Abstract:
1. A display device for a work vehicle having a work apparatus operated by an actuator, the device comprising: a flow rate limit setting unit for variably setting a maximum flow rate level of hydraulic oil supplied to and drained from the actuator by operating an operating member; and a display unit for displaying the maximum flow rate level of the hydraulic oil supplied to and drained from the actuator, the display unit having a first display mode; wherein the hydraulic oil whose flow rate corresponds to a manipulated variable of the operating member is supplied to and drained from the actuator within a range defined by the maximum flow rate level that is set by the flow rate limit setting unit to cause the work apparatus to operate; a plurality of operating members, the maximum flow rate levels being able to be independently set by the flow rate limit setting unit for each of the operating members; and when the display unit is in the first display mode, a plurality of operating member symbols for indicating the operating members is displayed in the display unit, with the maximum flow rate levels of the hydraulic oil supplied to and drained from the actuator by operating each operating member being displayed in the display unit with the operating member symbols corresponding to each of the operating members, wherein the display unit includes a first section for displaying the maximum flow rate level for a first operating member and a second section for displaying the maximum flow rate level for a second operating member, the first operating member having a first operating member symbol, the second operating member having a second operating member symbol, the first section of the display unit positioned adjacent to the first operating member symbol to correlate the maximum flow rate level displayed in the first section with the first operating member, the second section of the display unit positioned adjacent to the second operating member symbol to correlate the maximum flow rate level displayed in the second section with the second operating member.
