The invention relates to a fixed or movable closing device used at an opening of a building, a vehicle, a fence or a similar surrounding object, in particular to a lifting device and a lifting isolation protection system using the lifting device. The lifting device comprises a fixed column, a lifting column and a spring balancer, the lifting column is guided to ascend and descend on the fixed column within a set height range, and the spring balancer acts on the lifting column so as to apply balance force except upward lifting force to the lifting column. According to the lifting device, the spring balancer is introduced to the lifting device, the constant force output characteristic of the spring balancer is utilized, balance force except upward lifting force can be applied to the lifting column, the effect of loading the balance force to the lifting column is continuously achieved, impact generated when the lifting column stops can be reduced, the movement speed of the lifting column is increased, and the st
