徴とするリフタ用制御装置。 While balancing the weight of the lifting table and its overload by the force of the balance cylinder, the lifting table is moved up and down by the drive cylinder, and the speed of this drive cylinder is controlled by the speed control circuit, and the balance is In a lifter control device that accumulates equilibrium pressure set by a pressure regulating valve for setting equilibrium pressure in an accumulator connected to a cylinder, the lower limit holding pressure is used to set a lower limit holding pressure higher than the above equilibrium pressure. A control device for a lifter, characterized in that a setting pressure regulating valve is connected to the accumulator via a switching valve that opens when the elevating table reaches a lowering limit position.
