ーンブロツク。 In an electric chain block that is equipped with a DC motor and is configured to rotate a load sheave using the driving force of the DC motor, a phase control circuit that includes a triax and a trigger element for controlling the triax is used to control the AC power from the AC power supply. The output of the phase control circuit is full-wave rectified by a full-wave rectifier circuit and supplied to the DC motor, and the hoisting and lowering speed of the electric chain block is changed from high speed to low speed or from low speed to high speed. and a speed control means that controls the triact via the bidirectional trigger diode and controls the speed in a high speed range or a low speed range steplessly or in multiple stages according to the switching of the switching means. An electric chain block characterized in that it is equipped with an operation circuit for controlling the electric chain.
