Tower Crane Parts
Tower cranes enable the construction industry to make some incredible structures. These cranes have been utilized to reach ever-increasing heights. Tower cranes provide the means to move and lift building parts, materials and tools around a construction site. There are a few different parts which assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction machinery.
Base
The base of a tower crane is typically made from a steel unit. The units' base attaches to a custom pad made of concrete. This kind of set-up provides the structure with stability. Overall, the construction must be engineered and built well in order 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 separate steel parts which are attached together. The amount of sections determines the height of the crane. Typically, a tower crane has a design which enables the mast to grow during construction by adding further sections as the building process goes on. This way the height of the crane can be specified, making sure that it has adequate height to safely and efficiently perform the needed work.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and equipment that allows the crane to rotate. A top climber is the piece of machine which allows 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 disconnected from the mast by raising it higher.
Boom
The term "boom", refers to the tower crane's working arm. The boom is made up of individual steel parts which are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the underside that could extend the length of the boom. This trolley holds the hoisting device.
