A quick visual inspection, then start your lift. Other alloys available upon request. Serving the welding and fabrication community with over 100 years of combined experience Using our 100+ years of combined experience, we have invented and constantly improved several lines of forged metal products for the fabrication and welding industries since 1999. This has given us great insight on exactly what is needed to create a selection of engineered padeyes. We constantly strive to make life easier for our clients by providing unique solutions to save time and cost on projects. With the introduction of the world's first engineered and certified padeyes, we have taken care of several steps so you can simply weld them on and be assured of the lifting capacity and safety without having to go through testing and certification yourself. Being the first and only company to offer engineered/certified padeyes, we are sticking to a stringent quality assurance and control protocol to offer world class products you can rely on.

My problem is: how does one find the von Mises equivalent stress in a simple hand calculation (without using FEA)? Neither principal stresses are known, nor any local tensile and shear stress components.
The padeyes and lift points geometry will be designed to exactly match the standard shackles rated to what the various standards specify. The shackles will typically be standard Green Pin bow shackles with safety bolts. The load direction on the pad eyes are normally 30 degrees angle from vertical, but custom pad eyes can be designed and analysed for any angle if required. The welds to the ground material shall be full penetration welds and the quality of the ground plate with tensile stress must be Z-quality. The padeyes and lifting points must also be designed for the lateral load as defined in the design code. The lateral side load is ranging from 3 to 20 degrees based on the code and design class chosen.

A padeye is a device often found on boats that a line runs through, or provides an attachment point. It is a kind of fairlead and often is bolted or welded to the deck or hull of a boat. It is also used in oil and gas projects to assist in the purpose of lifting. It's made of steel plate with radius at oneside. lifting is done with the help of D-shackle or sling, which fits into the hole of padeye. there may be one or more circular plates(cheek plates) welded around the hole. The following checks should be done for the designing of padeyes and keep the stress less than the allowable stresses At the hole: 1. Bearing stress 2. Shear stress 3. Tensile stress 4. Hertz Bearing stress At the base 1. shear stress 2. Tensile stress 3. Bending stress 4. Combined bending stress and tensile stress 5.
