Load Case 2: Handling The cask is designed to be supported on the two pairs of the trunnions during theA Lifting lug is a plate with a hole in it. Load Case 1: Lifting The loaded cask is lifted using the two upper trunnions as shown in Figure 1. The following load cases have been addressed. That the trunnion design meets the applicable requirements of 10 CFR Part 71 (Reference 2).
While lifting this mechanical equipment, the lugs must be able to carry the complete weight of the equipment. For mechanical static equipment Fig. Using lifting lugs combined with the clevis pins, loads are transferred from one mechanical component to another. The hole is sized to fit a clevis pin.
Hence, the lifting lug design has to be accurate enough to avoid any failure.

EXAMPLE 1: A plate lug used to lift a skid. Find, read and cite all the research.left of the lug plate, it can actually be either way and the calculations are still valid. To calculate the size of a motor. Lifting lugs can be of various shapes as shown in Fig.PDF This paper outlines the method of calculating the necessary size of motor needed to drive a lift or an escalator.
In the following section, we will see the design methodology followed for lifting lug design using PV-Elite software. The basic design of a lifting lug consists of the following four parts. However, As such standards do not clearly address the local stress calculation steps, Finite Element Analysis is performed using various software like Ansys, PV-elite, etc.Lifting lug design is very critical and hence mostly done using FEA software. For producing a safe reliable design, This is the most widely used lifting lug design standard.
They are also used to work as clamped pipe shoes. Pipe clamps are widely used for supporting suspended pipes. Save my name and email in this browser for the next time I comment.

When activated with lift lugs, the lift points are taken as the lift lug locations by default. It provides bending moment, shear stress and bending stress diagrams as well as tabulated values at main vessel locations.Variations in local sectional properties along the length of the vessel are considered. The Codeware rigging analysis can be used with or without the lift lug option.
Rigging analysis is considered in the vessel design. Benefits of our lifting and rigging analysis include. Apply the actual pressure vessel cross sectional properties.

MecaLug Pro version offers the same features of the standard version of the lifting lug software of analyzing a single lug or trunnion, but MecaLug Pro also has the added benefit of being able to apply those lugs to a lifting system and analyze what loads would be seen by the crane, cable, and lugs.This Pro feature of the MecaLug allows the designer to consider lifting a piece of equipment or structure, and have the software determine the loads acting on each individual lug. Top 5 Anchor Drop FailuresThe failure of a lifting lug could very likely put human life in danger in the event of a failure. Something is wrong with your submission.

Resources Learn methods and guidelines for using stereolithography SLA 3D printed molds in the injection molding process to lower costs and lead time.
Astro van ac fuseThis is especially important when analyzing lifting trunnions on cylindrical shells shown to leftsuch as stacks or vessels, so that the local stress of the trunnion acting on the shell is considered. MecaLug adopts the use of ring analysis as well as local stress per WRC also known as WRC to calculate the local stresses on the cylindrical shell. We have focused on the most common types of lugs that are used in the industry and those have been included in the lifting lug software.In the case of lugs attached to cylindrical shells, the local stresses are a concern from the lug acting on the cylindrical shell.
The structures usually start in the horizontal position and then they are rotated 90 degrees to the vertical position. There are unique problems that occur when a stack, vessel, or tower is lifted.
