Tower Crane Hire: How Does Erection Happen?

Looking hire a tower crane, do you actually know what a tower crane is?
Crane hire companies in Sydney offer a wide range of cranes for various applications, from small ones like pick-n-carry cranes and tight access cranes, up to those used in the construction industry, to construct high-rise buildings and skyscrapers, which are referred to as tower cranes.

Tower cranes are usually based on a concrete slab that is fixed to the ground with huge anchor bolts. The higher the crane gets, and the heavier the weight is, the supporting mechanism will be required to be attached to the sides of the building. 

Tower Crane Parts

When you are looking to hire a crane in Sydney, it is critical to understand the various parts that a crane would consist of. While these could differ from one to another, tower cranes are generally made up of 2 main parts:

  • Mast: this is considered the main tower of the crane, which is made out of steel trusses 
  • Slew: this is located at the top of the first part, giving it the ability to rotate

How Do Those Cranes Make it to the Top of Skyscrapers?

They basically build themselves up, level by level using its own hoisting power. At the top of the tower, there is a slewing unit which allows the crane to rotate using its gear and motor.

Assembling a Tower Crane

A tower crane is put together using another smaller crane, which usually require the team to hire a mobile crane in Sydney to complete the initial assembly of the jib and machinery. This is then built all the way up level by level and section by section using a climbing frame.
