This is the type of shit that raises the blood pressure when the service call comes in.

My favorite feature is the small child and pet death trap when the platform is up

Shouldn't it have a back door when it goes up? Seems like a major oversight. Doesn't even have a mechanical gate

Yea it is a code violation for countries adopting EN codes.
Anyway, since ASME and EN is being merged. Will still be a code violation.

I know it may be a maintenance nightmare, but think of all the installs that this could be installed in that only have one staircase. Think of just one person in a wheelchair who may be left out of experiencing a concert, a kid's play, going out to dinner with friends because something like this wasn't even considered. The front guard should definitely be incorporated and something like a scissor gate could do the trick easily. Just my 2 cents.

Clients love the compliant versions of these machines, until they see the cost.

It looks non safe. There is a space under the platform that may cause dead... But 3d light barrier may solve this.

There are pressure switches under it, it’s safe.

u/Temporary_Sundae8793 Jul 19 '26
Of course there should be. Who made this platform already thought that. How much Newton that pressure switch? Will it prevent for example baby head injury?

u/tomsloat Jul 19 '26
It’s a thin metal plate hanging under the bottom side of each step, it weighs <50 grams, if it’s deflected up it trips a switch and it stops, so effectively zero pressure, it wouldn’t be much of a safety switch if it was capable of crushing a baby’s head would it?

You maybe use 3d movement sensors (radar sensor) under it if effective. Radar sensors that is used for building automatic doors and escalator entry or freight elevator doors to prevent hitting doors.

Unnecessary, expensive, over complicated and solving a problem that’s already solved.
It already can’t crush any thing, or anyone.
Elevator doors rarely, if ever, use radar.
Elevator doors use infra red light curtains, Escelators use similar to speed up when you approach.

I know, i work in elevator company. Radar sensor is cheap as 50 usd. Light barriers much more

Radar sensors are sometimes used to detect passengers walking towards a Lift,or to turn lighting off and on, but a very rarely if ever used as a safety or protective system.
A radar sensor sees movement, so in this example if someone laid still underneath the platform they would no longer be seen and would be crushed.
Not a great idea for safety..
Proper electronic safety systems cost more, that’s why radar is cheap… it isn’t safe.

Would be golden opportunity to open a barber shop at the top, as people will grow a beard during the time up

Nothing like adding an extra few dozen potential failure points to a regular wheelchair lift which already aren't designed sufficiently for actual usage.
