Parts of a Tower Crane
Tower cranes allow the construction industry to make various wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the way to raise and move tools, building parts and materials all over a construction site. There are a few different parts that assemble a tower crane when they are put together. Putting a tower crane together uses various pieces of construction equipment.
Base
The tower crane base is usually made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This set-up gives the structure stability. Generally, the construction must be engineered and built well in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machine. The mast is made of attached steel parts. The amount of sections determines the crane's height. Typically, a tower crane has a design that enables the mast to grow during construction by adding more parts as the building process goes on. This way the height of the crane could be specified, making sure that it has enough height to safely and efficiently perform the required work.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machines that allows the crane to rotate. A top climber is the piece of equipment which allows the mast to grow. The top climber sits just below the slewing unit. Hydraulic rams inside the top climber allow the slewing unit to be detached from the mast by raising it higher.
Boom
The term "boom", refers to the tower crane's working arm. The boom is made up of individual steel parts which are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the base which can run the length of the boom. This particular trolley holds the hoisting mechanism.
