Parts of a Tower Crane
Some of the most amazing structures around the world are built utilizing cranes. The newer cranes are used to be able to reach higher heights. Tower cranes provide the way to transport and raise tools, building parts and supplies around a construction site. 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 machines.
Base
The tower crane base is usually made from a steel unit. The base of the unit connects to a custom pad made of concrete. This set-up gives the structure stability. Generally, the construction must be well engineered and built in order to operate at optimum safety.
Mast
The tower cranes mast provides height to the machine. The mast is made of attached steel parts. The amount of parts determines the height of the crane. Usually, a tower crane has a design that allows the mast to grow during construction by adding further sections as the building process continues. This way the height of the crane could be specified, ensuring it has sufficient height to safely and efficiently perform the required work.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machinery which enables the crane to rotate. A top climber is the piece of machinery which enables the mast to grow. The top climber sits just below 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 tower crane's working arm. The boom is made up of separate steel parts that are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the base which could extend the length of the boom. This trolley holds the hoisting device.
