What is tower crane and how it works?

A tower crane is a type of construction tower crane that is commonly used on large building projects to lift and move heavy materials and equipment. It is typically mounted on a tall tower or mast and has a long horizontal jib that extends out from the tower. The crane operator sits in a cab at the top of the tower and controls the movement of the crane using a series of levers and pedals. Tower cranes are capable of lifting very heavy loads and can reach great heights, making them essential for many large-scale construction projects.
