Issues with lifting lugs on towers and containers
Thread Content
Let’s discuss whether the lifting lugs for the sections of large-scale equipment towers should be welded by the equipment manufacturer Is there any difference in welding on-site?
The equipment manufacturer should arrange for personnel to carry out welding on site; due to the constraints present at the site, different treatment methods need to be considered for various materials
It is generally welded at the manufacturing plant according to the user’s requirements; if welding is done on-site, attention should be paid to whether heat treatment is necessary.
It should be welded directly at the factory, and then lifted straight to the site
It is generally required to be welded at the manufacturing plant
Due to the large diameter of the equipment, which may affect its transportation, it is necessary to weld the lifting lugs on-site. Therefore, taking into account the requirements of the manufacturing process and the on-site conditions, it is essential to assign personnel to carry out this work on site. On-site welding also requires compliance with manufacturing specifications regarding the selection of welding materials, non-destructive testing such as coloring, and post-weld local heat treatment.
For large equipment, considering transportation issues, if there aren’t large enough vehicles available for transport, it’s necessary to assemble them on-site. All of this welding should be carried out by the manufacturer. If heat treatment is required, welding should be done first followed by heat treatment
Whether it is a sidewall plate lifting lug, an axle-type lifting lug, or a tail lift on a cluster seat. It has nothing to do with transportation, right? I heard about it for the first time when it came to welding on site! No matter where the welding is done, stress must still be checked
