Parts of a Tower Crane
Some of the most wonderful structures around the world are built with cranes. The newer cranes are utilized to be able to reach higher heights. Tower cranes provide the means to move and lift materials, tools and building parts all 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 different pieces of construction equipment.
Base
Typically, the tower crane base is made from a steel unit. The base is connected to a concrete pad that is custom-designed. This type of set-up provides the structure with stability. Generally, the construction needs to be well engineered and constructed so as to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machinery. The mast is made of connected steel sections. The amount of sections determines the crane's height. Typically, a tower crane has a design that allows the mast to grow during construction by adding more parts as the building process goes on. This way the height of the crane could be specified, ensuring it has adequate height to safely and efficiently carry out the required work.
Slewing Unit/Top Climber
A slewing unit is situated above the mast. This unit houses the equipment and the motor which enables the crane to rotate. A top climber is the piece of machine which enables 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
"Boom" is a term which particularly refers to the working arm of a tower crane. The boom is made of steel sections connected together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the base that can extend the length of the boom. This particular trolley holds the hoisting device.
