Parts of a Tower Crane
Several of the most wonderful structures around the globe are made using cranes. The newer cranes are designed in order to reach higher heights. Tower cranes offer the way to raise and move building parts, supplies and tools all over a construction location. There are various parts that assemble a tower crane once they are put together. Putting a tower crane together uses various pieces of construction equipment.
Base
The base of a tower crane is normally made from a steel unit. The units' base connects to a custom pad made of concrete. This set-up gives the structure stability. Generally, the construction must be well engineered and constructed in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machinery. The mast is made of attached steel parts. The amount of sections determines the crane's height. Usually, a tower crane has a design which allows the mast to grow during construction by adding further parts as the building process goes on. This way the height of the crane can be specified, making certain that it has enough height to carry out the required work efficiently and safely.
Slewing Unit/Top Climber
At the top of the mast is the slewing unit. It houses the motor and machinery which enables 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 which particularly refers to the working arm of a tower crane. The boom is made of steel sections connected together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the bottom that can extend the length of the boom. This particular trolley has the hoisting mechanism.
