Abstract

PURPOSE:To smoothly change a connecting attitude while altering speed of a working device, by regulating speed by the working device at two stages of high and low velocity by change in flow rate caused by opening and closing of a hydraulic circuit equipped with a second throttling part and maintaining flow of hydraulic oil in operation of speed alternation by a hydraulic circuit part equipped with a first throttling part. CONSTITUTION:When a hydraulic circuit part 33 equipped with a second throttling part is opened and closed and a hydraulic oil flows in large flow rate in both a hydraulic circuit part 32 equipped with a first throttling part and the hydraulic circuit part 33 equipped with a second throttling part, operation speed of actuator 1 becomes high. When the hydraulic oil flows in a small flow rate only in the hydraulic circuit part equipped with the first throttling part, operation speed of the actuator becomes low. The hydraulic oil continues flowing in the hydraulic circuit part equipped with the first throttling part during opening and closing operation of the hydraulic circuit part equipped with the second throttling part.
