1. A fuel consumption display apparatus for a crane, which is selectably in an operational state or in a standby state during operable mode in which an operation can be performed using the crane, the fuel consumption display apparatus comprising:
a standby accumulated fuel consumption calculator, which calculates standby accumulated fuel consumption by accumulating fuel consumption in the standby state during the crane operable mode, a standby duration calculator, which calculates standby duration in the standby state during the crane operable mode; an instantaneous fuel consumption calculator, which calculates instantaneous fuel consumption in the operational state during the crane operable mode; an average fuel consumption calculator, which calculates average fuel consumption in the operational state during the crane operable mode; a standby state determining device, which determines whether or not the crane is in the standby state during the crane operable mode; a monitor having a monitor controller, for displaying the standby accumulated fuel consumption, the standby duration, the instantaneous fuel consumption, and the average fuel consumption; and wherein the monitor controller performs control to display the instantaneous fuel consumption and the average fuel consumption on the monitor as long as the standby state determining device determines the crane not to be in the standby state and to display the standby accumulated fuel consumption and the standby duration on the monitor as long as the standby state determining device determines the crane to be in the standby state, and to display the standby accumulated fuel consumption and the standby duration on the monitor after a predetermined period of time has elapsed since the standby state determining device determines the crane to be in the standby state. |
