Tower Crane Parts
Several of the most wonderful structures around the world are built using cranes. The newer cranes are used to be able to reach higher heights. Tower cranes provide the means to lift and move building parts, materials and tools all over a construction site. There are a few different parts which assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction equipment.
Base
The base of a tower crane is usually made from a steel unit. The units' base connects to a custom pad made of concrete. This type of set-up gives the structure stability. Overall, the construction has to be well engineered and constructed so as to operate at optimum safety.
Mast
The mast on the tower crane provides the machine with its overall height. The mast is constructed out of individual steel sections that are attached together. 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 further sections as the building process continues. This way the crane's height can be specified, ensuring it has enough height to carry out the required work efficiently and safely.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machinery which allows the crane to rotate. A top climber is the piece of machine that allows 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 detached from the mast by raising it higher.
Boom
The term "boom", refers to the tower crane's working arm. The boom is made up of individual steel parts which are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the bottom which can extend the length of the boom. This particular trolley holds the hoisting mechanism.
