Parts of a Tower Crane
Several of the most remarkable structures throughout the world are built utilizing 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 around a construction location. There are various components which assemble a tower crane once they are put together. Putting a tower crane together utilizes different pieces of construction machines.
Base
Typically, the tower crane base is made from a steel unit. The base is attached to a custom-designed concrete pad. This kind of set-up provides the structure with stability. Overall, the construction should be engineered and built well in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the equipment. The mast is made of attached steel parts. The amount of parts determines the height of the crane. Usually, a tower crane has a design that enables the mast to grow during construction by adding more sections as the building process continues. This way the crane's height can be specified, making sure that it has enough height to carry out the needed work safely and efficiently.
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 machinery which enables the mast to grow. The top climber is situated just beneath the slewing unit. Hydraulic rams inside the top climber allow the slewing unit to be disconnected from the mast by raising it higher.
Boom
"Boom" is a term that particularly refers to the tower crane's working arm. 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 underside which could extend the length of the boom. This particular trolley has the hoisting device.
