    Anyone convert a Seated Stair lift to a platform stair lift

    I have a straight run of 14 stairs to basement. Used stair platform lifts are basically impossible to find, however, used acorn or other chair lifts with seat are plentiful. Do you think it would be that difficult to convert one. Possibly by removing seated chair and attaching a platform for manual chair to roll on and off I live in rural area and with a do it your self application don't really have to worry about codes as i would remove it before re-sale which will be after i am gone..

    I wanted to say no, but looking at mine it might be doable. My stairway is 36 inches wide, the Acorn seat carriage is 3-4 inches from the wall, but that is so the seat can turn. This leaves 25 inches clearance to the far wall, but mounting the track closer could give u[ to 28 inches for a platform if you tried to hang one from the chair carriage where the motor and batteries are. All you would be doing is removing the seat. It does seem to me you would need a track on the opposite side for stability, but that is a structures issue to work out. Space is the first one.
    I have had periodic paralysis all my life. I lost my ability to walk in 2011 beginning with a spinal block, which was used for a hip fracture caused by periodic paralysis.

      I think space wise it would work but support wise not sure either. Although the Harmar or Ameriglide units abot 8 to 11K only have rail on one side. Would love to find an old butler stair lift but have tried Disabled dealer one craigs and e bay no used stair platform lifts of any kind..

        I have one of these acorns, you might not see it, about to expire in NJ $350. https://www.ebay.com/itm/ACORN-BROOKS-Superglide-120-Stair-Lift-15-ft-max-length-w-Remote-LeftvHand/253712855380?hash=item3b1276f154:gREAAOSwMLha6Ksf

        Is transferring an issue? A second chair on the lower level is how I do it.

          Yes trying to limit transfers as much as possible I will be going down to basement daily probably end up going new if you ever run across a stair platform lift pm me i may not make final decision till this fall

            This one just came up, short for your need but it is the real deal at the right price:

              Yep would have to be about twice as long nice to know they are out there

                @pete4sake How is the project coming along? I'm interested in possibly doing the same thing. There seem to be a surplus of the seated lifts available 2nd hand, but I'm interested in an easily accessible platform also.

                  I think stair-lifts aren't suitable for conversion to a platform lift.
                  Stair lifts have the mass centroid only slightly outboard of the tack, perhaps even above it.
                  A platform cantilevers this weigh and imposes a function way beyond the stair-lift's design.
                  Even if you put a secondary track on the stairs to pick up some of that load, the torque from such might upset the carriage which is designed to take up virtually none.

                    I would agree with pfcs49 the torque with the weight being pushed too much past the chair base would damage the lift. I do have a second chair downstairs so I can do laundry. My lift failed this year with me stuck downstairs. Fortunately my son was home and was able to carry me up by piggy backing me.

                      I have no argument with Phil or Lavender, but when I look at either my Acorn or Bruno lifts it looks doable. As long as the weight is kept to a minimum, I would be tempted to try if I came up with something dirt cheap. The outrigger track might not be needed.

                          On second thought, if others can deal with the congestion, you could move the stair track out so it's centered under the platform, eliminating most stress.
                          Of course, that would require a raised lower platform and the requisite ramp onto it.

                            I ran into the same thing when I was trying to sort out access to my basement. Finally decided it made more sense to build a lift from scratch. If you are handy enough to attempt converting, you should be able to build what I built. All in, it cost me a little over a grand. That included the cost of a little wire feed welder. The basics of it are a wedge shaped carriage that runs on 2" angle iron "rails" which are lag bolted to each step ( Probably could have done every 4th step or so but I'm not an engineer). The carriage has a 12 volt deep cycle battery, an automotive winch, and 6 solenoids. The carriage has a total of 8 skate board wheels, two at each corner. One above and one below the rail. There is a wood framed platform with a short ramp at the bottom of the stairs ( I couldn't figure out a way to make the lift go all the way to flush with the basement floor without having the mechanism protrude through the door at the top of the stairs. I've since figured out a way to do it).

                            The carriage is normally parked at the bottom and is essentially part of the platform at the bottom of the stairs. When parked, it is connected via contacts to a 12v charger and to a doorbell switch at the top of the stairs. this functions as a "call" button. A limit switch was attached to a bumper bar along the back of the carriage to act as a safety in case anything got in the way of the lift on its way up. It would also shut off the lift when the carriage reached the top. A similar setup on the front would shut the lift off when it reached the parked position.

                            The cable runs out of the winch and, through a series of pulleys, up one side of the stairs, down through the top stair, across, back up, down the other side and attaches back to the carriage.

                            I'm new here and I haven't sorted out posting pictures yet, but if you are interested, let me know and I'll figure it out.

                              This sounds great. I'm trying to picture it, but would love if you could figure out posting pics. Or shoot them to me directly.
