Tower Crane Parts
Some of the most amazing structures throughout the world are made with cranes. The newer cranes are designed to be able to reach higher heights. Tower cranes provide the means to lift and transport supplies, tools and building parts all over a construction location. There are various parts that assemble a tower crane when they are put together. Putting a tower crane together uses various pieces of construction equipment.
Base
The tower crane base is typically made from a steel unit. The units' base attaches to a custom pad made of concrete. This set-up gives the structure stability. Overall, the construction has to be well engineered and built in order to operate at optimum safety.
Mast
The tower crane's mast provides the equipment with its overall height. The mast is constructed out of separate steel parts which are attached together. The amount of sections determines the height of the crane. Usually, a tower crane has a design which allows the mast to grow during construction by adding more sections as the building process continues. This way the height of the crane can be specified, ensuring it has adequate height to perform the needed work safely and efficiently.
Slewing Unit/Top Climber
At the top of the mast is the slewing unit. It houses the motor and machines which 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 beneath the slewing unit. Hydraulic rams inside 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 attached to the base which can run the length of the boom. This trolley has the hoisting device.
