Background technique

There is a risk of falling at the entrance and exit of the escalator, and accidents often occur. The most common accident is that children fall from the entrance and exit of the upper part of the escalator. There are also falling accidents caused by other passengers touching and leaning on the handrail in motion. An important reason for such accidents is that the fixed guardrails at the entrance and exit of the escalator are not standardized, and the distance from the handrail of the escalator exceeds the standard requirements, which makes it easy for passengers, especially children without parental supervision, to pass through the gap between the guardrail and the escalator. Another important cause of this type of accident is that the height of the guardrail is too low, and when passengers touch and lean on the handrail, they will fall as the downward running handrail falls.

In order to reduce the risk of falling at the entrance and exit of the escalator, the fixed barrier needs to be increased at least 100mm above the handrail, and it should be located between 80mm and 120mm from the outer edge of the handrail, and the maximum distance from the wall panel should not be greater than 120mm. These distances need to be measured and confirmed by escalator construction personnel when installing and when inspectors are inspecting and testing. However, because the measurement tools are relatively simple, and it is difficult to directly measure the fixed guardrail at least to the distance above the handrail belt, resulting in low measurement accuracy, and many people even directly observe and confirm with the naked eye because of the cumbersome measurement steps, there is a problem big security risk.
