The house beam C-shaped steel is hung from the hook

2016-07-12View Original

Thread Content

To build a small factory building, C-shaped steel members are lifted using a crane and welded to the columns; this is not allowed according to the regulations. Is there any good construction method for this? Thank you!

C-shaped steel, channel steel? Tie a rope at the symmetrical position of the C-shaped steel, then hang it from the middle of the rope to form an isosceles triangle; can we also tie a sliding rope?

Code for Safety Technology in Construction of Petrochemical Projects 3.6.6 Welding or cutting operations shall not be carried out on workpieces and equipment suspended from the crane hook. I’m not sure what to do.

Could you explain the reason? In actual work, there are many cases where lifting is used for welding/cutting tasks.
