What This Guide Helps With

Lift raising unevenly, stopping mid-motion, or not lifting due to actuator, control, or external connection issues.

Step-by-Step Troubleshooting

Ensure Patient Safety First

• Remove the lift from active patient use before troubleshooting.
• Expected: Patient safely transferred to another lift or surface.

Verify the Reported Issue

• Operate the lift using the handset and observe lifting motion.
• Expected: One side lifts unevenly, jerky motion, or no movement.
• Why it matters: Confirms true actuator-related behavior vs user setup issue.

Check Emergency Stop (E-Stop)

• Ensure the emergency stop button is not engaged. Reset if needed.
• Expected: Unit powers fully and responds to controls.
• Why it matters: Engaged E-stop disables actuator movement.
• If lift operates normally → stop troubleshooting.

Verify Battery Charge and Seating

• Check battery level and ensure it is fully seated in the lift. Swap with a known good battery if available.
• Expected: Adequate charge and solid battery connection.
• Why it matters: Low or unstable power can cause weak or uneven actuator movement.
• If lift operates normally → stop troubleshooting.

Inspect Handset and Control Functions

• Test all lift controls (UP/DOWN and any alternate control panel if available).
• Expected: Consistent response across all control inputs.
• Why it matters: A faulty handset can mimic actuator failure.
• If alternate controls work → replace handset.

Inspect Lift Arm and Mechanical Linkages

• Visually inspect the boom, spreader bar, and pivot points for binding, obstruction, or misalignment.
• Expected: Smooth, unobstructed movement with no physical resistance.
• Why it matters: Mechanical binding can cause uneven lifting or overload one actuator side.
• If obstruction is found and corrected → retest.

Check for Uneven Load or Sling Application

• Ensure the sling is properly attached and weight is evenly distributed.
• Expected: Balanced load with equal tension on both sides.
• Why it matters: Improper sling placement can mimic actuator imbalance.
• If corrected and lift operates normally → stop troubleshooting.

Listen for Actuator Operation

• During lift attempt, listen for actuator motor noise (grinding, clicking, or silence).
• Expected: Smooth motor sound during lifting.
• Why it matters:
• Noise with no movement → possible actuator failure or mechanical binding
• No sound → possible actuator or control failure

Inspect Actuator Cables and Connections

• Check visible actuator wiring and connectors for looseness or damage. Ensure all connections are fully seated.
• Expected: Secure, undamaged connections.
• Why it matters: Loose or damaged cables can prevent proper actuator function.
• If connection issue is corrected → retest.

If the Problem Persists

If all external causes have been ruled out, the issue is likely due to internal actuator failure or control system fault.

Remove the device from service, label it Out of Service, and send for repair or bench evaluation.

Knowing when to stop prevents unnecessary risk and ensures safe equipment use.

Clinical Use Tip

Never troubleshoot a patient lift while supporting a patient. Always transfer the patient first to prevent fall or injury risk.

Work Order Documentation (CCR Method)

CCR = Complaint, Cause, Resolution

Complaint

What was reported by the clinical staff.

Example:
"Lift reported raising unevenly and stopping mid-lift during patient transfer."

Cause

What was observed during troubleshooting.

Example:
"Failed actuator with inconsistent movement despite proper power, load balance, and connections."

Resolution

What action was taken.

Example:
"Removed lift from service and sent to vendor for actuator replacement."

Helpful Details to Include (If Known)

• Battery charge level verified
• Alternate battery tested
• Handset functionality checked
• Mechanical inspection performed (no binding)
• Load and sling placement verified
• Audible actuator behavior noted
• Final device status (Out of Service)

Final Thought

Effective troubleshooting starts with safety and simple external checks before assuming internal failure. Uneven lifting is often caused by setup or power issues, but recognizing true actuator failure and escalating appropriately protects both patients and staff. Clear documentation supports reliability and future service decisions.

That is successful troubleshooting.
