132HC Mast Section Definition, parameters and safety measures of lifting height of tower crane
The lifting height of the tower crane, also known as the hook height, is the vertical distance from the concrete foundation surface (or the top surface of the traveling track) of the tower crane to the hook. For the trolley luffing tower crane, the maximum lifting height is immutable. For the luffing tower crane, the lifting height varies with different amplitude. When the minimum amplitude is, the lifting height can be tens of meters higher than the tower tip, so the luffing tower crane has advantages in lifting height.

The lifting height of tower crane includes two parameters

The first is the lifting height when the tower crane is installed at the free height
The second is the maximum lifting height when the tower crane is attached. The tower crane does not need to be attached when the free height is installed. Generally, the tower crane can reach 40 meters, which can meet the needs of buildings below small high-rise buildings.

In order to prevent the equipment from being damaged due to the over lifting of the tower crane hook, a height limiter is installed on each tower crane. When the hook rises to 1-2m away from the boom, the lifting power supply will be cut off automatically to prevent the hook from continuing to rise.
