The invention discloses a heavy load type escalator stair with high safety and relates to the field related to heavy load escalators. The heavy load type escalator stair aims to solve the problems that in the prior art, different ring molds cannot be selected according to needs of different materials, and the service life of the ring molds is short. A device main body is provided with first groovesheets. Multiple first groove sheets are arranged. The multiple first groove sheets are arranged linearly with the radial side line of the device main body as a standard. The distance between every two adjacent first groove sheets is consistent. The first groove sheets and the device main body are connected through argon arc welding. Multiple second groove sheets are arranged on the sides of thegroove sheets. The multiple second groove sheets are arranged linearly with the radial side line of the device main body as a standard. The distance between every two adjacent groove sheets is consistent. The second groove sheets and the device main body are connected through argon arc welding. Pressure relief grooves are formed in the second groove sheets. Two pressure relief grooves formed.
