What This Guide Helps With
Troubleshooting weak lift, height drift, visible hydraulic leaks, pump pedal issues, or stretcher not raising properly.
Step-by-Step Troubleshooting
Ensure Patient Safety First
Remove the patient from the stretcher if the height adjustment is unstable, drifting, leaking, or not lifting correctly.
Expected outcome: The stretcher is empty and safe to inspect.
Why it matters: A hydraulic failure can cause unexpected movement, creating a fall or transfer risk.
Verify the Reported Hydraulic Problem
Operate the lift pedal or pump mechanism with no patient load. Check whether the stretcher raises, lowers, drifts down, binds, or fails to move.
Expected outcome: The reported symptom is confirmed or cannot be duplicated.
If the stretcher operates normally, document findings and perform a functional check before returning to service.
Check for Visible Hydraulic Fluid Leaks
Inspect under the stretcher, around the pump, hydraulic cylinder, hose/fitting areas if visible, and the floor beneath the unit. Look for wetness, oily residue, or dripping fluid.
Expected outcome: No hydraulic fluid should be visible.
If fluid is leaking, stop troubleshooting, remove the stretcher from service, and send it for repair.
Inspect for External Obstructions or Binding
Check the lift linkage area, frame, pedals, and moving sections for trash, linen, straps, broken accessories, or damage interfering with movement.
Expected outcome: The lift mechanism moves freely without rubbing, binding, or obstruction.
If an obstruction is found and safely removed, retest the lift function. If resolved, stop.
Check Pump Pedal Movement
Press the hydraulic pump pedal through its normal travel. Confirm it is not loose, bent, jammed, disconnected, or contacting the frame incorrectly.
Expected outcome: The pedal should move smoothly and return properly.
If the pedal is physically damaged or does not engage the pump, remove the stretcher from service for repair.
Check Release Pedal or Lowering Control
Confirm the lowering/release pedal is not stuck partially engaged. A partially engaged release can cause the stretcher to drift down or fail to raise.
Expected outcome: The release control should return fully to the neutral position.
If freeing the control resolves the issue, perform several raise/lower cycles and stop if normal operation returns.
Test Lift Under No Load
Raise the stretcher from the lowest to highest position without a patient. Watch for weak pumping, slow rise, uneven movement, or drift after reaching height.
Expected outcome: The stretcher should raise smoothly and hold position.
If it lifts empty but feels weak, drifts, or requires excessive pumping, suspect hydraulic wear or internal leakage.
Check for Height Drift
Raise the stretcher to a mid or high position and let it sit unloaded for several minutes. Monitor whether it slowly lowers.
Expected outcome: The litter should hold height without noticeable drop.
If the stretcher drifts down, remove it from service for hydraulic evaluation.
Listen and Feel for Abnormal Operation
During pumping, listen for unusual clicking, grinding, air-like pumping feel, or lack of resistance. Also check for uneven lift action.
Expected outcome: Pumping should feel consistent and controlled.
If the pump feels soft, inconsistent, or does not build lift pressure, remove the stretcher from service.
Inspect for Frame or Lift Component Damage
Check for bent lift arms, damaged weld areas, missing hardware, loose linkages, or signs the stretcher was overloaded or impacted.
Expected outcome: No obvious structural damage should be present.
If damage is found, remove the stretcher from service and escalate for repair or replacement evaluation.
Do Not Continue Cycling a Leaking or Drifting Stretcher
If hydraulic leakage, uncontrolled lowering, or failure to hold height is confirmed, stop functional testing.
Expected outcome: The stretcher is not used until repaired.
Why it matters: Continued operation can worsen the failure and create a patient handling hazard.
If the Problem Persists
If the stretcher still will not lift, feels weak, drifts down, or shows signs of hydraulic leakage after external checks, common user-correctable causes have been ruled out. The issue is likely internal to the hydraulic pump, cylinder, valve, seal, linkage, or lift assembly.
The stretcher should be removed from service, labeled Out of Service, and sent for repair or bench evaluation.
Knowing when to stop is proper troubleshooting. A stretcher with unreliable lift or height-hold function should not remain available for patient use.
Clinical Use Tip
Do not troubleshoot hydraulic lift problems with a patient on the stretcher unless immediate safety requires lowering or stabilizing the stretcher. Move the patient to another safe surface first. A drifting or weak hydraulic system can create a fall, transfer, or pinch hazard. Maintain therapy continuity by using a safe backup stretcher or patient surface before troubleshooting continues.
Work Order Documentation (CCR Method)
CCR = Complaint, Cause, Resolution
Complaint
What was reported by the clinical staff.
Example:
"Staff reported the Hausted Horizon 462 stretcher would not raise properly and slowly drifted down after pumping."
Cause
What was observed during troubleshooting.
Example:
"Verified weak hydraulic lift and height drift during unloaded functional testing; no external obstruction found."
Resolution
What action was taken.
Example:
"Removed stretcher from service, labeled Out of Service, and sent for hydraulic pump/lift assembly repair evaluation."
Helpful Details to Include (If Known)
- Alarm behavior, if any
- Whether accessories, linens, straps, or attachments were removed or repositioned during troubleshooting
- Power behavior, if any powered accessories or powered stretcher features were involved
- Environmental factors such as wet floors, crowded rooms, uneven surfaces, or signs of impact
- Indicator lights, if any powered accessory indicators were present
- Whether the stretcher lifted with no load
- Whether it drifted down after being raised
- Any visible hydraulic fluid or oily residue
- Pump pedal condition and travel
- Release pedal position and return
- Any abnormal noise, soft pedal feel, or binding
- Any visible frame, linkage, or lift arm damage
- Whether casters were locked during testing
- Final device status: returned to service or removed from service
Final Thought
Hydraulic stretcher issues should be treated as patient safety concerns, not convenience problems. Start with external checks such as obstructions, pedals, visible leaks, and release controls. Once leaking, drifting, or weak lift operation is confirmed, escalation is the correct repair path. Clear CCR documentation helps show what was tested, what failed, and why the stretcher was removed from service.
That is successful troubleshooting.
