Parts of a Tower Crane
Some of the most remarkable structures throughout the world are built utilizing cranes. The newer cranes are utilized to be able to reach higher heights. Tower cranes provide the way to transport and raise supplies, tools and building parts around a construction location. There are several different components that assemble a tower crane when they are put together. Putting a tower crane together uses various pieces of construction machines.
Base
Usually, the tower crane base is made from a steel unit. The base is connected to a custom-designed concrete pad. This type of set-up provides the structure with stability. Overall, the construction needs to be well engineered and built so as to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machinery. The mast is made of attached steel sections. The amount of sections determines the height of the crane. Normally, a tower crane has a design that allows the mast to grow during construction by adding further sections as the building process goes on. This way the crane's height could be specified, ensuring it has enough height to safely and efficiently perform the required work.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the machinery and the motor that allows the crane to rotate. A top climber is the piece of machinery that enables the mast to grow. The top climber sits just underneath the slewing unit. Hydraulic rams inside the top climber allow the slewing unit to be disconnected from the mast by raising it higher.
Boom
"Boom" is a term that specifically refers to the tower crane's working arm. The boom is made of steel parts connected together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the bottom which can extend the length of the boom. This trolley has the hoisting mechanism.
