Parts of a Tower Crane
Some of the most amazing structures throughout the world are built using cranes. The newer cranes are utilized to be able to reach higher heights. Tower cranes offer the means to move and raise supplies, tools and building parts all around a construction location. There are a few different parts that assemble a tower crane once they are put together. Putting a tower crane together uses different pieces of construction machinery.
Base
Typically, the base of a tower crane is made from a steel unit. The base is attached to a concrete pad that is custom-designed. This set-up provides the structure with stability. Overall, the construction has to 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 parts determines the crane's height. Typically, a tower crane has a design which allows the mast to grow during construction by adding further sections as the building process continues. This way the crane's height could be specified, making sure that it has adequate height to perform the needed work efficiently and safely.
Slewing Unit/Top Climber
Above the mast is the slewing unit. It houses the motor and machines that allows the crane to rotate. A top climber is the piece of machine which enables the mast to grow. The top climber is located just beneath 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 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 attached to the underside which can run the length of the boom. This trolley has the hoisting device.
