The most common piece of lifting equipment found on the construction sites is the construction tower crane. Due to its sizeable tower-like structure, the crane pivots around; it is known as the tower cranes. The jib is supported by the tower mast, which will help the cabling, trolley, and hooks that do the lifting. So, these are the specialized cranes offered by the tower crane companies Sydney.
Why Are Tower Cranes Used?
As they are efficient at lifting and moving heavy materials while having a relatively smaller footprint on-site, these tower cranes are used.
At lifting material and moving across longer distances, tower cranes are the excellent option that you have. Their reach allows them to have unencumbered access to the entire job site in a lot of locations.
The Different Types of Construction Tower Cranes?
You will soon realize that the tower cranes come in many different shapes and sizes when driving through. The following are the types of tower cranes that are available:
Hammerhead tower crane
The standard type of tower crane found on construction projects throughout the world is the hammerhead tower crane. This hammerhead tower crane is quite recognizable through its vertical mast with the horizontal jib supporting both the cab. By carrying the hook and the cable, a trolley runs through the mast horizontally.
Luffing Jib Tower Crane
Often known as the luffing or luffer crane being the other common type of construction tower crane, this crane is also known as the luffing or luffer crane. Due to its diagonal arm that will be extending out from the top of the mast at an angle, this crane is recognizable. The hook point here is located off the end of the job, unlike the hammerhead. While being combined with the luffing jib tower crane’s angled arm typically has a higher capacity than the hammerhead crane, this is the crane that counters weighs located closer to the tower here.
It is similar to their little brother as they are similar to the luffing jib type you can think of the Derrick cranes. As their size is typically designed to sit on rooftops or smaller spaces, these cranes are unique. Due to their outriggers, allowing them to sit on a surface, these cranes are unique.
Mast Type – Self Supporting Tower Cranes
The typical tower crane is used in the shorter structures where tower extensions are not required with a self-supporting mast type. With weight or reinforced concrete block, the self-supporting tower cranes are anchored at the base. To anchor the bottom to the bedrock, piles might be required.
Mast Type – Travelling Tower Crane
On the projects with a larger footprint needing the equipment to be relocated regularly for lifting, a traveling tower crane is often used. They are either track-mounted or rail-mounted when it comes to the traveling tower cranes. The crane can travel horizontally along a path with the help of the tracks or the rails.
During this traveling period, depends on the base or the track design loads that may or may not be carried. You will have to make sure that you leave a path clear enough and flat enough on a project site that will allow the crane to travel if using this type of crane. You can risk the crane from tipping over if the path is not entirely leveled and debris clear.
Mast Type – Self Climbing Tower Crane
One of the fascinating pieces of equipment found on a construction site is possible by the self-climbing tower cranes. With a typical self-supporting tower crane, a self-climbing tower crane will be starting its life. It is to a concrete reinforcing base that the tower crane is erected on.
It is to the existing structure is where the building extends vertically here. Increasing its height by inserting a piece of the tower within the existing tower and climbing upwards is when the building reaches a point where the crane will not clear the structure.
