Parts of a Tower Crane
Several of the most remarkable structures around the world are made using cranes. The newer cranes are utilized in order to reach higher heights. Tower cranes provide the way to lift and move tools, building parts and materials around a construction site. There are various parts that assemble a tower crane once they are put together. Putting a tower crane together uses different pieces of construction machinery.
Base
The tower crane base is usually made from a steel unit. The base of the unit connects to a custom pad made of concrete. This kind of set-up gives the structure stability. Generally, the construction must be engineered and constructed well so as to operate at optimum safety.
Mast
The tower cranes mast provides height to the equipment. The mast is made of attached steel parts. The amount of sections determines the crane's height. Usually, a tower crane has a design which enables the mast to grow during construction by adding more parts as the building process goes on. This way the crane's height can be specified, ensuring it has enough height to safely and efficiently carry out the required work.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the machines and the motor which allows the crane to rotate. A top climber is the piece of machine which enables the mast to grow. The top climber sits just below the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be disconnected 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 underside which can run the length of the boom. This trolley holds the hoisting device.
