Parts of a Tower Crane
Tower cranes enable the construction industry to build several wonderful structures. These cranes have been designed to reach ever-increasing heights. Tower cranes provide the way to move and lift building parts, supplies and tools around a construction site. There are various parts that assemble a tower crane when they are put together. Putting a tower crane together utilizes different pieces of construction machinery.
Base
Typically, the tower crane base is made from a steel unit. The base is connected to a custom-designed concrete pad. This set-up provides the structure with stability. Overall, the construction should be well engineered and constructed in order 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. Typically, a tower crane has a design that enables the mast to grow during construction by adding more sections as the building process goes on. This way the crane's height can 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 at the top of the mast. This unit houses the machinery and the motor which allows the crane to rotate. A top climber is the piece of machinery that enables the mast to grow. The top climber is located 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 tower crane's working arm. 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 that could run the length of the boom. This trolley holds the hoisting device.
