Electric lifting cage with safety device

The utility model discloses an electric lifting cage with a safety device. The electric lifting cage comprises two lifting-cage vertical columns which are arranged in a side-by-side manner, wherein the upper ends of the two lifting-cage vertical columns are connected with a cross beam; a lifting cage capable of moving up and down is arranged between the two lifting-cage vertical columns; the middle position of one lifting-cage vertical column is provided with the safety device for preventing the lifting cage from slipping; when the lifting cage is in a stopped state, a motor lead of an electric block is in a power-off state, an electromagnet is also in a power-off state, so that the magnetic force can not be generated. Due to the action of a return spring, a safety inserting pin extends out an inserting pin sleeve to block the lifting cage. The electric lifting cage disclosed by the utility model has the advantages that the lifting cage can play an effective role in safety protection when a platform is stopped, or steel wire ropes are broken and the braking of the electric block fails.
