<P>PROBLEM TO BE SOLVED: To provide a fuel consumption display device for a crane which displays a track record in fuel consumption while the crane is travelling. <P>SOLUTION: The present invention comprises: idle time fuel consumption calculation means 13 to calculate fuel consumption while idling by accumulating fuel consumption during a period when a crane is in an idle state; travel time fuel consumption calculation means 14 to calculate the fuel consumption while traveling by accumulating the fuel consumption during the period when the crane is not in the idle state; average fuel efficiency calculation means 15 to calculate an average of the fuel efficiency; a fuel efficiency table 20; and a monitor 30 to display track records of the fuel consumption while idling, the fuel consumption while travelling and the average fuel efficiency. Thus, the invention enables an operator to know whether or not the operator is driving the crane with good fuel efficiency by comparing the same with past fuel efficiency and thereby encouraging the operator to reduce the fuel consumption in driving and operating the crane. <P>COPYRIGHT: (C)2012,JPO&INPIT |
