Tower Crane Parts
Tower cranes allow the construction industry to build some wonderful structures. These cranes have been designed to reach ever-increasing heights. Tower cranes offer the means to transport and raise materials, tools and building parts all over a construction location. There are a few different parts which assemble a tower crane once they are put together. Putting a tower crane together uses various pieces of construction machines.
Base
The tower crane base is normally made from a steel unit. The base of the unit connects to a custom pad made of concrete. This set-up gives the structure stability. Overall, the construction must be engineered and built well so as 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 parts that are connected together. The amount of parts determines the height of the crane. Normally, a tower crane has a design which enables the mast to grow during construction by adding more sections as the building process continues. This way the height of the crane can be specified, ensuring it has sufficient height to carry out the needed work safely and efficiently.
Slewing Unit/Top Climber
A slewing unit is located over the mast. This unit houses the machines and the motor which allows the crane to rotate. A top climber is the piece of equipment which enables 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
The term "boom", refers to the tower crane's working arm. The boom is made up of separate steel parts that are attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the underside that could extend the length of the boom. This particular trolley has the hoisting device.
