Parts of a Tower Crane
Some of the most amazing structures throughout the globe are built utilizing cranes. The newer cranes are utilized in order to reach higher heights. Tower cranes provide the way to move and raise supplies, tools and building parts around a construction site. There are a few different parts which assemble a tower crane when they are put together. Putting a tower crane together utilizes various pieces of construction machinery.
Usually, 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 kind of set-up provides the structure with stability. Generally, the construction has to be well engineered and built in order to operate at optimum safety.
The mast of the tower crane provides height to the machine. The mast is made of connected steel parts. The amount of sections determines the crane's height. Typically, a tower crane has a design which allows 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, ensuring it has sufficient 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 machinery that allows the crane to rotate. A top climber is the piece of machine that allows the mast to grow. The top climber sits just beneath the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be detached from the mast by raising it higher.
"Boom" is a term which specifically refers to the tower crane's working arm. The boom is made of steel sections attached together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the bottom which could run the length of the boom. This particular trolley holds the hoisting mechanism.
