Parts of a Tower Crane
Tower cranes enable the construction industry to make various amazing structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the means to raise and transport materials, tools and building parts all around a construction site. There are various parts which assemble a tower crane once they are put together. Putting a tower crane together utilizes different pieces of construction machinery.
Base
The base of a tower crane is typically made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This set-up provides the structure with stability. Generally, the construction has to be engineered and built well in order to operate at optimum safety.
Mast
The tower cranes mast provides height to the machinery. The mast is made of connected steel parts. The amount of sections determines the crane's height. Normally, a tower crane has a design which enables the mast to grow during construction by adding further sections as the building process goes on. This way the crane's height can be specified, making certain that it has enough height to perform the required work safely and efficiently.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machines which enables the crane to rotate. A top climber is the piece of machinery that allows the mast to grow. The top climber sits just underneath the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be disconnected from the mast by raising it higher.
Boom
The term "boom", refers to the working arm of a tower crane. The boom is made up of separate steel sections that are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the bottom that can run the length of the boom. This trolley holds the hoisting mechanism.
