Parts of a Tower Crane
Tower cranes allow the construction industry to make various wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes provide the means to move and lift tools, building parts and supplies around a construction location. There are several different components that assemble a tower crane once they are put together. Putting a tower crane together uses various pieces of construction equipment.
Base
Usually, 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 provides the structure with stability. Generally, the construction has to be engineered and constructed well so as to operate at optimum safety.
Mast
The mast on the tower crane provides the equipment with its overall height. The mast is constructed out of individual steel parts which are attached together. The amount of sections determines the height of the crane. Typically, a tower crane has a design that enables the mast to grow during construction by adding further sections as the building process goes on. This way the height of the crane could be specified, ensuring it has adequate height to perform the needed work efficiently and safely.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machinery that enables the crane to rotate. A top climber is the piece of machine which enables the mast to grow. The top climber is situated just underneath 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 parts 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.
