Parts of a Tower Crane
Several of the most remarkable structures throughout the world are made utilizing cranes. The newer cranes are used in order to reach higher heights. Tower cranes offer the means to raise and move building parts, supplies and tools around a construction location. There are various components that assemble a tower crane when they are put together. Putting a tower crane together utilizes various pieces of construction machines.
Base
Normally, the tower crane base is made from a steel unit. The base is attached to a custom-designed concrete pad. This kind of set-up provides the structure with stability. Generally, the construction must be engineered and constructed well so as to operate at optimum safety.
Mast
The tower cranes mast provides height to the machinery. The mast is made of attached steel parts. The amount of parts determines the height of the crane. Normally, a tower crane has a design which allows the mast to grow during construction by adding further sections as the building process goes on. This way the crane's height could be specified, ensuring it has enough height to carry out the needed work safely and efficiently.
Slewing Unit/Top Climber
Over the mast is the slewing unit. It houses the motor and machinery which allows the crane to rotate. A top climber is the piece of machinery which enables the mast to grow. The top climber sits just below 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 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 connected to the underside which could run the length of the boom. This particular trolley has the hoisting mechanism.
