How to install escalator newel chain

2024-11-25

The installation process of the escalator turnaround chain involves multiple steps and requires ensuring safety and accuracy. Below is an overview of the installation steps for the escalator turnaround chain:

1.Shut Down the Escalator:

Ensure the escalator is completely stopped and disconnect the power supply or use the corresponding circuit breaker to cut off the power, preventing accidents during the installation process.

2.Remove Old Components:

Dismantle the escalator's handrails and support structures (if necessary) to access the hand strap and turnaround chain.

Use appropriate tools to remove the connecting parts of the hand strap, such as bolts or clamps.

Detach the connection between the hand strap and the turnaround chain, typically requiring the removal of one end of the chain and then taking it off the sprocket of the escalator.

3.Prepare the New Turnaround Chain:

Ensure the new turnaround chain meets the specifications and requirements of the escalator.

Inspect the new turnaround chain for any damage or defects to ensure its good quality.

4.Install the New Turnaround Chain:

Place the new turnaround chain on the sprocket of the escalator and ensure the chain is correctly installed in the sprocket teeth.

Adjust the tension of the turnaround chain to ensure it can operate smoothly without causing excessive noise or wear.

5.Connect the Hand Strap:

Connect the new hand strap to the turnaround chain and securely fix it using connectors.

Ensure the connection between the hand strap and the turnaround chain is tight and reliable to prevent detachment or damage during operation.

6.Reinstall the Handrails and Support Structures:

Reinstall the handrails and support structures of the escalator back to their original positions.

Ensure they are securely fixed to prevent shaking or detachment during escalator operation.

7.Testing and Adjustment:

Reconnect the power supply and start the escalator.

Conduct necessary tests and adjustments to ensure the hand strap and turnaround chain are installed correctly and the escalator is operating normally.

Check the operation of the turnaround chain and hand strap to ensure there are no abnormal noises, wear, or looseness.

8.Safety Check and Confirmation:

Conduct a comprehensive safety check after the installation is completed.

Ensure all components are correctly installed and securely fixed.

Confirm that the escalator can operate smoothly and safely.

Please note that the installation of the escalator turnaround chain involves mechanical and electrical components, as well as personnel safety. Therefore, it is recommended to seek professional escalator maintenance services or technicians for installation. At the same time, during the installation process, be sure to comply with relevant safety regulations and operating procedures to ensure the safety and correctness of the work.
