Some overweight machines can use two masts to form a herringbone shape, moving the lifting object laterally, but the amplitude is small and the operation is very difficult. In the 15th century, Italy invented  Luffing jib Tower Cranes  to solve this problem. The crane has a sloping cantilever with a pulley on the top of the arm that can be lifted and rotated.

As a  10 T Top kit Tower Crane Wholesale , share with you. Lifting height is also called hook height, which is the vertical distance from the concrete foundation surface of the tower crane (or the top surface of the walking track) to the hook. For trolley cranes, the maximum lifting height is immutable. For pitch cranes, the lifting height varies with different amplitudes. At the minimum amplitude, the lifting height can be several dozens higher than the tower tip meters, so the tower crane with pitch amplitude has an advantage in lifting height. Top Kit Tower Crane Tower crane lifting height includes two parameters, one is the lifting height when the tower crane is installed at a free height, and the other is the maximum lifting height when the tower crane is attached.
