Parts of a Tower Crane
Tower cranes enable the construction industry to build various amazing structures. These cranes have been used to reach ever-increasing heights. Tower cranes offer the way to lift and transport supplies, tools and building parts around a construction location. There are various parts which assemble a tower crane once they are put together. Putting a tower crane together uses different pieces of construction machines.
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 set-up gives the structure stability. Generally, 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 machine. The mast is made of attached steel sections. The amount of sections determines the height of the crane. Usually, 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 could be specified, making sure that it has adequate height to safely and efficiently carry out the required work.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the machines and the motor that enables the crane to rotate. A top climber is the piece of machine that enables 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
The term "boom", refers to the tower crane's working arm. The boom is made up of individual steel sections 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 underside that can run the length of the boom. This particular trolley has the hoisting device.
