Parts of a Tower Crane
Several of the most amazing structures throughout the globe are built utilizing cranes. The newer cranes are designed in order to reach higher heights. Tower cranes provide the way to raise and move tools, building parts and supplies all around a construction site. There are various components that assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction equipment.
Base
The base of a tower crane is typically made from a steel unit. The units' base connects to a custom pad made of concrete. This kind of set-up gives the structure stability. Overall, the construction should be well engineered and constructed so as to operate at optimum safety.
Mast
The tower crane's mast provides the equipment with its overall height. The mast is constructed out of individual steel sections that are connected together. The amount of sections determines the crane's height. Usually, a tower crane has a design which allows the mast to grow during construction by adding further parts as the building process goes on. This way the crane's height can be specified, making sure that 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 machines that allows the crane to rotate. A top climber is the piece of equipment that allows the mast to grow. The top climber is located just beneath the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be disconnected from the mast by raising it higher.
Boom
The term "boom", refers to the working arm of a tower crane. The boom is made up of individual steel parts that 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 which could run the length of the boom. This particular trolley holds the hoisting device.
