Crane hire means you don't have to take care of the costly business of maintaining, servicing, and repairing your lifting gear – not to mention buying the things in the first place.
Even a small mobile crane rental cannot cost a huge amount of money if you don't buy it- If you buy then it is likely that your business will require more than one kind of crane during its lifetime.
In which case, were you to buy rather than use crane hire, you would be looking at millions of pounds in outlay.
Crane hire companies to make their money back by hiring out their vehicles and operators. You couldn't do that – if you bought your own lifting gear it would struggle to pay for itself.
The construction industries in the USA have worked by segmenting themselves for years. As a result, it has developed many services that are of use not just to other building companies, but to businesses with little or no connection.
It is conceivable that you could wish to hire a mobile crane for a lift that has nothing to do with building – but you will still be able to use a company with a huge amount of experience in lifting building materials in some extremely tight spaces. With all construction-related occupations, experience is the key phrase.
Mobile crane hire allows you to purchase the experience that you need when making a complex lift in a small or unhelpful environment – another reason why you end up saving money when you hire.
