Parts of a Tower Crane
Tower cranes allow the construction industry to build several wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the way to transport and lift tools, building parts and materials all around a construction location. 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 equipment.
Base
Normally, the base of a tower crane is made from a steel unit. The base is connected to a custom-designed concrete pad. This type of set-up gives the structure stability. Overall, the construction needs to be well engineered and built so as to operate at optimum safety.
Mast
The mast on the tower crane provides the machinery with its overall height. The mast is built out of separate steel sections that are connected together. The amount of sections determines the crane's height. Typically, a tower crane has a design that enables the mast to grow during construction by adding further sections as the building process continues. This way the height of the crane can be specified, making sure that it has sufficient height to efficiently and safely perform the required work.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the machines and the motor which enables the crane to rotate. A top climber is the piece of equipment that enables the mast to grow. The top climber sits just below the slewing unit. Hydraulic rams inside the top climber allow the slewing unit to be disconnected 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 separate steel parts that are attached together, extending out from the top of the slewing unit and 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 mechanism.
