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 means to lift and transport tools, building parts and supplies around a construction site. There are several different parts that assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machines.
Base
Normally, the base of a tower crane is made from a steel unit. The base is connected to a concrete pad that is custom-designed. This type of set-up gives the structure stability. Generally, the construction must 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 separate steel parts which are attached together. The amount of parts determines the height of the crane. Normally, a tower crane has a design which allows the mast to grow during construction by adding more parts as the building process goes on. This way the crane's height could be specified, ensuring it has adequate height to efficiently and safely carry out the needed work.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machines that enables the crane to rotate. A top climber is the piece of machine which enables the mast to grow. The top climber sits 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 attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the bottom that could extend the length of the boom. This trolley holds the hoisting mechanism.
