Abstract

PURPOSE: To allow an operator to control an electric chain block with the sense of raising or lowering a heavy object by himself by operating a grip up or down, and controlling a high/low speed changeover switch and a speed adjustment knob. CONSTITUTION: A high/low speed changeover switch 14, a speed adjustment knob 15 for adjusting speeds continuously in a high-speed range, and a speed adjustment knob 16 for adjusting speeds continuously in a low-sped range are arranged on the front surface of the top of a cylinder 11. When the pushbutton of the high/low speed changeover switch 14 is pushed to high speed side H or low speed side L, its contacts 14a, 14b close to the H or L side, and at the same time a speed-adjustment variable resistor VRH or VRL for high or low speed is connected. Under this state, when a grip 12 is moved upward, the contact 19b of a limit switch 19 closes, and a dc motor 45 rotates in the normal direction. Then the speed of rotation is adjusted depending on whether the high/low speed changeover switch 14 is switched to the high or low speed.
