How can we compare cranes performance? We talk you about the key points.


There are different factor to considere when buying a knuckle boom crane. If we take into account two of them, the efficiency and the lifetime (working cycles), there are three important aspects to talk about:


  • One of the main aspects when choosing a crane is its lifetime: the definition of this word is : the equipment period of use until this is obsolete and can only be sold as scrap, for its residual value. What is going to prove the longevity of a crane is the class in which it has been made. S1 or S2: S1 are cranes made for achieving 32.000 working cycles and S2 will achieve 64.000. Find here an equipment amortization example:

S2 equipment purchase: 110.000€
Lifetime: 20 años
Residual value 10.000€
Anual amortization: 5.000€

In this case we are talking about a robust crane which can work for 20 years with a daily sevice, maybe a Fassi medium/heavy range crane. 



Lets see another example with a less quality equipment, with a lower cost but also a lower lifetime, as happens with some Fassi competitors cranes.


S1 equipment purchase: 85.000€
Lifetime: 10 años
Residual value 5.000€
Anual amortization: 8.000€

It seems that the equipment is much more cheaper, but it is costing a 60% more each year. 



  • Another aspect to take into account is the crane load performance (tn/m). We will find this detail in the Fassi load chards, in a transparent and precice way, but this not always happens. 


  • And last but not least, is also very important to take into considerationis both the design and the crane dimensions: we have to value the crane arm's geometry because it affects directly into the crane load power and the total folded dimensions, which will affect the assembling space. 

We hope all this information will be helpful when chossing a crane. We are always available for helping you making the best choice.
