werkwijze voor het regelen van de productie bij een baggerwerktuig

摘要

A method for controlling the production of a dredging apparatus such that the highest possible concentration of the mixture is obtained, by using for controlling the dredger, the difference between the forces occurring at the dredging implement and the forces occurring upon maximum concentration. The value of that maximum force, which depends on the dredging conditions, is continuously adapted to the ratio between the existing concentration and the existing loosening force in order to obtain an immediate response to changing conditions during dredging.
