Abstract
A heavy-duty dust extractor ( 100, 200, 300, 400, 500, 600 ) comprising a dust separator ( 110 ), wherein the heavy-duty dust extractor is arranged to be supported on a ground surface ( 101 ) by one or more support members ( 150, 160 ), where one or more load sensors ( 210, 220 ) are arranged in connection to the one or more support members ( 150, 160 ) to measure a load on the one or more support members ( 150, 160 ), the dust extractor comprising a control unit ( 170, 900 ) arranged to receive data indicative of the load measured by the one or more load sensors ( 210, 220 ), where the control unit ( 170, 900 ) comprises means for measuring time, where the control unit ( 170, 900 ) is arranged to determine a dust extraction rate ( 740 ) in terms of a weight of extracted dust per unit of time based on the received data, and to control an operation of the heavy-duty dust extractor based on the determined dust extraction rate.
