That changes where damage travels, and it makes **tie down anchorage** a structural item. ## What does paratransit van repair involve? Paratransit van repair covers the converted lowered floor pan and its rails, the ramp or platform lift mounting structure, the rocker and sill after curb contact, and the tie down anchorage in the floor. Rancho Santa Margarita agencies and providers have this work done in shop at our Yorba Linda facility. - The conversion removed original floor structure and replaced it - Rocker crush from a curb travels straight into the lowered pan - Tie down tracks are anchorage, not accessories - Ramp and lift structure is ours; lift certification is not ### Key facts | Item | Value | | --- | --- | | Platforms serviced | Ford Transit, RAM ProMaster, Chrysler Pacifica, Ford E-350 cutaway (BraunAbility, Vantage Mobility and Rollx conversions) | | Structural rate | $210 per hour (Electrical and lift circuit work at $260 per hour) | | Typical length | 17 to 22 feet (GVWR 6,050 to 11,500 lb depending on platform) | | Anchorage standard | Occupant restraint pattern restored (Q'Straint QRT and Sure-Lok track reinstalled to original layout) | | Written estimate | $150 (Credited in full against an authorized repair) | A paratransit van is a factory vehicle that had a large hole cut in the middle of it on purpose. To get a ramp entry and interior standing height, the converter removes the original floor pan and part of the structural cross members, then fabricates a lower pan with new rails and reinforced rockers. The finished van drives like a van and repairs like nothing else on the lot. That matters the first time one comes in with a rocker scrape from a curb at a passenger stop. On an unconverted van that damage would stop at the rocker skin. Here the rocker is part of a fabricated load path holding a lowered pan, and the deformation keeps going until something inboard absorbs it. ## What the conversion actually removed To get a ramp entry and usable interior height, a converter cuts out the original floor pan and part of the cross members underneath, then fabricates a lower pan with new rails and welds reinforcement into the rockers and pillar bases around the opening. BraunAbility, Vantage Mobility and Rollx all do a version of this, and each publishes its own reinforcement layout. The consequence is that the factory body repair manual only describes half of the vehicle in front of you. Before we write a scope we identify the converter and the conversion generation, because the rail layout under a 2016 Transit conversion and a 2022 one are not the same. Guessing at that is how a repair ends up strong in the wrong places. - Original pan and cross members removed at conversion - Fabricated pan, new rails and welded rocker reinforcement added - Reinforcement layout is converter specific, not chassis specific - Factory body repair data covers the untouched half of the van ## Why a curb scrape is not a rocker job here Paratransit vans load against curbs all day, so rocker contact is constant and mostly cosmetic. The moment it stops being cosmetic is when the contact was hard enough to dent, because on a converted van the rocker is welded to the reinforcement that holds the lowered pan. Push it in and the load has somewhere to go, inboard, into a rail that was fabricated rather than stamped. We measure the pan rails and the door opening before deciding anything, using the opposite side as the reference. Straightening a rocker skin on a van whose rail has moved a quarter inch produces a vehicle that looks correct and never quite closes its door the same way again. ## Tie down tracks carry people, not cargo Q'Straint and Sure-Lok securement systems transfer occupant load into floor track, and that track is usually bolted through a fabricated pan with backing plates behind it. When a strap tensions and the track lifts even slightly, the fastener or the plate under it has already failed. We remove track rather than inspect it in place, because the failure is on the underside. Replacement goes back in full lengths to the original station layout with new backing plates and correct hardware. We do not splice a track across a securement position and we do not move a station to make a repair easier. The layout was designed around wheelchair footprints and turning space, and changing it changes whether the van can carry the passenger it was bought for. > **warning:** If a securement strap has ever pulled a track up off the floor even a little, the van should be out of service until the anchorage is opened up. That is not a maintenance item that waits for a scheduled visit. ## Ramp and lift structure compared with lift service There is a clean line between what we do and what a mobility service company does. We repair the structure: the hinge plate and the metal around it, the door opening, the reinforcement, the pan the assembly bolts through, and the refinish afterwards. We also reinstall to the manufacturer's fastener specification and cycle the assembly under load before release. Hydraulic and control faults, actuator replacement, interlock programming and lift certification all belong to the mobility equipment specialist. On agency vehicles we work alongside whichever provider holds that contract, and we sequence our structural work so their inspection happens after the metal is right rather than before. ## Power for a ramp is not a cigarette lighter circuit Ramp and lift power is a heavy draw on a dedicated feed with its own protection, an interlock tied to the transmission and door state, and a control head the driver uses dozens of times a shift. After a side impact the damage we look for is chafe and pull at the harness where it crosses the reinforcement, not just at the connector. Diagnostics on that runs at $285 per hour with a one hour minimum, credited against an authorized repair, and it buys a documented reading at each stage of the feed rather than a replaced control head. Once the fault is found, repair labor moves to the mechanical rate of $260 per hour. ## Getting the conversion valued properly The single most expensive mistake on these vehicles is letting a carrier evaluate one as a base van. A conversion can represent a third of the delivered cost of the unit, and none of it appears in a used vehicle guide. When the file arrives without a conversion invoice, the total loss math runs against the operator every time. We photograph and itemize the conversion at teardown: converter plate, ramp assembly, securement stations, seating positions, floor layout. Providers keeping their own records should hold the original upfit invoice with the title documents rather than in a maintenance folder. ## Intake, downtime and getting the van here Providers running scheduled trips cannot lose a van without a plan, so we book these as fixed date jobs and stage the parts before intake wherever the damage allows it. A rocker and pan repair with refinish is typically six to twelve shop days. Anchorage work alone is often three. We do not offer mobile repair, and no part of this business is a roadside service. Drivable vans come to the Yorba Linda facility under their own power, and anything that cannot be driven arrives on a tow. From the Rancho Santa Margarita area the 241 to the 91 is the easy run. ## Questions and answers ### Is a dented rocker on a lowered floor van a structural repair? Usually yes. The conversion welded reinforcement into that rocker to carry the lowered pan, so a dent means the load path has been pushed inboard toward a fabricated rail. We measure the rails and the door opening against the opposite side before deciding, because straightening the skin alone leaves a door that never closes the same way twice. ### A securement strap pulled the floor track up slightly. How serious is that? Serious enough to park the van. Track anchorage carries occupant restraint load through backing plates on the underside of a fabricated pan, so a track that lifts means a fastener or plate has already given way. We remove the track to inspect from below and replace in full lengths to the original station layout with new hardware. ### Why do you need to know which company converted the van? Because the reinforcement layout is theirs, not the chassis manufacturer's. BraunAbility, Vantage Mobility and Rollx each weld in a different rail and rocker plan, and layouts change between model years. Factory body repair data only describes the half of the vehicle the converter left alone, so we identify the converter before writing a scope. ### Why is the rust on my lowered floor along the weld lines? Because the pan is fabricated and joined with long seam welds and sealer rather than pressed as one piece. It is also the lowest metal on the vehicle, so water running off a ramp and spray off the road both settle into the seam. It corrodes at the joint first and in the panel field much later. ### How do I stop a carrier from valuing my van as a base model? Put the conversion invoice in the file at first notice. A mobility conversion can be a third of the delivered cost and appears in no used vehicle guide. We itemize and photograph the converter plate, ramp assembly, securement stations and floor layout at teardown so the valuation has documentation to argue with. ### Can you fix a lift that stops halfway through its cycle? Not the hydraulics or the controls. That is mobility equipment service work and it belongs to the company holding that contract. We handle the structure it bolts to, the hinge plate and surrounding metal, the door opening and the wiring feed, then reinstall to specification and cycle the assembly under load before the van leaves. --- Source: [OCRV Center](https://ocrv.me/vehicles/buses-and-fleet/paratransit-van-repair/).
