Tower Crane Parts
Some of the most wonderful structures around the globe are made using cranes. The newer cranes are used in order to reach higher heights. Tower cranes offer the way to lift and transport building parts, supplies and tools around a construction location. There are a few different components which assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machines.
Base
Typically, the tower crane base is made from a steel unit. The base is attached to a custom-designed concrete pad. This type of set-up gives the structure stability. Generally, the construction should be well engineered and constructed so as to operate at optimum safety.
Mast
The mast on the tower crane provides the equipment with its overall height. The mast is constructed out of individual steel parts which are attached together. The amount of sections determines the crane's height. Normally, 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 crane's height can be specified, making sure that it has enough height to efficiently and safely perform the needed work.
Slewing Unit/Top Climber
Above 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 equipment which enables 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 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 sections 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 particular trolley has the hoisting mechanism.
