How to change Escalator step?

The main function of escalator steps is to provide a riding platform and support the operation of the escalator. Specifically:

‌Provide a riding platform‌: The steps are where the passengers of the escalator stand, providing passengers with a reliable riding platform. The steps are spacious and comfortable, and passengers can avoid the discomfort of standing for a long time when riding the escalator. It is also convenient for passengers to discuss information and operate handheld items.

‌Support the escalator skeleton‌: As one of the important components of the escalator, the steps support the skeleton system of the escalator. The connecting parts between the steps accept the weight of the walking device and the chain, and play a role of connection and support, so that the escalator can run smoothly and maintain structural stability.

In addition, the steps can also improve the overall style and decorative effect of the escalator by changing the color, pattern and material.

‌The replacement of escalator steps needs to be carried out according to the following steps‌:

‌Preparation‌:

Stop the escalator and disconnect the power supply to ensure safe operation‌.

‌Removing damaged steps‌:

Open the lower cover of the escalator, take out the step protection plate (dustproof plate), and remove the lower comb plate‌.

Use a turntable or an inspection box to move the damaged steps to the loading and unloading port on the lower turning wall (step loading and unloading is generally carried out at the tensioning device)‌.

Loosen the step screws and slowly remove the damaged steps at the loading and unloading port‌.

‌Installing new steps‌:

The new steps are installed in the reverse process of the removal method, that is, the two bearing seats of the steps are pushed toward the step spindle sleeves, and the screws are tightened‌.

The newly installed steps must be aligned with the original steps above‌.

‌Inspection and debugging‌:

After installation, inspect the up and down operation of the escalator and check the operation of the steps in the entire ladder path‌.

When checking, pay attention to whether there is a constant gap between the step pedal teeth and the adjacent step pedal teeth to ensure the smoothness and safety of the escalator operation‌. By following the steps above, technicians can replace escalator steps safely and efficiently.
