Parts of a Tower Crane
Some of the most amazing structures around the globe are built using cranes. The newer cranes are used to be able to reach higher heights. Tower cranes offer the means to transport and raise supplies, tools and building parts around a construction site. There are several different components that assemble a tower crane when they are put together. Putting a tower crane together utilizes different pieces of construction machines.
Base
Typically, the base of a tower crane is made from a steel unit. The base is connected to a concrete pad that is custom-designed. This type of set-up provides the structure with stability. Generally, the construction has to be engineered and constructed well in order to operate at optimum safety.
Mast
The tower cranes mast provides height to the equipment. The mast is made of attached steel sections. The amount of sections determines the height of the crane. Usually, a tower crane has a design that enables 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, ensuring it has adequate height to efficiently and safely carry out the needed work.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the equipment and the motor which allows the crane to rotate. A top climber is the piece of machinery that allows the mast to grow. The top climber is situated just below the slewing unit. Hydraulic rams inside the top climber allow the slewing unit to be detached from the mast by raising it higher.
Boom
"Boom" is a term that specifically refers to the working arm of a tower crane. The boom is made of steel parts attached together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the base which could extend the length of the boom. This trolley holds the hoisting mechanism.
