Parts of a Tower Crane
Tower cranes enable the construction industry to make various wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the way to lift and move tools, building parts and materials all over a construction site. There are various parts that assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction machines.
Base
The base of a tower crane is typically made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This type of set-up provides the structure with stability. Generally, the construction should be engineered and built well in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the equipment. The mast is made of attached steel sections. The amount of parts determines the crane's height. Normally, a tower crane has a design which 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, making sure that it has enough 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 that enables the crane to rotate. A top climber is the piece of machinery which allows the mast to grow. The top climber sits just beneath the slewing unit. Hydraulic rams in the top climber enable 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 sections connected together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the base which could extend the length of the boom. This particular trolley has the hoisting device.
