Parts of a Tower Crane
Tower cranes enable the construction industry to build various wonderful structures. These cranes have been utilized to reach ever-increasing heights. Tower cranes offer the means to move and raise tools, building parts and materials all over a construction site. There are various components that assemble a tower crane when they are put together. Putting a tower crane together utilizes various pieces of construction machinery.
Base
Normally, the tower crane base is made from a steel unit. The base is attached to a custom-designed concrete pad. This kind of set-up provides the structure with stability. Overall, the construction must be well engineered and constructed in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the equipment. The mast is made of attached steel parts. 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 further parts as the building process continues. This way the crane's height can be specified, making sure that it has adequate 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 machinery which enables the crane to rotate. A top climber is the piece of machine which allows the mast to grow. The top climber is located just underneath the slewing unit. Hydraulic rams inside the top climber allow 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 connected 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 particular trolley has the hoisting device.
