A tower crane is a type of construction equipment used to lift and move heavy materials on building sites. It consists of a tall vertical mast, a horizontal jib, and a counterweight. The crane operates by using a pulley system, allowing it to reach great heights and extend its reach over large areas. Tower cranes are commonly seen in urban construction projects, such as skyscrapers and large commercial buildings. They are designed for stability and can withstand strong winds, making them essential for high-rise construction. Operators control the crane from a cab located at the top, ensuring precise movements and safety.
