Parts of a Tower Crane
Several of the most wonderful structures around the world are built with cranes. The newer cranes are used to be able to reach higher heights. Tower cranes provide the way to transport and raise building parts, materials and tools around a construction site. There are several different parts that assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction equipment.
Base
Normally, the tower crane base is made from a steel unit. The base is connected to a concrete pad that is custom-designed. This kind of set-up gives the structure stability. Overall, the construction should be engineered and constructed well so as to operate at optimum safety.
Mast
The tower crane's mast provides the machine with its overall height. The mast is constructed out of separate steel parts that are attached together. The amount of parts determines the crane's height. Typically, a tower crane has a design that enables the mast to grow during construction by adding more sections as the building process continues. This way the crane's height could be specified, ensuring it has enough height to safely and efficiently carry out the needed work.
Slewing Unit/Top Climber
Over 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 equipment that allows the mast to grow. The top climber sits just underneath 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 which particularly refers to the tower crane's working arm. The boom is made of steel sections attached together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the bottom which could extend the length of the boom. This particular trolley has the hoisting device.
