Parts of a Tower Crane
Some of the most wonderful structures throughout the globe are built using cranes. The newer cranes are used in order to reach higher heights. Tower cranes offer the means to lift and move building parts, materials and tools around a construction site. There are various components which assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machinery.
Base
Typically, 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 should be well engineered and constructed in order to operate at optimum safety.
Mast
The tower crane's mast provides the machinery with its overall height. The mast is constructed out of separate steel sections that are attached together. The amount of parts determines the crane's height. Typically, a tower crane has a design that allows the mast to grow during construction by adding further parts as the building process goes on. This way the crane's height can be specified, making certain that it has adequate height to perform the required work efficiently and safely.
Slewing Unit/Top Climber
A slewing unit is situated over the mast. This unit houses the machines and the motor that allows the crane to rotate. A top climber is the piece of machinery which allows the mast to grow. The top climber is located 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 specifically refers to the tower crane's working arm. The boom is made of steel parts attached together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the underside which can run the length of the boom. This particular trolley has the hoisting mechanism.
