Since the large converter tilting device generally weighs more than 160 tons, its installation position is located at the end of the trunnion across the converter, and the gap between it and the trunnion is very small. During hoisting, it must be ensured to be horizontal. Due to its irregular structure, it is easy to cause imbalance and non-horizontal during hoisting, thereby affecting the subsequent installation of the converter and being inconvenient for workers to use.

[0004] In view of the above defects, the present inventor has finally obtained the present application after long-term research and practice. SUMMARY
