Revolving wheel replacement

Top-mounted replacement

Condition: There is ample space at the top of the rotor, and there are no obstructions above. 

Advantages: The working space is spacious, and the construction efficiency is the highest; the overall lifting is carried out without disassembling the modules. 

Disadvantages: It relies on the top lifting space and lifting equipment. 

Construction period: ★★★★ Shortest 

The fastest and simplest solution. 

Side-out replacement

Condition: The top space of the rotor is insufficient or there are pipes/bridges above, but there is an operating space on the side. 

Advantages: It does not rely on the top space; the operation on the side is also reliable; the dedicated tooling is combined, and the construction is standardized. 

Disadvantages: It requires sufficient space on the side for installation; the process is slightly more complex than top-lifting. 

Construction period: ★★★☆☆ Medium 

Flexible and adaptable solution

1/8 module replacement

Condition: The top and side spaces of the rotor are both limited, and it is impossible to lift or push out the entire rotor. 

Advantages: It adapts to the narrowest installation space; the modular replacement is carried out one by one, and each module is lightweight and flexible to operate. 

Disadvantages: There are many modules (8 pieces), and the process is more complex; the construction accuracy is high, and each module needs to be precisely adjusted and positioned. 

Construction period: ★☆☆☆ Long 

Space-restricted solution
