Parts of a Tower Crane
Several of the most wonderful structures around the world are made with cranes. The newer cranes are utilized to be able to reach higher heights. Tower cranes offer the means to transport and raise supplies, tools and building parts around a construction location. There are various parts that assemble a tower crane once they are put together. Putting a tower crane together utilizes different pieces of construction machines.
Base
The tower crane base is normally made from a steel unit. The base of the unit attaches to a custom pad made of concrete. This type of set-up gives the structure stability. Generally, the construction needs to 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 parts. The amount of sections determines the height of the crane. Typically, a tower crane has a design that 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, making sure that it has enough height to perform the required work safely and efficiently.
Slewing Unit/Top Climber
A slewing unit is situated over the mast. This unit houses the machines and the motor that enables the crane to rotate. A top climber is the piece of equipment which enables the mast to grow. The top climber is located just underneath 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 sections that are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley attached to the bottom which can run the length of the boom. This particular trolley has the hoisting device.
