Parts of a Tower Crane
Several of the most remarkable structures around the globe are made with cranes. The newer cranes are designed to be able to reach higher heights. Tower cranes offer the means to move and raise supplies, tools and building parts all around a construction site. There are several different components that assemble a tower crane once they are put together. Putting a tower crane together uses various pieces of construction machinery.
Base
The base of a tower crane is usually made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This set-up provides the structure with stability. Overall, the construction should be well engineered and constructed so as to operate at optimum safety.
Mast
The tower cranes mast provides height to the equipment. The mast is made of connected steel parts. 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 height of the crane can be specified, ensuring it has adequate height to perform the required work efficiently and safely.
Slewing Unit/Top Climber
A slewing unit is located over the mast. This unit houses the machinery and the motor 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 beneath the slewing unit. Hydraulic rams in the top climber enable the slewing unit to be detached from the mast by raising it higher.
Boom
"Boom" is a term which particularly refers to the working arm of a tower crane. The boom is made of steel sections attached together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the base that could extend the length of the boom. This trolley has the hoisting device.
