Parts of a Tower Crane
Some of the most remarkable structures throughout the globe are built utilizing cranes. The newer cranes are used to be able to reach higher heights. Tower cranes offer the way to lift and transport tools, building parts and materials all around a construction site. There are several different components that assemble a tower crane once they are put together. Putting a tower crane together uses different pieces of construction machines.
Base
Normally, the tower crane base is made from a steel unit. The base is attached to a custom-designed concrete pad. This set-up provides the structure with stability. Overall, the construction needs to be engineered and constructed well so as to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machinery. The mast is made of connected steel sections. The amount of sections determines the crane's height. Normally, a tower crane has a design that allows the mast to grow during construction by adding more parts as the building process goes on. This way the height of the crane could be specified, ensuring it has adequate height to carry out the needed work efficiently and safely.
Slewing Unit/Top Climber
At the top of the mast is the slewing unit. It houses the motor and equipment that allows the crane to rotate. A top climber is the piece of machinery which allows the mast to grow. The top climber is situated just below 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 that particularly refers to the working arm of a tower crane. The boom is made of steel sections attached together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the bottom that can run the length of the boom. This particular trolley holds the hoisting device.
