搭乘扶梯“左行右立”?广州地铁:不安全 不提倡

搭乘扶梯“左行右立”?广州地铁:不安全 不提倡

  广州不少市民已习惯“左行右立” 羊城晚报记者 汤铭明 摄

近日,广州地铁出于安全考虑不再提倡“左行右立”。广州地铁表示,“左行右立”使扶梯受力不均,致扶梯频现故障,加之在移动扶梯上走动不安全,建议乘客尽量不要行走。

“左行右立”导致梯级轻微倾斜

曾几何时,搭乘自动扶梯时,自动靠右站立,把左侧留给赶路的行人,是大家共同遵守的文明礼仪。然而据广州地铁介绍,对扶梯的维修保养盘点中发现,约95%的扶梯右侧梯级链明显比左侧的磨损严重,导致梯级轻微倾斜,梯级两侧挡板及梳齿板磨损加剧。

扶梯检修专业人员介绍,扶梯在设计时,虽然考虑到长时间承受不平衡压力的最大载荷能力,但“左行右立”确实会导致扶梯局部部件承受过多的疲劳冲击,缩短设备寿命,使得扶梯频现故障。

此外,权威部门发布的安全提示中,自动扶梯留出一侧通行并不科学,因为在扶梯上走动很不安全,建议乘客尽量不要行走,一级扶梯台阶最多站两个人。

广州地铁特别提醒,扶梯的梯级高度与楼梯的台阶高度是不一样的,扶梯的梯级高度为21厘米,高于公共场所楼梯要求的15厘米高度,人员在上面行走,容易踏空或被绊倒,而行走过程中也容易挤碰到扶梯上其他乘客导致意外发生。因此,从安全出行的角度出发,乘坐扶梯时,请握好扶手站稳,注意脚下安全。赶时间的乘客,从楼梯通行比较稳妥。
