Abstract

PURPOSE: To provide an apparatus for controlling speed of a hydraulic actuator for remote control, wherein the spool movement is adjusted by a sub-hydraulic actuator through changing the closing and opening periods of a switch, and therefore the speed of a main acutator can be easily controlled.
CONSTITUTION: A switch 29 is operated intermittently to desirably adjust the closed periods and opened periods of the switch 29. Thus a piston of a sub-hydraulic actuator 35 can be displaced from its neutral position to a certain right position or can be displaced to the neutral position, and thus the degree of opening if a valve groove of a spool of a change-over valve 31 can be freely changed to control the working speed of a main hydraulic actuator 27.
