Tower Crane Parts
Tower cranes enable the construction industry to build some incredible structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the means to lift and transport building parts, materials and tools around a construction site. There are various components which assemble a tower crane once they are put together. Putting a tower crane together utilizes various pieces of construction machines.
Base
Normally, the tower crane base is made from a steel unit. The base is connected to a custom-designed concrete pad. This type of set-up provides the structure with stability. Generally, the construction must be well engineered and built in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the equipment. The mast is made of connected steel sections. 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 more sections as the building process continues. This way the crane's height can be specified, ensuring it has enough 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 which allows the crane to rotate. A top climber is the piece of machinery which allows the mast to grow. The top climber sits just below the slewing unit. Hydraulic rams inside the top climber enable the slewing unit to be disconnected from the mast by raising it higher.
Boom
"Boom" is a term that specifically refers to the working arm of a tower crane. The boom is made of steel parts connected together, that extend out from the top of the slewing unit, parallel to the ground. There is a trolley attached to the base that can run the length of the boom. This trolley has the hoisting device.
