Parts of a Tower Crane
Some of the most wonderful structures throughout the globe are made using cranes. The newer cranes are designed in order to reach higher heights. Tower cranes offer the means to move and raise building parts, supplies and tools all 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 various pieces of construction equipment.
Base
The tower crane base is typically made from a steel unit. The units' base attaches to a custom pad made of concrete. This kind of set-up gives the structure stability. Generally, the construction should be engineered and constructed well so as 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 parts determines the height of the crane. Typically, a tower crane has a design which allows the mast to grow during construction by adding further parts as the building process continues. This way the crane's height can be specified, ensuring it has adequate height to efficiently and safely perform the required work.
Slewing Unit/Top Climber
A slewing unit is situated above the mast. This unit houses the equipment and the motor that enables the crane to rotate. A top climber is the piece of equipment that allows the mast to grow. The top climber sits just beneath the slewing unit. Hydraulic rams inside the top climber enable the slewing unit to be disconnected from the mast by raising it higher.
Boom
"Boom" is a term that specifically refers to the tower crane's working arm. The boom is made of steel sections attached together, which extend out from the top of the slewing unit, parallel to the ground. There is a trolley connected to the underside that could run the length of the boom. This trolley has the hoisting device.
