Parts of a Tower Crane
Tower cranes enable the construction industry to make some incredible structures. These cranes have been designed to reach ever-increasing heights. Tower cranes offer the way to transport and raise supplies, tools and building parts all over a construction location. There are a few different parts that assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction equipment.
Base
The base of a tower crane is normally made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This set-up gives the structure stability. Generally, the construction should be well engineered and built so as to operate at optimum safety.
Mast
The tower cranes mast provides height to the equipment. The mast is made of connected steel parts. The amount of sections 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, making sure that it has adequate height to safely and efficiently carry out the required work.
Slewing Unit/Top Climber
A slewing unit is situated over the mast. This unit houses the equipment and the motor which allows the crane to rotate. A top climber is the piece of machine that allows the mast to grow. The top climber is located just below 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 which 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 attached to the bottom which can run the length of the boom. This trolley holds the hoisting mechanism.
