Tower Crane Parts
Several of the most amazing structures around the world are made with cranes. The newer cranes are used in order to reach higher heights. Tower cranes offer the means to lift and move materials, tools and building parts all over a construction location. There are various parts that assemble a tower crane when they are put together. Putting a tower crane together uses various pieces of construction machines.
Base
Typically, the tower crane base is made from a steel unit. The base is connected to a concrete pad that is custom-designed. This set-up provides the structure with stability. Generally, the construction should be well engineered and built in order to operate at optimum safety.
Mast
The tower crane's mast provides the machine 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. Usually, a tower crane has a design which enables the mast to grow during construction by adding more sections as the building process goes on. This way the crane's height can be specified, ensuring it has enough height to efficiently and safely carry out the required work.
Slewing Unit/Top Climber
A slewing unit is situated over the mast. This unit houses the machinery and the motor which enables the crane to rotate. A top climber is the piece of machinery that allows the mast to grow. The top climber sits just beneath 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 which particularly refers to the working arm of a tower crane. 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 bottom which could run the length of the boom. This particular trolley holds the hoisting mechanism.
