Parts of a Tower Crane
Some of the most amazing structures around the world are made using cranes. The newer cranes are designed to be able to reach higher heights. Tower cranes offer the means to transport and raise building parts, materials and tools all around a construction site. There are various parts which assemble a tower crane once they are put together. Putting a tower crane together utilizes different pieces of construction machines.
Base
The base of a tower crane is normally made from a steel unit. The units' base attaches to a custom pad made of concrete. This set-up gives the structure stability. Generally, the construction must be engineered and built well so as to operate at optimum safety.
Mast
The mast of the tower crane provides height to the equipment. The mast is made of attached steel parts. The amount of sections determines the height of the crane. Normally, a tower crane has a design that enables the mast to grow during construction by adding more parts as the building process goes on. This way the height of the crane can be specified, ensuring it has sufficient height to efficiently and safely carry out the required work.
Slewing Unit/Top Climber
At the top of the mast is the slewing unit. It houses the motor and machinery that enables the crane to rotate. A top climber is the piece of equipment which enables the mast to grow. The top climber is situated just underneath 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 sections which are attached together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the bottom which could run the length of the boom. This particular trolley has the hoisting device.
