Has anyone here had cause to work on these systems?
I am tasked with repairing two of these where the return cogs have parted company with each other.
There is a steel plate let into the top of the frame which must contain some sort of spring or hydraulic mechanism.
I will call them on Monday but in the meantime thought I would mention the subject here.
I do like the way it swings a door on a huge hinge.
Cheers
Andy

Whilst I have no special knowledge of these, it looks to me as if the washers and fingers have worn and the door has dropped a bit disconnecting the teeth at the top. Be interesting to see what’s up there above the plate.

If it had dropped then I would have expected to see the paint line between hinge and door jamb to be cracked. But I can’t see that. I agree those teeth look worn

Another thought. How do they fit the door and manage to mesh those teeth at the same time? Could it be that the teeth/cog on the door is fixed to the grey disc beneath it and that that disc is threaded and therefore adjustable in height. Some form of set screw as a locking mechanism. Lower the disc/cog assembly to the bottom of its adjustment range, fit door, screw disc/cog assembly upwards to mesh into the upper set of teeth. Lock off

No, the LH side hasn’t moved it’s the wear between the fingers that has allowed the door to drop, must say it doesn’t look enough to cause the cog problem though.
I like your possible way to adjust the cogs, be good if it’s as simple as that.

I think there must be a way of adjusting the closing mechanism may be you drop the cog down and turn either the cog on the door or the inside the head to tighten or loosen it.

Looks like a spring assisted dismantling thing/finger remover to me.

But surely the door is held in the correct vertical position by the hinges which in turn are attached to that vertical lump of metal ?

Alas Ian no wear at all on the hinge.
Cannot at this point confirm wether the pin has dropped taking the gear down with it.

According to one of their engineers, whom the company kindly arranged to call me, to remove a door you have to unscrew both inside and outside lines of screws holding the hinge to the frame. This then allows you to move the bottom in/out to disengage the pivot point which is part of a bar let into the top of the door.
Things are getting a trifle confusing as the engineer doesn't think it is one of their products?
Theirs have zero gaps in the mechanisms to stop anyone putting their fingers/implements into it.
This job is on hold until I get time to look closer at it.

Looking at images online your photos Andy don’t look like the Kingsway anti-ligature design a search bought up.
I couldn’t get a close up but I’d have expected a brand name etched on those big plates, perhaps it’s a Chinese copy, in which case runaway

Your quite right Doug, no indication of maker at all but the older ones apparently didn't have them.
I really hope I can fix em as the alternative is two fire doors with swing hinges
Of course there is always the possibility that the closer mechanicals are worn out and unless I can find copies they're going to be bonkers expensive, IF they will supply them.
