Parts of a Tower Crane
Tower cranes allow the construction industry to build some incredible structures. These cranes have been designed to reach ever-increasing heights. Tower cranes provide the way to transport and raise supplies, tools and building parts around a construction site. There are various parts which assemble a tower crane when they are put together. Putting a tower crane together utilizes different pieces of construction machines.
Base
Usually, the base of a tower crane is made from a steel unit. The base is attached to a custom-designed concrete pad. This type of set-up gives the structure stability. Generally, the construction needs to be engineered and built well so as to operate at optimum safety.
Mast
The mast on the tower crane provides the equipment with its overall height. The mast is constructed out of individual steel parts which are connected together. The amount of sections determines the crane's height. Usually, a tower crane has a design that enables the mast to grow during construction by adding further sections as the building process continues. This way the height of the crane could be specified, making sure that it has sufficient height to carry out the needed work safely and efficiently.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the machines and the motor that allows the crane to rotate. A top climber is the piece of machine that allows the mast to grow. The top climber is located just beneath the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be detached from the mast by raising it higher.
Boom
The term "boom", refers to the working arm of a tower crane. The boom is made up of separate steel sections that are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the bottom which could extend the length of the boom. This trolley has the hoisting mechanism.
