<p>A device for selecting a control mode in a power construction vehicle having proportional control valves has a control mode select switch which selects a function for setting new matching relations between the control levers and the proportional control valves. A controller sets and stores the new matching relations, and controls the actuators in accordance with the new matching relations. In the control mode selection method, one operational motion of an actuator is primarily selected and displayed on a display means. Thereafter, a voltage signal indicative of a levering angle of a control lever associated with the selected actuator is output, thus setting a new matching relation between the control lever and an associated proportional control valve. The above process is repeated in order to continuously set and store new matching relations between the control levers and proportional control valves associated with the other actuators.</p> |
