Parts of a Tower Crane
Several of the most amazing structures around the globe are made using cranes. The newer cranes are utilized in order to reach higher heights. Tower cranes provide the means to raise and move tools, building parts and materials all over a construction location. There are several different components which assemble a tower crane when they are put together. Putting a tower crane together uses various pieces of construction machinery.
Base
Normally, the base of a tower crane is made from a steel unit. The base is attached to a custom-designed concrete pad. This set-up provides the structure with stability. Overall, the construction needs to be engineered and constructed well in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machinery. The mast is made of connected steel parts. 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 parts as the building process continues. This way the crane's height can be specified, ensuring it has adequate height to safely and efficiently perform the required work.
Slewing Unit/Top Climber
At the top of the mast is the slewing unit. It houses the motor and equipment which allows the crane to rotate. A top climber is the piece of equipment that allows the mast to grow. The top climber sits just underneath the slewing unit. Hydraulic rams in the top climber allow the slewing unit to be detached from the mast by raising it higher.
Boom
The term "boom", refers to the working arm of a tower crane. The boom is made up of separate steel sections which are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the base which can run the length of the boom. This particular trolley has the hoisting mechanism.
