Parts of a Tower Crane
Tower cranes allow the construction industry to build various amazing structures. These cranes have been designed to reach ever-increasing heights. Tower cranes offer the means to transport and lift supplies, tools and building parts all around a construction location. There are a few different parts which assemble a tower crane when they are put together. Putting a tower crane together utilizes various pieces of construction equipment.
Base
The base of a tower crane is typically made from a steel unit. The units' base connects to a custom pad made of concrete. This set-up gives the structure stability. Overall, the construction needs to be well engineered and constructed in order to operate at optimum safety.
Mast
The mast of the tower crane provides height to the machine. 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 enables the mast to grow during construction by adding further parts as the building process continues. This way the crane's height could be specified, making sure that it has adequate height to safely and efficiently carry out the needed work.
Slewing Unit/Top Climber
A slewing unit is located over the mast. This unit houses the machinery and the motor which allows the crane to rotate. A top climber is the piece of equipment which enables the mast to grow. The top climber is situated just beneath the slewing unit. Hydraulic rams inside the top climber enable the slewing unit to be detached 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 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 can extend the length of the boom. This trolley holds the hoisting mechanism.
