Occasion:

1. The steel wire passes through the surface of the handrail or sliding layer. This is the most dangerous situation when the handrail field fails, because it means that the steel wire in the handrail is likely to have broken.
2. The escalator handrail can be easily removed from the guide rail; this is a phenomenon that the edge of the escalator handrail becomes larger. According to reports, there have been two accidents in which the passenger’s finger was caught between his lips and the guide and was torn off as a result.
3. The handrail is lagging when the escalator is running. The speed of the handrails cannot be compared with the speed of the stairs. This will cause passengers to move up and down at different speeds when holding the armrests, especially for the elderly and weak passengers who are prone to fall.
4. The rupture of the compression line on the armrest usually does not cause harm to passengers, but the ruptured part may still pinch fingers, so there is a certain risk.
5. There are cracks on the edge of the handrail. Since passengers will hold the handrail tightly when moving on the escalator, even if the edge of the handrail is cracked, it is usually closed during this ride. In addition, the cracked edge of the handrail usually does not reach a position above the compression line of the handrail, as this usually does not cause passenger safety issues.
6. Small cracks on the surface of the handrail are usually caused by aging and cracking of the handrail. The cracks will not affect the safety of passengers. However, if left unattended for a long time, the small cracks will expand, and may even cause larger cracks, which will cause problems with the railing operation.
7. The bulge on the surface of the armrest is only caused by the layering of the material inside the armrest. The bulge usually does not cause a problem to the operation and safety of the armrest, but it cannot be ignored.
8. Small bubbles appear on the surface of the escalator handrail, because they are usually contaminated by oil, which will not affect the operation and safety of the handrail.

Please note:
When replacing the escalator handrails, stop the escalator first, turn off the power, install warning signs, and remove the tension connection screws to ensure personal safety.
