All construction projects, big or small, will need cranes to lift and transport materials. This is why cranes are considered essential in the construction and developmental industry to transfer materials safely and quickly from one area to another.
Construction worksites can become death traps without cranes, with some tasks deemed impossible for humans to carry out. While cranes help you with construction, the overall success depends on the size and kind of crane you choose.
There might also be chances where you need to hire multiple cranes for a single project depending on the work duration, project scale, and job complexity. Choosing the wrong crane size would not only stop the project indefinitely but also compromise the safety of the on-site workers.
The only way to avoid such unfavourable situations is to choose the right cranes for your project. To search for reputed crane rental companies, you can use the help of the internet and choose a local establishment with good reviews.
Before you hire a crane, there are some tips you must keep in mind to choose the right machine.
Tips To Select the Right Crane Size for Your Construction Project
Here are some useful tips to figure out what size crane is best suited for your job requirements.
Load Weight and Size
You first need the size and weight of the load the crane will be lighting or moving. This will determine the crane size and additional accessories you need, like ropes, hooks, slings, and shackles.
You can consult the crane load chart to know more about a crane’s load capacity and features. The power mentioned on the load chart is the total weight a crane can lift within a given radius or distance. Also, you must deduct the weight of the rigging accessories on the crane before calculating its actual gross weight.
Apart from these considerations, also consider the kind of load the crane will be lifting. For instance, if renting a crane to lift odd-shaped material, consider the additional rigging equipment required to fulfil the purpose. You might also consider hiring skilled operators adept at lifting and moving such loads.
It is best to contact a local heavy machinery hire company to consult a specialist before making the decision.
Determine the Lift Height:
The height of the construction area and lifting load are as important as the weight to determine the correct crane size for the work site. These two factors will determine the crane boom length you need to choose for the project.
Suppose the crane operates in an open space and needs to transport materials to a higher round. In that case, arrange for a large crane that has a lift with a long boom length. Surprisingly weather also plays an important role along with the lift height in determining the crane size.
If your construction site is particularly windy, ensure that you choose a crane with a stable lift boom. The higher the boom extends, the more the load will sway due to the wind.
Size of Your Construction Area:
The size of your worksite also plays a significant role in determining the size of crane you need to hire. For example, if you are working on an urban developmental project or a residential area, then the worksites are compact.
So, you will need to hire a smaller crane that can manoeuvre easily within small spaces without hindering the construction process or compromising the crew’s safety. Similarly, modern tower cranes are used for heavy-duty lifting for mega projects like high-rise buildings, bridges, dams, power generation plants, and much more.
Additional Factors For Determining Crane Size
These are the three essential tips that you must heed before selecting your crane size. Apart from these, here are some more factors you can consider before choosing the correct crane.
- If you are using a hook as an additional attachment, determine its height along with the lifting equipment.
- Confirm if the crane will be working around several obstructions at the job site
- Verify if the obstacles around the crane will interfere with the crane’s counterweight while swinging.
- Verify that the ground is stable enough to take the crane’s weight, especially for large cranes.
All the above factors are essential for selecting the right crane size to do a proper job. You can consult your local crane rental companies for guidance and take their help to choose the best machine that suits your requirements.
