Which feature distinguishes a tower crane from other types of cranes?

The distinguishing feature of a tower crane is its vertical standing lattice-frame central mast. This design allows the tower crane to reach great heights and provides stability and rigidity, which are essential for supporting heavy loads and working at significant elevations. The structure's height allows it to operate efficiently in congested urban settings, making it ideal for projects like high-rise buildings.

In contrast, other types of cranes may have different configurations, such as mobile cranes that utilize a less rigid frame and are designed for horizontal movement and mobility rather than vertical stability. Additionally, while some cranes feature horizontal booms or operating cabins, these characteristics are not exclusive to tower cranes and can be found in other types as well. The central mast’s vertical design is what truly sets tower cranes apart and enables their unique operational capabilities in construction.
