Parts of a Tower Crane
Tower cranes allow the construction industry to make several amazing structures. These cranes have been designed to reach ever-increasing heights. Tower cranes provide the way to lift and transport building parts, supplies and tools around a construction site. There are several different parts which assemble a tower crane when they are put together. Putting a tower crane together utilizes different pieces of construction machinery.
Base
The base of a tower crane is usually made from a steel unit. The units' base connects to a custom pad made of concrete. This set-up gives the structure stability. Generally, the construction must be engineered and built well in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machine. The mast is made of connected steel parts. The amount of parts determines the height of the crane. Usually, a tower crane has a design that enables the mast to grow during construction by adding more sections as the building process continues. This way the height of the crane could be specified, ensuring it has sufficient height to efficiently and safely carry out the needed work.
Slewing Unit/Top Climber
At the top of the mast is the slewing unit. It houses the motor and machinery that allows the crane to rotate. A top climber is the piece of machinery which enables the mast to grow. The top climber is located 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 which specifically refers to the working arm of a tower crane. The boom is made of steel sections 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 extend the length of the boom. This particular trolley holds the hoisting mechanism.
