Parts of a Tower Crane
Some of the most wonderful structures around the world are made using cranes. The newer cranes are used in order to reach higher heights. Tower cranes offer the means to raise and move tools, building parts and materials all over a construction location. There are a few different parts that assemble a tower crane once they are put together. Putting a tower crane together utilizes different pieces of construction machines.
Base
The base of a tower crane is normally made from a steel unit. The units' base connects to a custom pad made of concrete. This set-up gives the structure stability. Overall, the construction needs to be engineered and built well so as to operate at optimum safety.
Mast
The tower crane's mast provides the machine with its overall height. The mast is constructed out of individual steel parts which are connected together. The amount of parts determines the crane's height. Usually, a tower crane has a design that allows the mast to grow during construction by adding further parts as the building process continues. This way the crane's height could be specified, ensuring it has enough height to efficiently and safely perform the needed work.
Slewing Unit/Top Climber
At the top of 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 machinery that allows the mast to grow. The top climber is located just underneath the slewing unit. Hydraulic rams in the top climber enable the slewing unit to be detached from the mast by raising it higher.
Boom
"Boom" is a term which specifically refers to the tower crane's working arm. The boom is made of steel parts connected together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the bottom that can run the length of the boom. This particular trolley has the hoisting device.
