Do you have a construction project where you will be lifting heavy objects? You need a crane to do the job. Unless you have a construction company and you will be putting up many buildings, it would be absurd to buy a construction crane.
The practical way of going about it is to rent a crane from crane rentals. To rent the right machine, you need to consider plenty of factors that include:
Weight and size of the load
First, find out the weight and size of the load you are looking to lift and move. From the information collected, choose a crane that will effectively lift your desired load. Finding the right load size will also help you find the right rigging accessories such as shackles, slings, hooks, and ropes.
When renting the crane, you will see load charts with load capacity features of the crane. You should note that the rated capacity mentioned in the charts is the total gross weight that the crane can lift.
To find the actual load-bearing capacity of the crane, you need to deduct the weight of the rigging accessories from the gross weight.
While at it, pay attention to the type of load you are lifting. If lifting loads of an odd shape, you will need special rigging equipment and skilled riggers to execute it. To avoid accidents, it’s wise you have a specialist or consultant help you out.
HEIGHT AND HORIZONTAL DISTANCE REQUIREMENTS
If having a multi-storied project, you need to think about the lift weight of the crane. Of course, this will depend on how high you need to lift the load.
You will find the boom length and capacity details in the load charts. Boom is the inclined strut or spar supporting the tackle. The angle of the boom and its radius, along with the load weight and resting support play a critical role in keeping the crane stable.
Other than the vertical movement, you will also need to move the heavy equipment and material horizontally. So you will need to know the horizontal distance the boom can cover.
Different types of cranes have different boom lengths hence different lift heights and reach different radiuses.
You need to take your time and choose the right type of crane with the ideal boom length.
ON-SITE CONDITIONS AND ACCESS
Different cranes are ideal for various projects and have their pros and cons. For example, lattice boom crawler cranes feature the largest load-bearing capacity, but you have to transport and assemble them on the site.
This makes them an ideal choice when having long term projects requiring extreme lift heights and load reach.
You also need to transport tower cranes (the tallest cranes) to the worksite, and you can use them even in tightly confined areas, but you will need to have proper road access to the construction site as you have to use mobile cranes to assemble the tower crane.
If you have small and easily accessible construction projects, you will need to use HTCs that you can operate with a small team of two men. The cranes are also street legal hence you can easily drive them to your site and even use them for small-sized lifting projects.
The last thing to think about is the rental company you are renting the crane from. As a rule of thumb, it should be reputable and stocking high quality, properly maintained cranes. It’s always recommended you avoid renting from the first company you come across.
Take time to research different companies and compare the types of cranes they have, rental costs, and services they provide.
Settle on a company providing high-quality services at the most competitive cost. While the price is essential, you should avoid a crane rental companies that is too cheap as it might not be insured, which puts you at great risk in the event an accident happens at the worksite.
You also need to think about the number of machines the company has. For a great experience, work with a company with many cranes. This way you are sure you will get a replacement in the event the machine you are working with breaks down.
