Parts of a Tower Crane
Tower cranes enable the construction industry to make various wonderful structures. These cranes have been designed to reach ever-increasing heights. Tower cranes provide the means to move and lift tools, building parts and materials all over a construction site. There are various parts which assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machinery.
Base
Normally, the tower crane base is made from a steel unit. The base is attached to a custom-designed concrete pad. This kind of set-up gives the structure stability. Overall, the construction should be engineered and built well in order to operate at optimum safety.
Mast
The tower crane's mast provides the machine with its overall height. The mast is constructed out of separate steel parts that are connected together. 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 enough height to carry out the needed work efficiently and safely.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the machinery and the motor which enables the crane to rotate. A top climber is the piece of equipment that allows the mast to grow. The top climber sits just underneath the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be detached 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 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 trolley has the hoisting device.
