Parts of a Tower Crane
Tower cranes enable the construction industry to make several wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes provide the way to transport and raise supplies, tools and building parts around a construction site. There are various parts which assemble a tower crane once they are put together. Putting a tower crane together utilizes different pieces of construction equipment.
Base
Normally, the base of a tower crane is made from a steel unit. The base is connected to a custom-designed concrete pad. This set-up gives the structure stability. Overall, the construction should be well engineered and built so as to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machine. The mast is made of attached steel parts. The amount of sections determines the crane's height. Typically, a tower crane has a design that allows the mast to grow during construction by adding more parts as the building process goes on. This way the height of the crane can be specified, ensuring it has sufficient height to efficiently and safely perform the required work.
Slewing Unit/Top Climber
At the top of 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 machine that enables the mast to grow. The top climber is situated 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 separate steel parts which 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 that could run the length of the boom. This trolley holds the hoisting mechanism.
