    Please select the appropriate speed ratio and the lift with sufficient margin of load according to the load capacity table.

    The temperature of the surface of the reducer and the surface of the lift nut should be controlled at -15℃~80℃ when the lift is in operation.

    The lift shall not run continuously, and the load moment rate (T%) of a single lift shall not exceed 20% when accounting for 30 minutes.
