摘要： A multi-functional lifting device, comprising a lifting device body; a power source; an electromagnetic DC motor; a decelerator connected to the DC motor; a main moving wheel positioned on an output axle of the decelerator; a rope element twined into the main moving wheel; a resilient wheel brake unit on one side of the main moving wheel locking the rope element into position; an intermediate wheel having a rope groove complementary to the rope groove of the main moving wheel; and a speed control module and a PCB board connected to the DC motor. The multi-functional lifting device is capable of providing controllable upward and downward movement when the power to the DC motor is connected or disconnected to the power source.
