The invention discloses an electric hoist for conveying copper strips. The electric hoist comprises a main machine. One end of the main machine is connected with a motor, and the other end of the main machine is connected with a controller used for controlling a load chain to rise and fall. A frequency converter is arranged inside the main machine. A main loop and a control loop are included inside the frequency converter. The main loop comprises a rectifying circuit, a capacitive circuit and an inverter circuit. A switching group is arranged inside the control loop. A chain bag is installed beneath the motor. A limit spring is installed below the load chain inside the chain bag. Through the electric hoist, the copper strips can be conveyed flexibly and conveniently; moreover, the functions of visual display, overload warning, power-off protection, using frequency accumulation and the like are achieved. The using convenience and safety performance of the electric chain hoist are improved, the electric hoist is visual and convenient to use, and the labor amount of workers is reduced while working efficiency is improved. Automatic performance is excellent, the design is novel, a good innovation scheme is realized, and the market promotion prospects are broad.
