Parts of a Tower Crane
Some of the most remarkable structures throughout the globe are made with cranes. The newer cranes are used in order to reach higher heights. Tower cranes provide the way to transport and raise materials, tools and building parts all around a construction location. There are a few different parts that assemble a tower crane when they are put together. Putting a tower crane together utilizes different pieces of construction equipment.
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 gives the structure stability. Generally, the construction needs to be well engineered and built in order to operate at optimum safety.
Mast
The tower cranes mast provides height to the machine. The mast is made of attached steel sections. The amount of sections determines the crane's height. Typically, a tower crane has a design which allows the mast to grow during construction by adding further parts as the building process goes on. This way the crane's height could be specified, making certain that it has sufficient height to carry out the required work safely and efficiently.
Slewing Unit/Top Climber
A slewing unit is located above the mast. This unit houses the machinery and the motor which 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 in the top climber enable the slewing unit to be detached 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 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 bottom which can extend the length of the boom. This particular trolley holds the hoisting mechanism.
