Identifying and troubleshooting lift issues is crucial for maintaining the safety and convenience of elevator users. Proactive maintenance and troubleshooting not only prevent potential accidents but also minimise disruptions and costly repairs. In this article, we will explore common lift issues, step-by-step troubleshooting techniques, DIY tips for minor issues, preventive measures to minimise future problems, and the overall significance of addressing lift issues promptly.

Top 6 most common lift issues

Lifts may experience various issues that can disrupt their normal operation. Understanding these common issues is essential for effective troubleshooting. Some of the typical lift issues include:

  1. Stuck or unresponsive lift
  2. Slow or jerky movements
  3. Strange noises or vibrations
  4. Doors not closing or opening properly
  5. Irregular leveling with the floor
  6. Oil contamination

Stuck or unresponsive lift

  • Cause: This issue can occur due to a power outage, malfunctioning control system, or mechanical failure.
  • Solution: In the event of a power outage, ensure that the power supply is restored. If the lift remains unresponsive, check the control panel for any error codes or indicators of a specific issue.

Slow or jerky movements

  • Cause: Slow or jerky movements can be attributed to factors like improper lubrication, worn-out components, misaligned pulleys, or problems with the motor or drive system.
  • Solution: Regularly lubricate the moving parts as per the manufacturer’s guidelines. If the issue persists, it may require a more thorough inspection to identify and address the specific cause, which may involve replacing worn-out components, realigning pulleys, or repairing the motor or drive system.

Strange noises or vibrations

  • Cause: Unusual noises or vibrations can result from loose or worn-out parts, misaligned components, damaged bearings, or faulty control systems.
  • Solution: Inspect the lift for any loose or damaged parts, such as brackets, bolts, or screws, and tighten or replace them as necessary. Additionally, lubricate moving parts to reduce friction. If the noises or vibrations persist, conduct a thorough assessment and carry out any required repairs or replacements.

Doors not closing or opening properly

  • Cause: This issue can stem from various factors, including misaligned door tracks, faulty door sensors, worn-out door rollers, or problems with the door operator system.
  • Solution: Inspect the door tracks for any obstructions or misalignments, and clear or realign them accordingly. Clean the door sensors to ensure proper functioning. If the issue persists, an assessment should be run to repair or replace any faulty door components, or adjust the door operator system.

Irregular leveling with the floor

  • Cause: Irregular leveling can occur due to problems with the leveling sensors, misaligned guide rails, worn-out suspension ropes, or uneven floor surfaces.
  • Solution: Inspect the leveling sensors for proper alignment and cleanliness. Ensure that the guide rails are free from obstructions and properly aligned. If the issue persists, the suspension ropes should be examined and adjusted or replaced as needed. In some cases, adjustments to the lift controller may be necessary to ensure accurate leveling.

Oil contamination

  • Cause: Oil contamination can happen when hydraulic fluid or lubricating oil leaks into areas where it shouldn’t be, such as the lift shaft, pit, or control panel. It can occur due to damaged seals, faulty valves, or deteriorated hoses.
  • Solution: Identify the source of the oil leak and repair or replace the damaged components. Clean the affected areas thoroughly to remove any spilled oil. Regularly inspect and maintain the hydraulic system to prevent future leaks. Ensure proper disposal of any contaminated oil in accordance with environmental regulations.

Please note 📝 In the UK, lifts are required to be fitted with emergency communication devices. EN81-1 and EN81-2 offer assistance on installing a communication line to allow a trapped passenger to call for help in the event of a power cut.

Troubleshooting steps

When faced with a lift issue, following a systematic troubleshooting approach can help identify and resolve the problem. The following steps provide a framework for effective troubleshooting:

  1. Step 1: Safety first — Ensure the lift is secure and properly isolated before conducting any troubleshooting steps.
  2. Step 2: Identifying the issue — Observe symptoms and indicators, such as error messages, unusual sounds, or error codes on the control panel.
  3. Step 3: Basic checks — Verify the power supply, check the control panel for any malfunctions, and ensure the emergency stop is not engaged.
  4. Step 4: Inspecting door mechanisms and sensors — Examine the door mechanisms, including sensors, rollers, and tracks, to identify any obstructions or faulty components.
  5. Step 5: Examining the mechanical and electrical systems — Inspect the lift’s mechanical and electrical components, such as pulleys, cables, motor, and brake systems, for any signs of wear or damage.
  6. Step 6: Testing safety features and emergency procedures — Conduct tests on safety features, such as emergency brakes, overspeed governors, and emergency communication systems, to ensure they are functioning correctly.

DIY Troubleshooting Tips

For minor lift issues, there are several troubleshooting tips you can try:

  1. Resetting the system — Power off and restart the lift to resolve temporary glitches.
  2. Cleaning sensors and contacts — Dust or debris on sensors and contacts can cause malfunctions, so clean them regularly to ensure proper functioning.
  3. Lubricating moving parts — Apply lubrication to moving parts to reduce friction and ensure smooth operation.
  4. Adjusting door mechanisms — If doors are not opening or closing properly, adjusting the door mechanisms may solve the issue.

Preventive measures to avoid lift issues

To minimise future lift issues, proactive measures should be taken:

  1. Implement a scheduled maintenance program and conduct regular maintenance checks — Implement a scheduled maintenance program to identify and address potential issues before they escalate.
  2. Educating users — Provide clear instructions and guidelines on safe and proper usage to prevent misuse or damage to the lift.
  3. Monitoring and addressing recurring problemsKeep track of any recurring lift issues and take proactive steps to resolve them to prevent frequent disruptions.

Troubleshooting lift issues is vital for maintaining the safety and convenience of elevator users. Promptly addressing lift issues not only enhances safety but also minimises disruptions and costly repairs, ultimately benefiting both building occupants and facility managers. Proactive maintenance and troubleshooting are key to a reliable and efficient lift system.
