Abstract

PURPOSE: To simplify the configuration and operations of a control circuit for a hydraulically operated elevator by effectively connecting an electromagnetic switch of an electric motor for driving a hydraulic pump to an indicating switch of a direction control valve.
CONSTITUTION: An electromagnetic switch 22 of an electric motor 1 for driving a hydraulic pump 2 and an indicating switch 17 of a direction control valve 8 are effectively interconnected to each other by a diode 24 and so on. By this construction, two control circuits can be controlled to be switched by a common switch circuit. Accordingly, the configuration and operations of the control circuits can be simplified thereby.
