6. Types of Jib Cranes

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.
