ー操作の警報装置。[Scope of claim for utility model registration] (1) A hydraulic motor for traveling is arranged in the lower traveling body,
In addition, a shift lever device for changing the speed level of the vehicle is provided near the driver's seat of the upper revolving structure, and on the other hand, it is set to input switching operation signals from a mode selection switch and a brake operation switching switch to the controller, and the above switching operation In a wheeled excavator in which an output signal is output from the controller to the servo mechanism of the variable pump and the governor control device of the engine based on the signal, each contact point of the forward and reverse speed stages of the shift lever switch of the shift lever device described above. and a mode selection switch, so that an alarm is generated when the mode selection switch is operated to the work mode position and the shift lever switch is switched to either the forward or reverse speed position. A shift lever operated alarm device featuring: (2) Connecting a brake operation selector switch to the mode selection switch according to claim 1, operating the mode selector switch to the work mode position, and switching the brake operation selector switch to a position other than the work mode position;
An alarm device for shift lever operation, characterized in that the shift lever switch is configured to generate an alarm when the shift lever switch is switched to either forward or reverse speed position.
