Abstract: PURPOSE: A hand rail driving system for passenger transportation equipment is provided to prevent generating slippery of hand rail and improve the driving force. CONSTITUTION: A hand rail driving system for passenger transportation equipment includes a frame(11), a balustrade(12), a hand rail(13), a driving pulley(14), pushing rollers(15,15'), guide rollers(16,16'). The guide rollers(16,16') are mounted to guide the hand rail(13) to the driving pulley(14), in the place on both side of the driving pulley(14). A V shaped rail insertion groove(14a) which has about 4-6mm smaller width of bottom(L') than the width(L) of the hand rail(13), is formed on outer side of the driving pulley(14). A rubber(17) is attached on inside of the V shaped rail insertion groove(14a). An assist guide roller(18,18') is installed on the both side of the guide roller(16,16').
