Parts of a Tower Crane
Tower cranes enable the construction industry to make some wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes provide the means to raise and transport tools, building parts and supplies around a construction site. There are various components which assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machines.
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. Generally, the construction should be engineered and built well in order 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 sections determines the crane's height. Typically, a tower crane has a design which allows the mast to grow during construction by adding further sections as the building process goes on. This way the crane's height could be specified, making sure that it has adequate height to safely and efficiently carry out the needed work.
Slewing Unit/Top Climber
At the top of the mast is the slewing unit. It houses the motor and machinery that allows the crane to rotate. A top climber is the piece of machine that allows the mast to grow. The top climber sits just beneath 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 working arm of a tower crane. The boom is made up of individual steel parts 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 base that could extend the length of the boom. This trolley holds the hoisting mechanism.
