Parts of a Tower Crane
Tower cranes enable the construction industry to build some amazing structures. These cranes have been utilized to reach ever-increasing heights. Tower cranes offer the way to transport and lift supplies, tools and building parts all around a construction site. There are several different components that assemble a tower crane when they are put together. Putting a tower crane together utilizes various pieces of construction machines.
Base
Typically, the tower crane base is made from a steel unit. The base is attached to a custom-designed concrete pad. This set-up provides the structure with stability. Overall, the construction should be engineered and constructed well in order to operate at optimum safety.
Mast
The tower cranes mast provides height to the equipment. The mast is made of attached steel sections. The amount of parts determines the height of the crane. Typically, a tower crane has a design which enables the mast to grow during construction by adding more sections as the building process continues. This way the crane's height can be specified, ensuring it has enough height to carry out the needed work safely and efficiently.
Slewing Unit/Top Climber
Above the mast is the slewing unit. It houses the motor and equipment which allows the crane to rotate. A top climber is the piece of equipment which allows the mast to grow. The top climber sits just beneath the slewing unit. Hydraulic rams inside the top climber enable the slewing unit to be detached from the mast by raising it higher.
Boom
"Boom" is a term which specifically refers to the working arm of a tower crane. The boom is made of steel parts attached together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the underside that can extend the length of the boom. This trolley holds the hoisting device.
