Parts of a Tower Crane
Several of the most amazing structures around the globe are made with cranes. The newer cranes are designed in order to reach higher heights. Tower cranes provide the way to raise and move building parts, supplies and tools all over a construction location. There are a few different parts which assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction machines.
Base
Usually, the base of a tower crane is made from a steel unit. The base is attached to a concrete pad that is custom-designed. This kind of set-up provides the structure with stability. Generally, the construction has to be well engineered and constructed in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machinery. The mast is made of attached steel parts. The amount of parts determines the height of the crane. Typically, a tower crane has a design that allows the mast to grow during construction by adding more parts as the building process goes on. This way the crane's height could be specified, making sure that it has adequate height to safely and efficiently perform the needed work.
Slewing Unit/Top Climber
A slewing unit is situated at the top of the mast. This unit houses the equipment and the motor which enables the crane to rotate. A top climber is the piece of equipment that allows the mast to grow. The top climber sits just beneath the slewing unit. Hydraulic rams inside the top climber allow the slewing unit to be detached 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 connected together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the underside that can extend the length of the boom. This trolley has the hoisting device.
