The growth in building work in port installations at both a regional and national level has motivated the need, on the part of the successful contractors, to develop diverse mechanical devices for a variety of tasks involving the handling of large loads.

In the case of this grip, it was possible by means of simulation techniques that faithfully reproduced its in-service behaviour to obtain a highly optimized design in terms of weight that was not only appropriate for its purpose, the recovery of concrete blocks in breakwaters in the process of being dismantled for their reuse (15-50 Tm), but also drastically reduced operating costs (mainly associated with the cost of the crane) during the recovery process. On the other hand, the good behaviour demonstrated by the design that was finally adopted motivated its protection by a patent (utility model).
