CONSTRUCTION excavators in infrastructural works, in primary and secondary site demolition, and in quarry break-
ing.
CASE CONSTRUCTION defines application rules in order to match each breaker model with the most suitable con-
figuration of the machine, and to refer breaker application to specific working conditions.
