Parts of a Tower Crane
Tower cranes enable the construction industry to build several incredible structures. These cranes have been designed to reach ever-increasing heights. Tower cranes provide the means to move and lift tools, building parts and materials all around a construction site. There are several different components that assemble a tower crane when they are put together. Putting a tower crane together uses various pieces of construction machinery.
Base
The base of a tower crane is normally made from a steel unit. The units' base connects to a custom pad made of concrete. This kind of set-up provides the structure with stability. Overall, the construction needs to be engineered and constructed well so as to operate at optimum safety.
Mast
The tower crane's mast provides the machinery with its overall height. The mast is built out of individual steel sections that are attached together. The amount of sections determines the crane's height. Normally, a tower crane has a design which allows the mast to grow during construction by adding further parts as the building process goes on. This way the height of the crane could be specified, ensuring it has enough height to perform the required work safely and efficiently.
Slewing Unit/Top Climber
A slewing unit is located over the mast. This unit houses the machines and the motor which allows the crane to rotate. A top climber is the piece of machine that allows the mast to grow. The top climber is situated just below the slewing unit. Hydraulic rams in the top climber enable the slewing unit to be disconnected from the mast by raising it higher.
Boom
The term "boom", refers to the tower crane's working arm. The boom is made up of individual steel parts that 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 which could run the length of the boom. This trolley has the hoisting mechanism.
