问题 问答题 简答题

请简述轿顶安全操作的注意事项?

答案

参考答案:

1、在电梯轿顶作业,需移动轿厢之前,检查现场每一个人和每一件物品是否有问题;

2、在电梯轿顶作业,需移动轿厢之前,应大声、清楚地告知现场的每一个人,并说明电梯将运行的方向。移动电梯轿厢之前,应得到现场所有人确认。

3、电梯在移动时,不得拥挤在轿厢顶部;应站立在靠近电梯轿厢的中心位置,除非作业任务要求你远离电梯轿厢中心。

4、当心电梯井道的障碍物。障碍物可能是静止物,譬如承接梁/托梁,也可能是移动的,譬如对重装置;

5、不得靠在或让任何东西靠在电梯轿厢顶部,或相邻井道;

6、不得将任何平台直立在电梯轿厢顶部和护栏的限制性区域,或任何电梯轿厢顶部构成部分;

7、停留在电梯轿厢中空部分时,应小心电梯轿厢隔壁或后面的对重装置运行空间部分;

8、如果可以选择,作业时应尽量从上往下,而不要从下往上进行。因为电梯上行时可能的危险比下行时的要大得多;

9、在电梯轿厢顶部作业时,应始终将电梯调到“检修”模式。严禁将电梯调为“自动”模式,否则电梯可能随时突然意外地运行;

10、设备开始操作之前,或设备停止运行的时间稍长时,应始终关闭电梯轿厢顶部控制台的安全开关。将电梯调为“手动”或“检修”控制模式时,并不一定就可以使正在自动运行的电梯停止,这种错误操作可能导致致命的后果;

11、决不可认为:关闭安全开关就隔离了你正在作业的项目的电路。安全开关设计的目的是制止电梯运行,而非隔离所有电路。接触之前应先测试。电路可能必须是在关闭机房主控断路器之后才被隔开;

12、确保所有现场人员都已经了解出入电梯轿厢顶部的正确方法。
