A winch safety control device for building construction is characterized by comprising a power source voltage stabilizing device, a reserve power source voltage stabilizing device, a processor and a signal input module. The power source voltage stabilizing device is connected between the signal input module and a current transducer; the reserve power source voltage stabilizing device is connected between a voltage set sampling circuit and a voltage transducer; and the processor is connected with the signal input module. The power source voltage stabilizing device comprises a filter and a rectifier, and a short-circuit protector is connected between an oscillator and a rectification output circuit. The winch safety control device has the advantages that consumed power and the size are reduced; and the voltage and the current are sampled at fixed points of a constant-current source and a constant-voltage source, and selected by a control system and a touch screen, so that the adjusting process is simplified, and operation is convenient and rapid.
