Generally, tower-type systems are the most expensive, self-supporting types are next in cost, while cable-driven types are the least expensive； The pull rope requires the most space, and can be selected based on the specific conditions on site. Self-acting structures are greatly affected by natural conditions; in simple terms, they are tower-like structures that are significantly influenced by the strength of the ground and natural conditions. It’s just my understanding; for reference only.
My personal understanding is: structures over 80m should use tower types, those between 50-80m can use self-supporting types, and those under 50m should use rope-pulled types
