Structure advantages of tower crane hoisting booms

Hoisting jibs of building tower cranes can be classified to luffing jibs and horizontal jibs tower cranes. Luffing tower cranes depends on lifting up and down booms to realize radius changing. Its advantage is that can apply effective height of jibs fully, and mechanisms of tower cranes are simple.

Horizontal jibs tower cranes mainly relies on trolleying cars installed on jibs to realize radius changing. Its advantages are: radius range is wide, trolleying cars can be more close to tower crane body, and can load amplitude.
