MecaLug Software

MecaLug is a Padeye or Lifting Lug Calculation Software package that is used to perform padeye or lifting lug calculations as well as analyze loads acting on padeyes or lifting lugs for a structure or piece of equipment.  Several different styles of padeyes or lifting lugs are offered giving the user multiple options in selecting an appropriate lifting lug.  There are also several different configurations in the MecLug Software for different equipment and structures.  The lifting lug software even has templates for lifting a stack or cylindrical vessel from horizontal to vertical, using either lifting lugs or lifting trunnions.  For this special type of lifting of stacks, the lifting lug software considers the multiple angles as the structure rotates from horizontal to vertical in order to find the worst angle on the lifting lugs/trunnions and tailing lug. is a Padeye or Lifting Lug Calculation Software package that is used to perform padeye or lifting lug  calculations as well as analyze loads acting 

Both the Standard and Pro version of MecaLug will allow the user to perform lifting lug calculations for a single Padeye / lifting lug. There are a variety of different Padeye / lug configurations that can be chosen to suit the specific needs. There are countless different lifting lug configurations used by companies, and so it is not feasible to include every possibility. 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. MecaLug adopts the use of ring analysis as well as local stress per WRC 537 (also known as WRC 107) to calculate the local stresses on the cylindrical shell.   This is especially important when analyzing lifting trunnions on cylindrical shells (shown to left), such as stacks or vessels, so that the local stress of the trunnion acting on the shell is considered.

As the data for the lifting lug or system is entered, a 3-dimensional representation is shown on the screen based upon the user entered parameters. This gives a quick check of all values entered to make sure they look correct.
