Tower cranes, often referred to as tower machines or tower hoists, originated in Western Europe. These are rotating cranes with a boom mounted on the upper part of a tall tower body. They offer a large workspace and are mainly used for the vertical and horizontal transportation of materials in building construction, as well as the installation of building components. A tower crane is composed of three main parts: the metal structure, the working mechanism, and the electrical system. The metal structure includes the tower body, boom, and base. The working mechanism consists of four parts: hoisting, luffing, slewing, and traveling. The electrical system includes the motor, controller, distribution cabinet, connecting lines, signaling, and lighting devices.
