What This Guide Helps With
Troubleshooting a stretcher that will not raise, lower, drifts, binds, or responds poorly to hydraulic lift controls.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Remove the stretcher from active patient use if height movement is unreliable, uneven, drifting, or difficult to control. Transfer the patient to another safe surface before troubleshooting whenever possible.
Expected outcome: The stretcher is safe to inspect without risk of patient movement, fall, or uncontrolled height change.
Verify the Reported Lift Problem
Attempt to raise and lower the stretcher using the normal hydraulic pedals or controls. Observe whether the issue is no lift, slow lift, uneven lift, drifting down, failure to lower, or binding during travel.
Expected outcome: The failure mode is clearly identified before parts or hydraulic failure are assumed.
If the stretcher operates normally during testing, document that the issue could not be duplicated and return it only after confirming safe function.
Check for Obvious Obstruction Around the Base and Lift Frame
Inspect underneath and around the stretcher for linens, cords, trash, equipment bags, foot pedals, transport straps, or other objects interfering with lift movement.
Expected outcome: Nothing is physically blocking the lift mechanism or pedal travel.
If an obstruction is found and removal restores normal lift function, stop and document the correction.
Inspect the Hydraulic Pedals or Lift Controls
Confirm the raise and lower pedals move freely and return to their normal position. Look for bent pedals, loose linkages, missing hardware, damage, or floor debris restricting movement.
Expected outcome: Controls move smoothly and fully engage the lift/lower function.
If a stuck or obstructed pedal is corrected and lift operation returns to normal, stop and document the repair.
Confirm the Stretcher Is Not Overloaded
Verify the stretcher is not being used beyond its rated capacity and that excess equipment, supplies, or accessories are not adding abnormal load.
Expected outcome: The hydraulic system is being tested under appropriate load conditions.
Why it matters: A weak or overloaded hydraulic system may raise slowly, fail to raise, or drift.
Check Caster Position and Floor Contact
Make sure all casters are properly contacting the floor and that the stretcher is on a level surface. Inspect for a caster or base issue that may make the frame appear uneven during height adjustment.
Expected outcome: The stretcher is stable and not falsely presenting as a lift issue because of caster, floor, or frame position.
Inspect for Visible Hydraulic Fluid Leakage
Look around the hydraulic pump, lift cylinder area, base frame, and floor beneath the stretcher for oil, wet residue, or fresh dripping. Do not continue cycling the lift if an active leak is present.
Expected outcome: No visible hydraulic fluid leakage is present.
If fluid leakage is found, remove the stretcher from service and send it for repair or bench evaluation.
Listen and Feel for Abnormal Pump Behavior
Operate the lift pedal and note whether the pump feels unusually soft, fails to build pressure, requires excessive strokes, or makes abnormal clicking, grinding, or squeaking sounds.
Expected outcome: The pump should build lift smoothly without excessive effort or abnormal noise.
Why it matters: Weak pump action can point to a hydraulic, linkage, or lift component issue that requires repair.
Check for Drifting After Raising
Raise the stretcher to a safe test height and observe whether it slowly lowers without the lower control being activated. Keep hands and feet clear of moving parts.
Expected outcome: The stretcher holds height without uncontrolled lowering.
If the stretcher drifts down, remove it from service because the lift system may not safely support patient use.
Check Lower Function Separately
If the stretcher raises but will not lower, inspect the lower pedal or release control for restricted movement, bent components, or linkage that does not appear to engage. Do not force the pedal.
Expected outcome: The lower control should release height smoothly and predictably.
If the stretcher remains stuck raised or lowers unpredictably, remove it from service.
Inspect for Frame Binding or Uneven Lift Movement
Watch both sides of the litter/frame while raising and lowering. Look for twisting, hesitation, scraping, loose hardware, damaged linkage, or anything that causes one side to move differently than the other.
Expected outcome: The lift moves evenly without binding, twisting, or abnormal resistance.
If binding or frame damage is present, stop troubleshooting and escalate for repair.
Perform a Final Functional Check Only If No Fault Is Found
Cycle the stretcher through several raise and lower movements without a patient on it. Confirm smooth movement, proper stopping, no drift, no leaks, and stable frame position.
Expected outcome: The stretcher raises, lowers, and holds height consistently.
If the function is reliable, return the stretcher to service and document the checks performed.
If the Problem Persists
If the hydraulic lift still will not raise or lower properly after external checks, common user-accessible causes have been ruled out. The problem is likely internal to the hydraulic pump, cylinder, release valve, linkage, or lift mechanism.
The stretcher should be:
- Removed from service
- Labeled Out of Service
- Sent for repair or bench evaluation
Knowing when to stop is proper troubleshooting. A stretcher with unreliable height movement, drifting, leakage, or binding should not remain available for patient use.
Clinical Use Tip
Do not troubleshoot lift movement while a patient is on the stretcher unless the situation is controlled and clinically safe. If the stretcher will not hold height, drifts, or lowers unpredictably, move the patient to another safe surface first. Maintain therapy continuity and patient safety before attempting equipment troubleshooting.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Staff reported the Hillrom P8000 Procedural Stretcher would not raise properly using the hydraulic lift pedal."
Cause
What was observed during troubleshooting.
Example:
"Found weak hydraulic lift response during testing with no external obstruction present and no safe reliable height hold."
Resolution
What action was taken.
Example:
"Removed stretcher from service, labeled Out of Service, and sent for bench evaluation of the hydraulic lift system."
Helpful Details to Include (If Known)
- Whether the stretcher would not raise, would not lower, drifted down, or moved unevenly
- Whether the issue occurred with or without patient load
- Pedal movement and pedal return condition
- Visible hydraulic fluid leakage
- Any unusual pump feel, noise, binding, or resistance
- Caster and floor condition during testing
- Whether lift frame movement was even on both sides
- Alarm behavior, if any display or staff-reported warning was involved
- Accessories swapped or removed during testing
- Power behavior, if any powered accessory or control was involved
- Environmental factors such as floor slope, debris, cords, linens, or transport conditions
- Indicator lights, if any powered accessory or status indicator was involved
- Final device status: returned to service or removed from service
Final Thought
Hydraulic lift problems on a stretcher should be approached carefully because they directly affect patient transfer safety, fall prevention, and caregiver control. Start with simple external checks, confirm the symptom, rule out obstruction or control issues, and escalate when the lift system is unreliable. Clear CCR documentation helps show what was checked, what was found, and why the stretcher was or was not safe for use.
That is successful troubleshooting.
