No other solution: a Φ4000, H40000 double-phase steel tower weighing 50 tons without lifting lugs – the so-called bundled lifting method

No other solution: a so-called bundled lifting scheme for a Φ4000, H40000, 50t tower made of double-phase steel without lifting lugs. Additionally, the tower is already equipped with various pre-welded components. The design office stated that it was designed without lugs, and simply said that binding lifting should be used; as for the specific method of binding, what size of protective washers or blocking wood are needed, and what specifications such blocking wood should have. . . . Didn’t say. The construction company is rather rough. . . Experts, how should we deal with this approach? ? Give some advice. I think design institutes are kind of funny.
http://www.doc88.com/p-114617833879.html Take a look at this; it also features a tower crane, and it’s even heavier than yours! SM lifting method: lol
After reviewing the details, it can be seen that the equipment does have lifting lugs; however, there is no tail lift – instead, the tail section is lifted using binding methods. This preliminary plan is intended to serve as a guide for selecting the crane, lifting lugs, and ropes, and it is not a detailed design. Although this equipment is much heavier than ours, there are still significant differences in terms of its characteristics. The tail section is actually easy to solve. Anyway, thank you. . . .
I searched through quite a lot of information; for the majority of vertical components (equipment, towers), slinging is rarely used for lifting. According to chemical industry standards, horizontal equipment is lifted using sling methods, while vertical equipment can be lifted in two ways: either by using sleepers for slinging or by installing hoop-type lifting lugs. It has not been found yet whether any actual engineering projects have adopted this approach; urgent guidance from those with experience is needed.
