Tower Crane Parts
Several of the most wonderful structures around the world are built utilizing cranes. The newer cranes are used to be able to reach higher heights. Tower cranes offer the means to lift and transport building parts, materials and tools around a construction site. There are various components that assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction equipment.
Base
The base of a tower crane is typically made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This kind of 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 crane's mast provides the equipment 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. Usually, a tower crane has a design that allows the mast to grow during construction by adding further sections as the building process goes on. This way the height of the crane could be specified, ensuring it has adequate height to perform the needed work safely and efficiently.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machinery which enables the crane to rotate. A top climber is the piece of equipment that enables the mast to grow. The top climber sits just underneath the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be detached from the mast by raising it higher.
Boom
"Boom" is a term that particularly refers to the tower crane's working arm. The boom is made of steel sections connected together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the bottom that could extend the length of the boom. This particular trolley has the hoisting device.
