Parts of a Tower Crane
Tower cranes allow the construction industry to build various incredible structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the way to transport and raise tools, building parts and supplies all around a construction site. There are several different components which assemble a tower crane once they are put together. Putting a tower crane together utilizes different 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 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 sections. The amount of parts determines the height of the crane. Typically, a tower crane has a design that allows the mast to grow during construction by adding more sections as the building process goes on. 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 situated above the mast. This unit houses the machinery and the motor which enables the crane to rotate. A top climber is the piece of machine which enables 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 disconnected 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 individual steel sections which are attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the base which could run the length of the boom. This trolley has the hoisting mechanism.
