Parts of a Tower Crane
Several of the most wonderful structures around the globe are built utilizing cranes. The newer cranes are designed in order to reach higher heights. Tower cranes provide the means to raise and move building parts, materials and tools around a construction site. There are various parts which assemble a tower crane once they are put together. Putting a tower crane together uses different pieces of construction machinery.
Base
Usually, the tower crane base is made from a steel unit. The base is attached to a concrete pad that is custom-designed. This kind of 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 crane's mast provides the equipment with its overall height. The mast is built out of individual steel sections which are connected together. The amount of sections determines the crane's height. Normally, a tower crane has a design which allows the mast to grow during construction by adding further parts as the building process goes on. This way the crane's height can be specified, ensuring it has adequate height to safely and efficiently perform the required work.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machinery which allows the crane to rotate. A top climber is the piece of machine that allows the mast to grow. The top climber is located just below 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 attached to the underside that could run the length of the boom. This trolley holds the hoisting device.
