Parts of a Tower Crane
Tower cranes enable the construction industry to build various wonderful structures. These cranes have been utilized to reach ever-increasing heights. Tower cranes provide the way to lift and move supplies, tools and building parts all over a construction location. There are several different parts which assemble a tower crane once they are put together. Putting a tower crane together utilizes different 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 type of set-up gives the structure stability. Generally, the construction has to be engineered and built well in order to operate at optimum safety.
Mast
The tower crane's mast provides the equipment with its overall height. The mast is built out of separate steel sections that are connected together. The amount of parts determines the height of the crane. Normally, a tower crane has a design which enables the mast to grow during construction by adding further sections as the building process goes on. This way the crane's height could be specified, ensuring it has enough height to safely and efficiently perform the needed work.
Slewing Unit/Top Climber
Above the mast is the slewing unit. It houses the motor and machinery 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 underneath the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be detached 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 individual 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 underside which could run the length of the boom. This trolley holds the hoisting device.
