Parts of a Tower Crane
Several of the most amazing structures throughout the world are built using cranes. The newer cranes are designed to be able to reach higher heights. Tower cranes offer the means to lift and transport tools, building parts and materials all over a construction site. There are various components that assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machines.
Base
The tower crane base is normally made from a steel unit. The base of the unit connects to a custom pad made of concrete. This set-up gives the structure stability. Overall, the construction must be well engineered and constructed 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 parts determines the crane's height. Typically, a tower crane has a design that enables the mast to grow during construction by adding more parts as the building process continues. This way the height of the crane could be specified, ensuring it has sufficient height to efficiently and safely perform the needed work.
Slewing Unit/Top Climber
Above the mast is the slewing unit. It houses the motor and machines which enables the crane to rotate. A top climber is the piece of machinery which allows the mast to grow. The top climber is situated just beneath the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be disconnected from the mast by raising it higher.
Boom
"Boom" is a term which particularly refers to the working arm of a tower crane. The boom is made of steel parts attached together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the bottom which could run the length of the boom. This particular trolley has the hoisting mechanism.
