<p><P>PROBLEM TO BE SOLVED: To provide a clogging information system which can improve the durable hour of a filter. <P>SOLUTION: The clogging information system 20 of a hydraulic excavator is a pressure detection means 21 to detect the pressure of exhaust gas from an engine 15, and a clogging information means 22 to inform an operator of the clogging state of the filter 16 depending on the detected signal from the pressure detection means 21. The clogging information means 22 informs the operator by the output of an information portion 24 when judging that the detection pressure is not less than a first set pressure and less than a second set pressure, and informs the operator by the output of the information portion 24 and the output lowering control of the engine 15 when judging that the detection pressure is not less than the second set pressure. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
