Abstract

PURPOSE:To obtain an excellent operability by allowing operator's intention and the driving mode of a working machine member to always coincide with each other. CONSTITUTION:Relations shown in the figure are preliminarily set by the setting means of a controller 20, and one of these relations is selected by a selecting switch 21 in accordance with the classification of work. Since the valve moving speed is in a range (c) and is gently changed till arrival of the lever speed at a prescribed speed A and is in a range (d) and is quickly changed thereafter as shown in the figure, operator's intention and the valve moving speed, namely, driving modes of an actuator and the working machine member coincide with each other. Thus, an excellent operability is obtained.
