GB 16899—1997《自动扶梯和自动人行道的制造与安装安全规范》第10.1.1条规定:自动扶梯的倾斜角α不应超过30°,当提升高度不超过6m,额定速度不超过0.50m/s时,倾斜角α允许增至35°(见图1中的ω)。自动人行道的倾斜角不应超过12°。对于ω角是指“梯级、踏板或胶带运行方向与水平面构成的最大角度”。图1所示由扶梯梯级的运行轨迹知:当扶梯上行时梯级倾斜角由E点逐渐增大至A点,A点至B点的角度最大且基本不变,再由B点至F点又逐渐减小。即AB段为倾斜最大角度段。
GB 16899-1997 “Escalator and moving walkway manufacture and installation of safety norms” Article 10.1.1: escalator tilt angle α should not exceed 30 °, when the lifting height does not exceed 6m, the rated speed does not exceed 0.50m / s, the tilt angle α is allowed to increase to 35 ° (see ω in FIG. 1). The angle of inclination of the travelator should not exceed 12 °. For the ω angle is the “maximum angle of the rung, pedal or tape running direction and the horizontal plane ”. Figure 1 shows the running track of the escalator rung: When the escalator goes up, the gradient of the rung gradually increases from point E to point A, and the angle from point A to point B is the maximum and substantially unchanged. From point B to point F slowing shrieking. AB segment is the maximum angle of inclination.
