Lift shaft dangle - Schindler 3300 & 5500 

this is a very unsafe event. and professional people will not act like this stupid.

Professionals are people who are regulated and registered with certain lift saftey boards and theyre enginners

Actually I've just realised the simplest thing to do is have a small length of chain you can wrap round the beam and hook into.

The edges were not sharp, but I should have had a cloth to put over the beam to soften it. Also, how Jordan did that dangle was even worse. He side loaded the carabineer by wrapping the sling around the beam and clipping it back onto itself instead of his harness.

@@benolifts Just because the corners aren't sharp doesn't mean they won't cause damage. Hard edges will over stress the strap and cause it to de laminate gradually. If you get a length of heavy chain say the length of your forearm you'll be fine. That won't be damaged by anything you wrap it around.

And ideally you should have 2 independent hang points just to be safe. So maybe get 2 lengths of chain and 2 carabineers you can hook into 2 different locations on your harness.

With the lifts with the top hook, there is usually only one of them. They usually have a tag of when last inspected. It is often years ago. I am putting all my trust in it.

As far as I know, in the UK the pre door relays need 2 separate shaft bars and relays , although Germany uses 3 (correct me if I am wrong). Most lifts in the present day use magnets instead of bars. So either 2 separate magnet switches have to be false triggered at the same time, or 2 relays have to be stuck open. In addition to this, the logic would have to activate pre-door relay circuit and keep the circuit running and at the same time the VF drive would have to not hold the lift and allow it to slip, and the logic would have to keep the pre door circuit active despite being programmed to stop it when it detects an error. Lets look at all 4 things that have to have failed (labeled as 1, 2, 3 & 4) and where there is 2 options (1A and 1B) then one of the two would have to fail. 1A - Both pre door shaft magnet readers are false triggered. 1B - Both pre door relays are stuck closed 2A - The VF drive fails but VF-OK failed to cut out 2B - The VF drive failed to hold the lift still 3 - The logic keeps the pre door circuit active despite seeing that the lift is moving outside its tolerance 4 - The logic's relay monitoring failed to notice that the pre door relays are true when they shouldn't be It is very unlikely that pre-start would cause a major failure. There is no more risk than with pre-doors and relevelling that use the exact same procedure. But it is likely that the pre-start could fail and the lift starts moving away and looses safety once it has moved 30cm. I have actually seen this happen once and it was rather startling.

@@benolifts so the 5500 has a prestart like the eurolift

@@user-kf6jv5jk2j Yes

He has done quite a few.

@@TheDragonFire123 hi

If you mean in case the lift overruns the top floor, there's a brake release to freefall the lift back down again. You'll need to load it to about full capacity or thereabouts, then pull the brake.

@@TheDragonFire123 OK so can you release the brake from the top floor doors.?

@@andrewthompsonuk1 From wherever the logic cabinet is.

@@TheDragonFire123 so is there a cable or something mechanical to pull at the cabinet?

@@andrewthompsonuk1 That, or an electronic gadget that does that for you.

The hook has to lift the motor, which is much more heavy than a person. I look at when it was last inspected and if more than 5 years ago I don't do it.

No that's electrical drawings.

hey guys austin is lift dangling

Greetings guys this is tea time.

3300's are everywhere, not sure where you at looking...

@@Krambo19 I said they were uncommon here in Australia, not everywhere

@@LachieVidsTransportVlogs thats not true, 3300's are probably one of the most common lifts in Australia

@@Krambo19 Well, not In QLD. I’m saying they are uncommon compared to other lift models, such as the 5500 and monospace, not that they are as rare as an EPL or something.

ok

ok who asked

irresponsible actions!

Beno is a engineer 👷‍♀️ he has special permission

@@KLTRF I am not an engineer. I did this without permission.
