Tower Crane Parts
Tower cranes allow the construction industry to make various wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the means to raise and transport building parts, supplies and tools all around a construction location. There are several different components which assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction machinery.
Base
The tower crane base is usually made from a steel unit. The units' base connects to a custom pad made of concrete. This set-up provides the structure with stability. Overall, the construction needs to be engineered and constructed well 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 individual steel sections that are attached together. The amount of sections determines the height of the crane. Usually, a tower crane has a design that allows 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 sufficient height to safely and efficiently carry out the needed work.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machines which 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 detached from the mast by raising it higher.
Boom
The term "boom", refers to the tower crane's working arm. The boom is made up of individual steel parts which are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the base which can run the length of the boom. This particular trolley holds the hoisting mechanism.
