To provide a work machine in which traveling devices and an implement device can be operated by common operating levers, wherein switching operation is easy and a changeover is easily confirmed. Inside a cab of the work machine, there are provided travel pedals, with which the traveling devices can be operated, and operating levers, with which the traveling devices and the implement device can be operated. A changeover switch is provided on a console positioned in the vicinity of one side of an operating sheet. The changeover switch switches over between a traveling mode, in which traveling operation is possible by the operating levers, and a work mode, in which implement operation is possible by the operating levers. The work machine has a controller which makes it possible to work by the operating levers when the travel pedal is not stepped on in the case where the work mode or traveling mode is selected by the changeover switch, and makes it possible to travel by the operating levers only when the travel pedal is stepped on in the case where the traveling mode is selected by the changeover switch.
1. A work machine having traveling devices and an implement device, the machine comprising:
travel pedals with which the traveling devices can be operated;
operating levers which are provided separately from the travel pedals, and with which the traveling devices can be operated and the implement device can be operated;
a changeover switch for making a changeover between a traveling mode, in which traveling operation is possible by the operating levers, and a work mode, in which implement operation is possible by the operating levers; and
a controller for making it possible to work by the operating levers when the travel pedal is not operated in the case where the work mode or traveling mode is selected by the changeover switch, and making it possible to travel by the operating levers only when the travel pedal is operated in the case where the traveling mode is selected by the changeover switch.
2. The work machine according to claim 1 comprising a travel alarm which operates by stepping on the travel pedal in the case where the traveling mode is selected by the changeover switch.
3. The work machine according to claim 1 , comprising a warning alarm which operates by releasing the travel pedal during the traveling operation by the operating levers,
wherein the controller makes the warning alarm operate and stops the traveling devices and the implement device when the work mode is selected by the changeover switch during the traveling operation by the operating levers or when traveling mode is selected by the changeover switch during the implement operation by the operating levers,
and releases the warning alarm by stopping operation of the travel pedals and the operating levers for a predetermined time.
