The velocity of a cage during a time interval from the start of deceleration to the stoppage of the cage is controlled by utilizing a velocity characteristic which changes depending upon the load condition or oil temperature of a hydraulic elevator, that is, a magnitude by which the velocity characteristic during the acceleration of the cage differs from a reference running characteristic. Thus, even when the load state or the oil temperature has changed, the operating period of time of the hydraulic elevator is shortened, so that a comfortable ride, energy saving, cost reduction etc. are attained. |
