What This Guide Helps With
Troubleshoot powered transport that will not engage, moves inconsistently, or pulls unevenly due to power, controls, brakes, floor conditions, or mechanical interference.
Step-by-Step Troubleshooting
1. Secure the Patient and Prevent Unintended Movement
Stop powered transport immediately if the bed moves unpredictably.
- Engage the brakes when stationary.
- Confirm the patient is safely positioned.
- Use an alternate approved transport method if powered transport cannot be trusted.
- Do not troubleshoot an unreliable transport system while moving a patient.
- Keep hands, feet, and equipment away from moving wheels and drive components.
Expected outcome: The bed is secured and powered transport can be evaluated safely without a patient.
2. Confirm the Transport Complaint
Determine whether powered transport fails to engage, disengages unexpectedly, or pulls to one side.
- Ask staff whether the problem occurred during startup or while moving.
- Identify the direction of uneven pulling.
- Record any warning indicators or messages.
- Determine whether the issue occurs on all floor surfaces or only in certain locations.
- Note whether the transport system makes unusual sounds.
Expected outcome: The specific transport malfunction and conditions are identified.
3. Verify Battery and Power Status
Powered transport may depend on the bed's available electrical power and battery condition.
- Check battery and charging indicators.
- Confirm that the bed receives AC power when connected.
- Inspect the power cord and plug.
- Verify that the bed has completed any required startup sequence.
- Check whether other battery-powered functions operate normally.
Do not attempt transport if battery condition or available power is uncertain.
Expected outcome: The bed has an appropriate power condition for the approved transport function.
4. Inspect Brake and Steer Conditions
Check the external brake and steering controls.
- Confirm the brakes release and engage normally.
- Verify the appropriate transport or steering position.
- Inspect accessible casters for visible damage.
- Check for wrapped linens, debris, or foreign material.
- Confirm that all wheels intended to roll can move freely.
Expected outcome: The braking and steering systems operate normally without mechanical interference.
5. Inspect the Powered Transport Controls
Examine the transport controls for damage or inconsistent operation.
- Check for sticking or damaged buttons, handles, or switches.
- Verify that required operating conditions are satisfied.
- Observe transport engagement indicators.
- Compare the control response with the expected operation described in the manufacturer documentation.
- Do not bypass safety switches or interlocks.
Expected outcome: The transport system responds correctly to the authorized controls.
6. Evaluate Floor and Environmental Conditions
Check the area where the problem occurred.
- Inspect for uneven flooring, thresholds, debris, or slippery surfaces.
- Confirm that the bed is not contacting nearby equipment.
- Check that attached accessories are not dragging.
- Verify that the bed is in the appropriate transport configuration.
- Move to a clear, level testing area when safe.
Expected outcome: No environmental condition interferes with transport movement.
7. Perform a Controlled Transport Test
With the bed unoccupied, follow the approved transport test procedure.
- Confirm adequate clearance.
- Engage powered transport using normal controls.
- Observe initial movement and directional stability.
- Check for uneven pulling, wheel dragging, vibration, or unusual noise.
- Stop immediately if the bed moves unexpectedly.
Expected outcome: Powered transport engages and moves predictably without directional instability.
8. Verify Transport Disengagement and Braking
After transport testing:
- Confirm that powered transport disengages correctly.
- Verify that the bed stops as expected.
- Engage the brakes.
- Check that the bed remains stationary.
- Complete required manufacturer transport and brake verification.
Expected outcome: Powered movement, disengagement, steering, and braking operate reliably.
Troubleshooting can stop after successful verification and documentation.
If the Problem Persists
If power, controls, brakes, casters, floor conditions, and external obstructions have been checked, common external causes have been ruled out.
Possible service-level categories include the transport drive, motor control, engagement mechanism, steering components, battery system, or associated sensing and wiring.
The bed should be:
- Removed from service and labeled Out of Service.
- Sent for qualified repair or bench evaluation.
- Evaluated using Hillrom service documentation and approved test equipment.
- Repaired or configured only by qualified personnel.
- Returned to service only after successful transport, directional control, disengagement, and brake testing.
Do not continue using powered transport when its behavior is unpredictable.
Clinical Use Tip
A powered transport malfunction can create a collision or uncontrolled movement hazard. Arrange an approved alternative before transporting a patient.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Transport staff reported that the Compella powered transport pulled toward the left during movement."
Cause
What was observed during troubleshooting.
Example:
"Clinical Engineering found debris wrapped around a left-side caster, restricting normal wheel rotation."
Resolution
What action was taken.
Example:
"Removed the debris and verified normal caster movement, straight transport travel, disengagement, and braking."
Helpful Details to Include (If Known)
- Failure to engage or uneven pulling
- Direction of pulling
- Battery and charging indicators
- Brake and steer positions
- Transport control response
- Caster condition
- Floor surface and location
- Unusual noise or vibration
- Unoccupied transport test results
- Final equipment status
Final Thought
Safe powered transport depends on reliable movement, steering, and braking. Check power, controls, wheels, and environmental conditions before assuming a drive failure. Remove unreliable equipment from service, verify corrective actions, and document the findings.
That is successful troubleshooting.
