操作回路。 A phase control circuit that controls the phase of an AC power supply, a DC motor for driving an electric chain block connected to the phase control circuit via a full-wave rectifier, and the DC motor is operated at a low speed with the first press, and the second press is applied. The push button switch for hoisting and hoisting operates at high speed when pressed, and the second press of the push button switch for hoisting and hoisting causes O.
An operating circuit for an electric chain block that has one contact that turns FF and a variable resistor that is turned off so that the time constant of the phase control circuit is switched from the low speed of the DC motor to the high speed at the contact.
