Parts of a Tower Crane
Tower cranes allow the construction industry to make various incredible structures. These cranes have been designed to reach ever-increasing heights. Tower cranes provide the way to raise and transport tools, building parts and materials all over 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 machinery.
Base
Normally, the tower crane base is made from a steel unit. The base is attached to a concrete pad that is custom-designed. This set-up gives the structure stability. Overall, the construction needs to 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 individual steel sections that are attached together. The amount of sections determines the crane's height. Usually, a tower crane has a design that enables the mast to grow during construction by adding further parts as the building process continues. This way the crane's height can be specified, making certain that it has sufficient height to carry out the required work efficiently and safely.
Slewing Unit/Top Climber
Over 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 machine which enables the mast to grow. The top climber sits just beneath 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 that particularly refers to the working arm of a tower crane. The boom is made of steel sections connected together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the underside which can extend the length of the boom. This particular trolley holds the hoisting mechanism.
