Top 5 Problems with Wheelchair Lifts (and How To Solve Them)
Daily Operation Problems
Wheelchair lift issues in non-emergency medical transportation (NEMT) often arise during everyday use, causing delays and throwing off schedules. Knowing what can go wrong during regular operations is crucial for quickly addressing problems and keeping vehicles running smoothly. Below, we’ll explore common operational hiccups, focusing on hydraulic, mechanical, and securement challenges.
Safety Catch and Deployment Failures
One of the most common culprits behind deployment issues is the safety catch hook. These hooks are designed as backup safety mechanisms to prevent accidental lift deployment in the event of hydraulic failure. However, many operators mistakenly use them as part of their routine stowing procedures during transport.
When safety catches remain engaged, the lift won’t unfold as it’s designed to block deployment. This often leaves operators stuck at a pickup location, unable to deploy the lift - even though the system itself is functioning properly. To avoid this, always ensure the safety catch hooks are fully disengaged before attempting deployment.
If the handheld control pendant doesn’t respond after verifying the power switch, the issue might lie with the ground connection. Improper grounding - such as attaching the lift to the exhaust system instead of a proper vehicle ground point - can lead to system shutdowns and pose serious electrical and safety risks.
In cases where the controls fail entirely, you can use the manual backup pump to stow the lift and reset safety switches. However, frequent reliance on the manual pump signals a deeper issue, likely hydraulic or electrical, that requires professional servicing.
While safety catches and grounding are common trouble spots, inconsistent lift movement often points to other mechanical or sensor-related challenges.
Slow or Jerky Lift Movement
Uneven or jerky lift operation not only disrupts schedules but also raises safety concerns. If a lift moves sluggishly or with erratic motions, several factors could be at play, ranging from sensor issues to worn mechanical parts.
Barrier sensors are a frequent cause of slow or halted operation. These redundant safety sensors stop the lift if they detect an obstruction. Obstructions - like debris or misplaced items - can activate the sensors, slowing or halting the lift. Before forcing the lift to move, check for anything blocking the sensors. Removing the obstruction usually restores normal function in a matter of minutes.
Mechanical wear and tear also plays a role. For example, worn lift springs and hydraulic components can lead to jerky movements or leveling problems over time. Seasonal factors, like winter moisture, can cause corrosion in platform latching mechanisms, further affecting smooth operation.
If your lift consistently operates slowly, it may be due to an activated barrier sensor or a delayed hydraulic valve. Regular maintenance - like lubricating moving parts - can often resolve these issues. In some cases, resetting the system with the manual backup pump can fix minor glitches. However, persistent jerky movement or uneven leveling usually points to worn springs or hydraulic issues that require professional attention.
The key to distinguishing between a quick fix and a service call is understanding whether the lift is responding to a safety feature or experiencing a mechanical failure. Safety sensors and minor obstructions can often be addressed on the spot, but problems like worn components, hydraulic leaks, or electrical faults need expert intervention to prevent further complications.
Hydraulic and Mechanical Failures
Hydraulic and mechanical breakdowns can bring operations to a halt. Understanding how these systems fail is key to avoiding emergency repairs and keeping vehicles running smoothly.
Hydraulic Leaks and Pressure Loss
Hydraulic systems power the lifting mechanism, and when pressure drops, the lift can slow significantly or stop altogether. This issue often arises from leaks in hoses, connections, or seals within the hydraulic pump assembly.
To identify leaks, look for wet spots or puddles under the lift when the vehicle is parked. Focus on areas around the hydraulic pump, lift arms, and vertical rams, which handle the raising and lowering functions. Fresh hydraulic fluid is usually clear or amber, while older fluid may appear dark or brown. You might also notice an oily film on the lift platform or nearby components.
Low hydraulic fluid levels can also cause pressure problems. When the fluid runs low, the lift may only partially raise the platform or lower it unevenly. Inspect hoses for cracks, bulges, or wear at connection points. If worn seals are causing leaks, replace them to restore pressure and prevent further fluid loss.
After addressing leaks, refill the system with the recommended hydraulic fluid. Run the lift through several full cycles to ensure the fluid is evenly distributed and pressure is back to normal.
Worn or Damaged Parts
Mechanical components endure constant stress, and over time, wear and tear can impact lift performance. Spotting damaged parts early helps avoid unexpected breakdowns and ensures safe operation.
Frayed cables are a serious hazard. Hand pendant cables, which often get caught in doors, are particularly vulnerable. During inspections, check these cables for compression or fraying. If you see exposed wire strands, replace the cable immediately to avoid shorts or malfunctions.
Drift struts, such as the gas struts in BraunAbility wheelchair lifts, control the deployment and stowing of the platform. When these struts wear out, they may collapse too quickly, causing the platform to lower unevenly or prematurely. Signs of worn drift struts include the platform not staying level during deployment, lowering too fast after being raised, or needing manual support to stay raised. Replacing worn drift struts is the only permanent fix.
Springs in the lift arms are also crucial for smooth operation and leveling. Regularly inspect these springs for rust, corrosion, or visible cracks. Damaged springs should be replaced promptly to avoid operational issues.
Limit switches at the platform's edge can sometimes stick, disrupting lift cycles. During inspections, gently tap these switches to ensure they move freely. Stuck switches may cause the lift to stop unexpectedly or fail to complete its cycle. Cleaning around the switches and checking that wire harnesses are secure can often resolve minor problems.
Setting up a monthly or quarterly inspection schedule - based on how often the lift is used - can help catch wear and tear before it leads to failure. During these checks, look for frayed cables, rusted or damaged springs, and ensure all moving parts operate smoothly. Test all safety features by running the lift through a full cycle.
Keeping detailed maintenance records is another important step. Documenting inspections, repairs, and replacements can help identify patterns and predict when major components might need attention. Training staff to recognize and report unusual sounds, slow movements, or other mechanical issues early can prevent minor problems from turning into major failures.
Routine inspections and timely repairs keep hydraulic and mechanical systems reliable. For NEMT operators managing multiple vehicles, these practices not only extend the life of the lift but also reduce the risk of emergency failures that could disrupt service or leave passengers stranded.

Wheelchair Securement System Problems
After addressing mechanical and hydraulic concerns, it's equally important to focus on wheelchair securement systems to ensure the overall safety of lift operations.
Wheelchair securement systems are designed to protect passengers during transit. However, when these systems fail or are used incorrectly, the risk of injury increases dramatically. Improper securement is a major cause of wheelchair-related injuries during transportation.
Broken or Faulty Tie-Downs
Tie-down systems endure wear and tear from frequent use, exposure to the elements, and operational stress. Identifying signs of damage or failure is critical to avoid unsafe situations on the road.
- Frayed straps are one of the most common issues. You can often spot fraying visually, but it’s also helpful to run your hand lightly over the straps to feel for loose threads, cuts, or worn areas. Any strap showing signs of wear should be replaced immediately, as weakened material can fail under the stress of sudden stops or sharp turns.
- Failed retractors can cause straps to malfunction, either by not retracting smoothly or by failing to lock in place. If a retractor doesn’t maintain tension or lock securely, it’s time to replace the unit.
- Rust and corrosion are common in metal components, especially in areas with harsh winters or high humidity. Pay close attention to metal buckles, hooks, and floor-mounted anchor points during inspections. While surface rust can sometimes be treated, deep corrosion that compromises the metal’s integrity requires immediate replacement. In regions with winter weather, inspect platform latching mechanisms more frequently during colder months.
- Bent or deformed mechanisms - like outboard stop flaps - often result from excessive force during operation. These components should be repaired or replaced promptly to maintain the system’s integrity.
Damaged components, whether it’s frayed straps, rusted metal parts, or broken mechanisms, must be replaced without delay. Regular inspections and proactive maintenance are essential to ensure the system remains reliable and safe.
Incorrect Securement Methods
Even when equipment is in good condition, improper use can create serious safety risks. Correct positioning and proper operation of securement systems are just as critical as regular maintenance.
- Positioning errors are a frequent issue. Passengers must be fully within the lift’s boundaries before operation begins. If any part of the wheelchair or passenger extends beyond the platform edges, the lift’s safety interlocks will activate, preventing movement. This feature is designed to prevent accidents but underscores the importance of proper positioning.
- Misuse of safety features adds another layer of risk. For example, safety catch hooks are intended as emergency devices to stop sudden lift deployment in the event of a hydraulic failure. These hooks should never be used as a routine stowing mechanism. Instead, the lift should always be folded completely into the vehicle. Misusing these hooks could lead to unexpected deployment or equipment failure.
- Driver errors often cause damage to key safety features like outboard stop flaps. Excessive pressure on safety barriers or improper handling of flap mechanisms can compromise their effectiveness. Protective features such as rollboard barriers and inboard/outboard barriers are designed to prevent injuries and must be used correctly.
- Environmental factors can also impact securement. Deploying wheelchair lifts on uneven surfaces can lead to improper operation. Drivers should always park on level ground before using the lift to avoid deployment failures and potential safety hazards.
Addressing these issues requires well-rounded staff training. Training programs should emphasize:
- Demonstrating proper passenger positioning within lift boundaries.
- Using safety catch hooks only in emergencies.
- Verifying that vehicles are parked on level surfaces before deploying lifts.
Hands-on practice is key, especially for techniques like applying tie-down straps with the correct tension and ensuring secure attachment. Regular refresher courses and competency checks can help operators stay up-to-date with safety protocols, ultimately protecting both passengers and staff.
For non-emergency medical transportation (NEMT) operators, proper securement isn’t just about meeting regulations - it’s about ensuring passenger safety and building trust. Proactive maintenance and comprehensive training are the foundation of a safe, reliable service.

Tackling potential problems early not only cuts costs and minimizes downtime but also ensures passenger safety. A structured approach to inspections and record-keeping is what separates a reliable lift from one that frequently breaks down.
Creating a Maintenance Schedule
A solid maintenance schedule helps operators stay ahead of issues like hydraulic leaks, worn-out parts, and securement failures. Breaking tasks into daily, weekly, and monthly intervals ensures nothing gets overlooked.
Daily Inspections:
Before starting service, confirm the vehicle is running on the correct voltage, the seat belt is secured, the hand pendant wire is intact, and the control lights turn on when the power switch is activated.
Weekly Inspections:
Each week, examine key mechanical parts. Check the outboard stop flaps, inspect the platform for any damage, and listen for unusual noises or movements during operation.
Monthly Inspections:
Monthly tasks include cleaning the ground connection to avoid corrosion, inspecting lift springs, and, for BraunAbility lifts, checking the drift strut performance. Additionally, test the platform latching mechanisms, inspect electrical components like fuses and circuit breakers, and replace any faulty parts.
It’s also wise to follow the manufacturer’s recommendations for part replacements and adjust based on actual usage. Keeping an inventory of essential components - like fuses, springs, and hydraulic fluid - ensures quick fixes when needed.
Staff Training and Record Keeping
Even the most thorough maintenance schedule won’t work without a knowledgeable and consistent team. That’s why training and documentation are critical.
Teach staff that regular maintenance saves money in the long run. Assign specific personnel to handle inspections, and require them to sign off on completed tasks. Posting a simple inspection checklist near each lift can serve as a daily reminder. Incorporating lift maintenance into driver training and evaluations underscores its importance as part of their responsibilities.
Train operators to spot early warning signs like unusual noises, slower lift movements, or changes in control responsiveness. Electrical problems often start small - such as low voltage or a corroded ground connection - before escalating into major issues. Hands-on practice with inspection routines builds confidence and ensures consistent performance across the team.
Detailed record-keeping turns routine maintenance into a strategic advantage. Logs should include dates, times, staff names, completed tasks, and any identified issues or repairs. These records help track recurring problems, guide preventive actions, and assist in budget planning. They’re also crucial for regulatory compliance and can provide vital information in case of an incident.
Regular team meetings to discuss challenges, solutions, and lessons learned can strengthen a preventive maintenance culture. Celebrating milestones, like six months without lift-related failures, reinforces the importance of consistent care.
