Tower Crane Parts
Tower cranes allow the construction industry to make some wonderful structures. These cranes have been utilized to reach ever-increasing heights. Tower cranes provide the way to move and lift building parts, materials and tools around a construction site. There are several different components which assemble a tower crane once they are put together. Putting a tower crane together uses various pieces of construction machinery.
Base
The tower crane base is typically made from a steel unit. The base of the unit connects to a custom pad made of concrete. This set-up provides the structure with stability. Generally, the construction must be engineered and constructed well so as to operate at optimum safety.
Mast
The mast on the tower crane provides the machinery with its overall height. The mast is constructed out of separate steel parts which are attached together. The amount of parts determines the height of the crane. Typically, a tower crane has a design which enables the mast to grow during construction by adding more parts as the building process continues. This way the crane's height can be specified, ensuring it has adequate height to carry out the required work efficiently and safely.
Slewing Unit/Top Climber
A slewing unit is situated above the mast. This unit houses the machinery and the motor that allows the crane to rotate. A top climber is the piece of equipment which allows 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 parts attached together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the base which could run the length of the boom. This particular trolley holds the hoisting mechanism.
