Parts of a Tower Crane
Some of the most remarkable structures around the world are built with cranes. The newer cranes are designed to be able to reach higher heights. Tower cranes provide the means to raise and move tools, building parts and materials all over a construction location. There are various parts that assemble a tower crane when they are put together. Putting a tower crane together utilizes various pieces of construction equipment.
Base
The base of a tower crane is normally made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This set-up gives the structure 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 machine. The mast is made of attached steel parts. The amount of parts determines the crane's height. Usually, 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 certain that it has enough height to carry out the needed work efficiently and safely.
Slewing Unit/Top Climber
Above the mast is the slewing unit. It houses the motor and machinery which enables the crane to rotate. A top climber is the piece of equipment that allows the mast to grow. The top climber is located just beneath the slewing unit. Hydraulic rams inside the top climber enable the slewing unit to be disconnected 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 individual steel parts that 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 can run the length of the boom. This particular trolley holds the hoisting mechanism.
