A Question of Classification
My crane must be a high-performance machine with high lifting capacities – a frequent customer request. Yet what use is having a powerful crane if the crane lands on the scrap heap after just a few years?
It is precisely when a crane is in constant use, e.g. performing intensive container or professional continuous-duty bulk handling up to 7,000 operating hours a year, that a completely different factor becomes a central consideration: the lifetime of the crane.
And this factor is linked inextricably to the classification – i.e. the choice of mechanical components and steel construction, the design and overall construction of the crane.
This interdependence has always been an issue which Gottwald has consistently dealt with in a frank and transparent manner and which formed a key part of development work for the Generation 5 cranes.
Basically, it is a question of the intensity of crane operation, on the one hand, and the associated degree of actual strain. On the other hand, there is the loading capacity of a crane, which increases as the wall thickness of the sheet metal and tubes used increases.
Put simply: the anticipated number of work cycles and, consequently, the service life of the crane are derived from the type of load and the designed loading capacity.
We encourage customers to consult Gottwald so that their crane can be precisely configured with them to meet their respective requirements.
