out more and choose from an extensive range available at All Lifting today.

6/24 · Practices to avoid when using lifting eye bolts: Running a Sling Through Eye Bolts. It's often convenient to run a sling through a pair of eye bolts, however, it should be avoided.

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

There are two main methods to classify an eyebolt. Specifications. Specifications for eyebolts include: • Maximum capacity for loading – The 

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 

1. 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.

These lifting eye bolts correspond to standard sheet DIN 580. The following guidelines of lifting eye bolts DIN 580 the have to be observed in addition to the load values given in the above table. The eye bolt must be of fully screwd in to achieve a perfect contact between the two mating faces.

Intended for straight line pulls only. For angled pulls, choose a Shoulder Eye Bolt. California Residents: WARNING. Show Less. The aim to lift a 7.55 ton load using the lift plate (with pad eye) as shown in the pic below. Following are the stresses that i am able to calculate, 1) double plane shear due to shackle pin at pad eye hole.

These lifting eye bolts correspond to standard sheet DIN 580. The following guidelines of lifting eye bolts DIN 580 the have to be observed in addition to the load values given in the above table. The eye bolt must be of fully screwd in to achieve a perfect contact between the two mating faces. Both threads must be of a equal length and the

The capacity specified in the table (F2 and F3) applies up to an inclination angle of 45°. You will find further information in DIN 580:2010-09, 

This definitive guide has been compiled for buyers and users in the selection of lifting eye bolts and lifting points.

The padeye calculator is based upon the following calculation procedure: 1) Enter design load including factors ( F) 2) Select a shackle size from the 'SWL' list 3) Enter cheek-plate and pin-hole clearances ( C & Cᴾ) 4) Enter a maximum allowable stress for the padeye plate ( σ)

At 15 degrees, the working load limit is reduced by 20% and the effective working load limit of the eye bolt becomes 1240 pounds, which is 80% 

Eye Bolt Type Fixed Shoulder Type Without Shoulder Thread Size 5/8-11 Lifting Capacity 3500.0 Shank Length (Inch) 8 Lifting Capacity (Lb.) 3500.00 Thread Style 

Always apply load to eye bolt in the plane of the eye. Quenched & Tempered • Design Factor 5/1 Swivel Hoist Rings When using lifting slings of two or more legs make sure the forces in the leg are calculated. Select the proper size swivel hoist ring to allow for load in sling leg. Always insure hoist ring is free to align itself with sling.

3/27 · The aim to lift a 7.55 ton load using the lift plate (with pad eye) as shown in the pic below. Following are the stresses that i am able to calculate, 1) double plane shear due to shackle pin at pad eye hole. 2) bearing stress for the pad eye hole / pin interface. 3) 8 X bolt stresses due to hanging weight.

diameter of the thread (1-1/2 times bolt diameter - steel). Sample Calculation: Jergens swivelling hoist rings are designed and rated to be pulled at any angle at the rated load. However, the applied load on a multipoint lift will increase if the sling angle is less than 90°. So be sure to consider the sling angle when selecting lifting

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 multiplier factor can be calculated as follow : C e = 1 cos ⁡ ( 0. 5 ⋅ α) C {e} = \frac {\displaystyle 1} {\displaystyle \cos (0.5 \cdot \alpha)} C e = cos(0.5⋅α)1. . With α the angle formed between : the two slings connecting the most distant points if no specific balancing system is used. the two slings connecting points side by

The applied load (F) for lifting appliances can be determined by any suitable calculation facility including CalQlata 's lift rigging calculator. It is important, however, that appropriate factors (DAF, SF) are applied to any design load. Eye bolt lifting capacity calculation. ri snap recertification online.

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 

Lifting eye bolts must be marked permanently raised with manufacturer's mark, material ID (e.g. C15E, A2 or A4), load-bearing capacity and 

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.
