Issues with lifting lugs on tower-type equipment
Thread Content
According to the HGT 21574 standard, the AX type lugs are used for tower-type equipment. If the thickness of the container shell does not meet the requirements, apart from adding thickened sections to the shell as specified in clause 9.4, is there any simpler and more cost-effective method?
I need professionals to give me some advice!
No other methods are known at the moment; waiting for experts to respond.
Because one-time lifting requires thickening certain sections of the cylinder at the tower’s lugs, which is somewhat counterproductive, isn’t it?
Refer to the appendix on lifting lug standards; use WRC107, which is related to the local stress of SW6 components
I’ve done the calculations, and it really doesn’t work. Besides increasing the wall thickness, are there any other temporary reinforcement methods?
Try increasing the length and width of the pad and recalculate
A friend suggested installing temporary steel pipe supports inside the container at positions corresponding to the lifting lugs. I’m not sure if this is feasible; also, is it necessary to conduct calculations, and if so, how?
Local thickening: a cylinder is fitted over the outside of the barrel
Use a detachable tooling lift, so there is no need to thicken the wall thickness of the cylinder
Could you provide some reference materials? Thank you!
