Construction, transportation, and other industries employ several different types of cranes based on the tasks that need to be carried out. One of the common types of cranes out there for construction projects is tower cranes. These cranes come in various sub-types that can make it difficult to make the right decision. You should be reaching out crane services with a clear plan and goal about which crane to choose. So, we will discuss the different types of cranes along with tower cranes to help you differentiate and make the decision-making process easier.
Types Of Tower Cranes
Before we can go deep into discussing how to choose a tower crane, it is important that you are aware of the types first.
Hammerhead Cranes
Hammerhead cranes tend to be one of the biggest cranes out there. These cranes are identified by a jib that extends horizontally and comes with a cabin where the operator sits. The cabin is also where the jib and tower connect with each other. Hammerhead cranes are able to handle the loading and shifting of extremely heavy weights at huge heights.
These cranes are mostly used for building skyscrapers and other similar types of buildings. Hammerhead cranes are balanced by weights at each end which allows the crane to be stable while working with heavy weights. Plus, these cranes need to be assembled and disassembled each time they need to be transported to a different location.
Self-Erecting Tower Cranes
These types of tower cranes, unlike hammerhead cranes, do not need to be assembled and disassembled. This is the biggest advantage of these cranes as they significantly reduce the launch time and the project’s overall cost. Although self-erecting tower cranes do come or can be custom ordered to have an operator’s cabin, in most cases, these cranes are handled via remote by an operator on the ground.
These types of cranes are quite easy to transport as well. The reason is that they come with a pair of tires that allows the machine to be attached to a truck and carried away. This means these cranes can be transported to different locations on the same day.
Luffing Jib Tower Cranes
Luffing jib tower cranes may look similar to hammerhead cranes but offer an advantage hammerhead cranes do not. These cranes are made for areas where rotation and maneuverability are an issue at working sites. Urban areas can be too crowded for jib rotation and most tower cranes come with a horizontal jib that cannot be moved.
However, a luffing jib tower crane has a jib which can be maneuvered up and down. This results in decreasing the turning radius. You might have come across operators lifting people to certain heights using a luffing jib crane instead of an electric wagon because it can be lowered and raised. But since luffing jib tower cranes tend to be expensive, these cranes are only used for special tasks.
What Key Factors Need To Consider When Choosing A Crane?
Now that we have discussed the different types of cranes and you are clear about the differences, let’s now take a look at some important factors that need to be considered as well.
Project Requirements
When it comes to looking for the right tower crane to rent, the first thing you need to do is analyze and determine the project requirements. This is key to making an informed decision. You need to keep in mind that projects vary based on the requirements and needs.
You may think that two projects may be similar but it is minor details that matter and make a difference. The best way to determine project requirements is by consulting an expert and determining the weight and type of loads that need to be handled. Moreover, you should also communicate with rigging companies MD what you need so they can perform the job correctly.
Plus, the terrain, dimensions, and location of the project should also be considered. Since the working environment directly influences the performance of the cranes, it is important that the area or location be first prepared.
Load Capacity
The lifting capacity of tower cranes differs based on the task. You cannot expect a crane to lift loads that are heavier than it can handle. Such negligence has caused major accidents in the past and can lead to casualties in the form of deaths and permanent injuries.
This is why you need to find out the type and amount of weight the project requires you to handle. Once you have a proper estimate, you will be able to filter out and narrow down the options instead of wasting your time and effort going through every crane out there.
Maintenance Records
Regular maintenance is key to ensuring the cranes perform safely and without any casualties. Some states have strict regulations regarding crane maintenance. These cranes are required to be regularly checked in order to be termed fit for being transported or used for construction tasks.
This means these cranes are registered with the state and if the owners are found manipulating the records, it could lead to serious penalties or legal issues. This is why you should always opt for a crane that is properly and regularly maintained.
These cranes as compared to the rest can be a bit expensive but a lot safer. Do not fall for cheap quotes and poorly maintained cranes. You will be risking the lives of everyone at the construction site.
Safety And Security Features
Modern tower cranes are loaded with advanced safety and security features not just for attraction purposes but as a necessity. Construction sites and other areas where tower cranes perform can be complicated. To ensure the cranes are stable and secure, advanced features are included to ensure everything is safe and sound while the crane performs tasks.
Tower and all other cranes can vary in price based on these features as well. Some states require cranes to have the latest safety features to keep up with industrial regulations. So, you might as well consider them.
How To Handle Blindspots When Lifting?
Blindspots are not only an irritating issue but also a serious one. Although blindspots are inevitable, the operators should be extra careful about them and possess the experience to handle them. This is because tower cranes are not like any other and the distance between the cabin and the hook can be as long as 100 meters or more.
In most cases, the operators rely on the staff on the ground using handle signals but this form of communication is not always smooth and accurate. Modern tower cranes come with advanced cameras and other safety features to prevent mishaps from happening without the operator knowing about them.
This also reduces the need for ground staff. This means that while choosing a tower crane, you should consider such safety and security features that help the operator perform safe maneuvers.
Conclusion
Although the information mentioned above will help you make much better decisions, you should consult your team and also crane rentals DC. It is still easy to become lost in the numerous options so you should take your time and be patient with the process as it can be a bit overwhelming.
