Parts of a Tower Crane
Some of the most wonderful structures around the world are built utilizing cranes. The newer cranes are designed to be able to reach higher heights. Tower cranes provide the means to lift and move supplies, tools and building parts around a construction site. There are a few different parts which assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machines.
Base
Normally, the tower crane base is made from a steel unit. The base is connected to a concrete pad that is custom-designed. This kind of set-up gives the structure stability. Generally, the construction should be well engineered and built so as to operate at optimum safety.
Mast
The tower cranes mast provides height to the machine. The mast is made of connected steel parts. The amount of sections determines the height of the crane. Typically, a tower crane has a design that allows the mast to grow during construction by adding further parts as the building process continues. This way the height of the crane could be specified, ensuring it has enough height to safely and efficiently perform the needed work.
Slewing Unit/Top Climber
A slewing unit is located at the top of the mast. This unit houses the machinery and the motor that allows 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 enable the slewing unit to be detached from the mast by raising it higher.
Boom
"Boom" is a term which specifically 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 underside that could extend the length of the boom. This particular trolley holds the hoisting device.
