I have a Stannah 400 which has developed a vibration on climbing, I think its muck on the rollers but how on earth do you get to them? Any advice would be appreciated

Is there muck on the sides of the rail?
If so then clean it off with a damp cloth, run the lift up and down loaded whilst its still damp, remove and muck laid down and repeat until clean after a few runs.
It’s more likely that your drive rack requires a little lubrication or the meshing may be out of alignment at the joins – I recommend you have someone from a local fim come in to check if the cleaning doesn’t sort it out.

How bad is the vibration? Is it worse when moving off from the bottom of the rail? As above if you as concerned enough to ask it may be time to have your lift serviced.

Thanks guys for the advice, a lot has happened since I posted. The Stannah has been serviced every year and the last service was only at the end of October when it was running fine. The track was clean but I thought the vibration was from muck on the rollers, I cleaned with a damp cloth and run it through a few times but it did not improve it, engineer came out Tuesday of this week, he cleaned it and changed the batteries as they were low got it working much smoother but as the day wore on it got worse, I called them out again on Friday as it was dreadful, they took it off the rail cleaned the rollers which they said were not in a brilliant state but still usable, they greased the drive rack and the deadweight for the cable by the time they left it was running smooth but again within hours the vibration started again. The vibration is quite severe on climbing the stairs, it tends to ease off nearer the top of the stairs, on the downward journey it has developed an almost lumpy ride with the motor straining then speeding up again. The engineers gave me two options as to possible cause, one- replace the rollers, two- replace the circuit board, both options are expensive, they quoted Â£40 per roller times 8 plus labour and the circuit board around Â£450. The problem I now have – is it worth repairing? The Stannah is 8 years old and is used a lot every day, if I am forced to carry out both repairs there is still no guarantee that it will work hence my dilemma. Any advice from you guys would be appreciated, I did think it may be worth getting another outfit in for a second opinion, what’s the best way forward?

Sounds like you’ve got a motor drive or gearbox fault as they have covered the basics.
I think the rollers are a red herring as the ride would be poor all the way up (unless the track is damaged), and £40 a roller is quite steep.
Has anyone actually checked the meshing and fixings are secure on the racking all the way up the track?
If I was in your position I would probably look at replacing the carriage for a newer reconditioned unit, the newer version has a few improvements which make the lift look a little tidier such as the trailing flex is no longer used and it’s still a good workhorse..
May be worth saying where you are located as one of the members on here may be able to offer you a deal.
I would say you would be looking at a £500 – £1200 dependent on the age of the new unit and the amount of work to covert the track. Or you could consider buying a new lift at under £1500 for something reliable.

Thanks Kevin, That’s a sensible solution, I am definitely in the market for a good recon Stannah or a new one, I am in Lincoln. Thanks for your help, Regards, Ian

I am a stannah engineer and it sounds like your motor gearbox is failing. It wont be the rollers and definetly wont be the pcb. You can get a rumbling on the down journey when the lift is not loaded caused by incorrect roller bogey torque. should be 4 nm .

Thanks to everyone, I am grateful for all the comments, this is a great forum. NsI Thanks for the 3, I will be contacting all of them for quotes, Dolphin installed this one so will start with them, ianb It makes sense that it’s the gearbox, the noise and vibration is dreadful now, the rumbling on the down journey is as bad when loaded, my wife tried it this morning (the stairlift is for her) and it really made her feel bad so I need to act quickly. Thanks again to you all, will let you know when this gets sorted which will obviously be after Christmas now. I wish you all a great Christmas and a Happy New Year. Regards, Ian

ian do you have an iPhone? if so can you video the lift in operation (include sound) and I will pm my email address if you could send the video.
MemberDecember 23, 2014 at 3:22 pm
ianb, I have been in contact with suppliers, have got Dolphin and Stannah visiting tomorrow for quotes. I think that is the way to go now, if as you say it looks like the gearbox then it would make sense to pull out the whole thing and start again, I was quoted yesterday for a new gearbox at £623 plus labour, at the end of that the 400 is 8 years old so its done well. Thanks and all the best, Ian
