I. Introduction

Hydraulic home lifts play a significant role in providing convenient vertical access within residential properties. To maintain their optimal performance and ensure safety, a proper maintenance routine is essential. This guide details the step-by-step maintenance procedures and important aspects to consider for hydraulic home lifts.

II. Maintenance Schedule

It is recommended to carry out routine maintenance at least once a year. However, if the lift experiences heavy usage or operates in a harsh environment, more frequent inspections and servicing may be required.

III. Maintenance Steps and Details

  1. Exterior and Interior Visual Check
    A. Examine the lift car's interior and exterior surfaces for any scratches, dents, or signs of wear.

    B. Inspect the buttons, indicators, and communication systems inside the car to ensure they are in proper working order.

    C. Check the door panels, frames, and seals for any damage or misalignment that could affect the door's operation.
  2. Hydraulic System Maintenance
    • Regularly check the hydraulic fluid reservoir. The fluid level should be within the marked range. If it is low, add the appropriate type of hydraulic fluid as specified by the manufacturer.

    • Inspect the hydraulic hoses and fittings for any leaks, cracks, or signs of deterioration. Replace any damaged components immediately.

    • The hydraulic pump should be examined for proper operation. Listen for any unusual noises during its operation, which could indicate a problem with the pump. Check the pump's pressure settings and adjust if necessary according to the manufacturer's guidelines.

  3. Electrical System Inspection
    • Inspect the electrical control panel. Look for any loose wires, burned-out components, or signs of overheating.

    • Test the safety circuits, including the emergency stop button, door interlocks, and overload protection sensors. Ensure they function correctly and activate as expected.

    • Check the power supply and wiring connections to and from the lift. Make sure the connections are tight and free from corrosion.

  4. Guide Rail and Mechanical Component Check
    • Examine the guide rails for any signs of wear, such as grooves or burrs. Clean the rails if they are dirty or have debris on them.

    • Inspect the rollers and pulleys that run along the guide rails. Check for proper alignment and lubrication. Replace any worn-out rollers or pulleys.

    • The lift's suspension system and counterweights should also be inspected. Ensure the cables or chains are in good condition, without any fraying or stretching.

  5. Lubrication
    • Apply the recommended lubricant to the guide rails, rollers, pulleys, and other moving parts. Use the correct amount and type of lubricant to prevent over-lubrication or the use of incompatible substances that could damage the components.

    • Lubricate the door hinges and tracks to ensure smooth door operation.

  6. Functional Testing
    • Conduct a series of tests to check the lift's normal operation. This includes starting and stopping the lift at different floors, ensuring smooth acceleration and deceleration.

    • Test the emergency lowering function. Activate the emergency lowering mechanism and verify that the lift can descend safely and at a controlled speed to the nearest floor.

    • Check the leveling accuracy of the lift when it stops at each floor. The floor of the lift car should be level with the landing floor within a specified tolerance.

  7. Safety Device Verification
    • Inspect all safety devices thoroughly. This includes the overspeed governor, which should be tested to ensure it activates and stops the lift in case of excessive speed.

    • Check the buffer systems at the bottom and top of the lift shaft. Ensure they are in proper working order and can absorb the impact if the lift overtravels.

    • The emergency communication system, such as an intercom or emergency call button, should be tested to confirm it can effectively connect with the outside for assistance.

  8. Documentation and Record Keeping
    • Keep a detailed maintenance log. Record all maintenance activities, including the date, tasks performed, any parts replaced, and the condition of the lift before and after servicing.

    • Note any unusual observations or issues that were detected during the maintenance process. This information can be valuable for future reference and troubleshooting.


IV. Safety Precautions

  • Always disconnect the power supply to the lift before starting any maintenance work.

  • Use proper safety equipment, such as safety glasses, gloves, and work boots.

  • Only trained and authorized personnel should perform maintenance on the hydraulic home lift.

  • Follow the manufacturer's instructions and guidelines precisely during the maintenance process.
