Tower Crane Parts
Some of the most wonderful structures throughout the globe are built with cranes. The newer cranes are designed to be able to reach higher heights. Tower cranes offer the way to lift and transport tools, building parts and materials around a construction location. There are several different components that assemble a tower crane when they are put together. Putting a tower crane together uses different pieces of construction machinery.
Base
The base of a tower crane 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 has to be well engineered and built so as to operate at optimum safety.
Mast
The tower cranes mast provides height to the equipment. The mast is made of connected steel parts. The amount of sections determines the height of the crane. Normally, a tower crane has a design that allows the mast to grow during construction by adding further parts as the building process goes on. This way the crane's height can be specified, ensuring it has enough height to efficiently and safely carry out the needed work.
Slewing Unit/Top Climber
Above the mast is the slewing unit. It houses the motor and machinery which enables the crane to rotate. A top climber is the piece of machinery which enables the mast to grow. The top climber sits just underneath 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 separate steel sections which are connected together, extending out from the top of the slewing unit and parallel to the ground. There is a trolley connected to the bottom that can extend the length of the boom. This particular trolley holds the hoisting mechanism.
