Tower Crane Parts
Some of the most wonderful structures around the globe are built with cranes. The newer cranes are designed to be able to reach higher heights. Tower cranes provide the way to raise and transport building parts, supplies and tools all around a construction site. There are several different parts which assemble a tower crane once they are put together. Putting a tower crane together uses various pieces of construction machinery.
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 provides the structure with stability. Overall, the construction should be engineered and constructed well so as to operate at optimum safety.
Mast
The mast on the tower crane provides the machinery with its overall height. The mast is built out of individual steel parts that are connected together. The amount of sections determines the crane's height. Usually, a tower crane has a design which allows the mast to grow during construction by adding more parts as the building process continues. This way the height of the crane could be specified, making certain that it has adequate height to perform the needed work efficiently and safely.
Slewing Unit/Top Climber
A slewing unit is situated above the mast. This unit houses the equipment and the motor which enables the crane to rotate. A top climber is the piece of machine that enables the mast to grow. The top climber sits just beneath 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 that are attached 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 holds the hoisting mechanism.
