Parts of a Tower Crane
Some of the most wonderful structures around the world are built with cranes. The newer cranes are used in order to reach higher heights. Tower cranes provide the means to move and raise tools, building parts and materials around a construction site. There are several different components which assemble a tower crane when they are put together. Putting a tower crane together utilizes various pieces of construction machines.
Base
The tower crane base is normally made from a steel unit. The units' base attaches to a custom pad made of concrete. This type of set-up provides the structure with stability. Overall, the construction has to be engineered and constructed well in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machinery. The mast is made of connected steel sections. The amount of parts determines the crane's height. Typically, a tower crane has a design which enables the mast to grow during construction by adding more sections as the building process goes on. This way the height of the crane could be specified, making sure that it has sufficient height to perform the required work efficiently and safely.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and equipment that allows the crane to rotate. A top climber is the piece of machine which 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 disconnected 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 parts attached together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the underside that can extend the length of the boom. This trolley has the hoisting mechanism.
