Tower Crane Parts
Tower cranes enable the construction industry to build several wonderful structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the means to transport and lift tools, building parts and supplies all around a construction site. There are a few different parts that assemble a tower crane once they are put together. Putting a tower crane together uses various pieces of construction equipment.
Base
The base of a tower crane is usually made from a steel unit. The base of the unit connects to a custom pad made of concrete. This set-up provides the structure with stability. Overall, the construction should be well engineered and built so as 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 height of the crane. Usually, a tower crane has a design which allows the mast to grow during construction by adding more parts as the building process continues. This way the height of the crane could be specified, ensuring it has sufficient height to efficiently and safely perform the required work.
Slewing Unit/Top Climber
Above the mast is the slewing unit. It houses the motor and machines that 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 in the top climber allow the slewing unit to be disconnected 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 individual 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 underside which can extend the length of the boom. This particular trolley has the hoisting mechanism.
