Parts of a Tower Crane
Some of the most amazing structures throughout the world are built using cranes. The newer cranes are used in order to reach higher heights. Tower cranes offer the way to transport and raise tools, building parts and supplies all around a construction location. There are several different components that assemble a tower crane when they are put together. Putting a tower crane together uses various pieces of construction machines.
Base
The base of a tower crane is normally made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This set-up gives the structure stability. Generally, the construction has to be well engineered and constructed in order to operate at optimum safety.
Mast
The mast on the tower crane provides the equipment with its overall height. The mast is constructed out of separate steel sections that are attached together. The amount of parts determines the height of the crane. Typically, a tower crane has a design that enables the mast to grow during construction by adding more parts as the building process goes on. This way the crane's height can be specified, ensuring it has enough height to safely and efficiently perform the needed work.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the machinery and the motor that enables the crane to rotate. A top climber is the piece of machine which enables the mast to grow. The top climber sits just below the slewing unit. Hydraulic rams in the top climber enable 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 trolley has the hoisting mechanism.
