Flattop tower cranes have special connection methods, no tower head and pulling rod, that make it's easy and safe to mantle and dismantle hoisting jib in the air, if need to add or reduce the length of hoisting jib, don't need to dismantle the whole jib, can be finished in the air. At hyperbola ooling tower construction site, usually needs to change range. After finishing of builiding, have to pass min. Bore diameter, usually have to dismantle some jibs, sometimes most of jibs that can let tower crane descend. Because topkit tower cranes will be restricted by pulling rod, only can dismantle jibs outside hook point, it's difficult to dismantle pulling rod, flattop tower cranes can do that.
