Parts of a Tower Crane
Some of the most remarkable structures throughout the world are made using cranes. The newer cranes are utilized to be able to reach higher heights. Tower cranes provide the means to move and lift building parts, materials and tools all over a construction location. There are various parts which assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction machines.
Base
Usually, the tower crane base is made from a steel unit. The base is attached to a custom-designed concrete pad. This set-up gives the structure stability. Generally, the construction must be well engineered and built in order to operate at optimum safety.
Mast
The mast on the tower crane provides the machinery with its overall height. The mast is built out of individual steel parts that are attached together. The amount of sections determines the height of the crane. Normally, a tower crane has a design that allows the mast to grow during construction by adding further parts as the building process goes on. This way the crane's height could be specified, ensuring it has enough height to perform the required work safely and efficiently.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the equipment and the motor that enables the crane to rotate. A top climber is the piece of machinery which allows the mast to grow. The top climber is located just underneath the slewing unit. Hydraulic rams inside the top climber enable 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 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 particular trolley has the hoisting device.
