Tower Crane Parts
Tower cranes enable the construction industry to build some amazing structures. These cranes have been designed to reach ever-increasing heights. Tower cranes provide the means to raise and move tools, building parts and supplies all around a construction site. There are several different parts which 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 normally made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This type of set-up gives the structure stability. Generally, the construction should be well engineered and constructed so as to operate at optimum safety.
Mast
The mast of the tower crane provides height to the equipment. The mast is made of connected steel sections. The amount of sections determines the crane's height. Normally, 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 height of the crane can be specified, making certain that it has sufficient height to carry out the required work efficiently and safely.
Slewing Unit/Top Climber
Above the mast is the slewing unit. It houses the motor and equipment that enables the crane to rotate. A top climber is the piece of machinery which allows the mast to grow. The top climber sits just below 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 that particularly refers to the working arm of a tower crane. The boom is made of steel parts attached together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the base which could extend the length of the boom. This particular trolley holds the hoisting mechanism.
