Tower cranes are essential for constructing tall structures, with varying types differing in boom configuration and operational capabilities. The erection and dismantling processes, particularly with climbing cages, enhance efficiency and minimize the need for additional cranes. Key factors affecting lifting capacity include boom geometry and the operational radius, emphasizing the importance of stability to prevent accidents.

Articulated jib cranes can convert horizontal reach into vertical height by adjusting the hinged jib.
The erection of tower cranes can be performed using climbing cages, reducing the need for an additional mobile crane after the initial setup.
The maximum free-standing height for tower cranes generally ranges from 60 to 120 meters without structural support.
A type of crane boom capable of changing its angle to adjust the height and reach of the crane.
A mechanism that enables self-erection of a tower crane by allowing it to add new sections without external assistance.
The horizontal distance from the center of the crane's rotation to the hook, influencing the crane's stability and lifting capacity.
The load that will cause the crane to tip over, which must not be exceeded for safety.
The point at which the weight of a load is balanced, crucial for stable rigging.
