Furthermore, the maximum allowable load, allowable external load, and allowable screw shaft rotation speed of the screw jack must be verified. Exceeding these specifications will severely damage the entire lifting equipment. For worm gear screw jacks, whether under static, dynamic, or impact loads, the maximum allowable load must not be exceeded. A jack with sufficient capacity must be selected based on a safety factor, operating stroke, and screw stability calibration. During operation, the surface temperature of the screw jack's reduction gear should be controlled within the range of -15\u00b0C to 80\u00b0C, ensuring the surface temperature of the moving nut also falls within this range. The load capacity of the screw jack must be considered. When selecting a screw jack, the maximum allowable load must not be exceeded under static, dynamic, or impact loads.
