Abstract

PURPOSE: To secure a desired speed by providing a raising/lowering signal correction section for outputting a solenoid driving signal having a valve flow rate and pump volume efficiency compensated for based on a temperature signal from an oil temperature detecting means to an opening degree instructing means. CONSTITUTION: Upon receiving a raising/lowering command signal through an interface 28, an opening degree instructing means 23 outputs a solenoid driving current Iu or Id through a voltage current converter 29 to a raising/ lowering solenoid proportional pilot valve according to a specified pattern, and operates an actuator through a raising/lowering control valve. In this case, based on a detected oil temperature by an oil temperature detecting means, a raising signal correction section 26 outputs a solenoid driving signal having a valve flow rate at the time of car rising and the volume efficiency of a hydraulic pump compensated for, and a lowering signal correction section 27 outputs a solenoid driving signal compensated for at the time of car lowering. Thus, a desired acceleration/deceleration is always provided to the car, and high-speed/ low-speed running is performed.
