What This Guide Helps With
Lift not moving, slow movement, or abnormal noise due to power, control, or drive-related external issues affecting motor operation.
Step-by-Step Troubleshooting
Ensure Patient Safety First
- Remove the lift from active patient use before troubleshooting.
- Expected: Patient safely transferred to another device.
Verify the Reported Issue
- Operate the lift (raise/lower and traverse if applicable) using the hand control.
- Expected: No movement, slow movement, or abnormal sounds (grinding, clicking).
- Why it matters: Confirms a true drive issue vs user operation error.
Check Emergency Stop (E-Stop)
- Ensure the E-stop is not engaged. Reset if necessary.
- Expected: Full system power restored and controls responsive.
- Why it matters: E-stop disables all powered movement including the motor.
If function returns → stop troubleshooting.
Verify Battery Charge and Seating
- Check battery level and confirm it is fully seated. Swap with a known good battery if available.
- Expected: Adequate charge and stable power.
- Why it matters: Low voltage can mimic motor failure or cause weak/erratic movement.
If operation returns → stop troubleshooting.
Observe for Overload Condition
- Ensure the lift is not exceeding its rated capacity and the sling is properly applied.
- Expected: Load within safe limits and evenly distributed.
- Why it matters: Overload protection can prevent motor operation or cause stalling.
If corrected and lift operates → stop troubleshooting.
Inspect Track and Travel Path (if applicable)
- Check for obstructions, debris, or physical resistance along the track. Manually move unit slightly if safe.
- Expected: Smooth, unobstructed travel path.
- Why it matters: Mechanical resistance can strain or stop the drive motor.
If obstruction removed and movement returns → stop troubleshooting.
Listen for Motor Activity
- Operate the lift and listen closely for motor noise.
- Expected:
- No sound → possible power/control issue
- Humming/clicking → motor attempting to run but unable to move
- Why it matters: Helps distinguish between electrical control vs mechanical drive issue.
Inspect Hand Control / Control Input
- Test all functions on the hand control. If available, try an alternate control.
- Expected: Consistent response across commands.
- Why it matters: Faulty control input can appear as motor failure.
If control issue found and resolved → stop troubleshooting.
Check for Visible Mechanical Issues
- Inspect drive unit area for signs of damage, unusual noise source, or misalignment (without disassembly).
- Expected: No visible damage, abnormal vibration, or loose components.
- Why it matters: External mechanical faults can prevent proper motor operation.
If the Problem Persists
All common external causes have been ruled out. The issue is likely internal to the motor, gearbox, or drive electronics.
Remove the lift from service
Label Out of Service
Send for repair or bench evaluation
Knowing when to stop prevents unnecessary risk and ensures safe equipment handling.
Clinical Use Tip
Never troubleshoot a lift while supporting a patient. Always transfer the patient first to prevent injury if the lift suddenly fails or moves unexpectedly.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Lift would not move along track and made clicking noise during operation."
Cause
What was observed during troubleshooting.
Example:
"Motor/drive unit failure after external checks (battery, control, and track) were verified functional."
Resolution
What action was taken.
Example:
"Removed lift from service and sent to vendor for drive unit repair."
Helpful Details to Include (If Known)
- Battery swapped and tested
- E-stop status verified
- Hand control tested
- Track obstruction checked
- Motor noise observed (none / clicking / humming)
- Load condition verified
- Final device status (removed from service)
Final Thought
Motor-related issues can appear complex, but many are caused by simple external factors like low battery, overload, or obstruction. A structured approach ensures patient safety and prevents unnecessary teardown. Recognizing when the issue is internal is key to proper escalation and reliable documentation.
That is successful troubleshooting.
