Parts of a Tower Crane
Tower cranes allow the construction industry to make various amazing structures. These cranes have been designed to reach ever-increasing heights. Tower cranes offer the way to move and lift 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 various pieces of construction equipment.
Base
Usually, the base of a tower crane is made from a steel unit. The base is attached to a concrete pad that is custom-designed. This set-up provides the structure with stability. Generally, the construction should be engineered and built well so as to operate at optimum safety.
Mast
The tower crane's mast provides the machine with its overall height. The mast is constructed out of individual steel sections which are attached together. The amount of sections determines the height of the crane. Normally, a tower crane has a design which 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 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 equipment which enables the mast to grow. The top climber is situated just below the slewing unit. Hydraulic rams inside 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 tower crane's working arm. The boom is made of steel sections connected together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the bottom which can extend the length of the boom. This particular trolley has the hoisting device.
