Parts of a Tower Crane
Some of the most wonderful structures around the world are built utilizing cranes. The newer cranes are utilized in order to reach higher heights. Tower cranes provide the way to transport and lift supplies, tools and building parts around a construction site. There are various parts which assemble a tower crane once they are put together. Putting a tower crane together uses various pieces of construction machinery.
Base
Typically, the base of a tower crane is made from a steel unit. The base is attached to a concrete pad that is custom-designed. This set-up provides the structure with stability. Overall, the construction should 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 sections. The amount of parts determines the height of the crane. Usually, a tower crane has a design which enables the mast to grow during construction by adding further parts as the building process goes on. This way the height of the crane can be specified, ensuring it has adequate height to perform the needed work safely and efficiently.
Slewing Unit/Top Climber
At the top of the mast is the slewing unit. It houses the motor and equipment which enables the crane to rotate. A top climber is the piece of machinery which enables the mast to grow. The top climber is situated 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 separate steel sections which are attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the base that can extend the length of the boom. This trolley has the hoisting mechanism.
