Parts of a Tower Crane
Tower cranes allow the construction industry to make several incredible structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the way to transport and lift materials, tools and building parts around a construction site. There are a few different components which assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction machinery.
Base
Usually, the base of a tower crane is made from a steel unit. The base is attached to a custom-designed concrete pad. This type of set-up gives the structure stability. Overall, the construction needs to be engineered and built well so as to operate at optimum safety.
Mast
The mast of the tower crane provides height to the equipment. The mast is made of attached steel parts. The amount of parts determines the crane's height. Typically, a tower crane has a design that enables the mast to grow during construction by adding further parts as the building process continues. This way the height of the crane can be specified, ensuring it has enough height to perform the required work efficiently and safely.
Slewing Unit/Top Climber
A slewing unit is situated above the mast. This unit houses the equipment and the motor that allows the crane to rotate. A top climber is the piece of equipment that allows the mast to grow. The top climber is situated just below the slewing unit. Hydraulic rams inside the top climber allow the slewing unit to be disconnected from the mast by raising it higher.
Boom
"Boom" is a term that particularly refers to the tower crane's working arm. 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 attached to the underside that can extend the length of the boom. This particular trolley has the hoisting device.
