Concept 1 By John Huizingh on 22 Dec 08:05

Nice one. Same concept I'm going to... but I don't have time to do it now.

Ok, I now had some time, I am not sure if I will have the time to completely finish it. But I would like to see how you solve the stability issue of the frame. I think the 2 beams are currently in the way when sitting. For the rest I do not think the 500kg is an issue, because normally one piece is lifting a car, so maybe the lifters can be downgraded.

You mean you will add 2 beams?

Regarding 500kg - you are right, one car-jack can do the 500kg job :) ...2 times ;)

No I mean the 2 long profiles which now connect the 2 frames at the side. I think they can not be there. I will add 1 instead of 2 and see how it looks like.

Hmmm... try and then show us :)

This is what I meant, see rendering. Now one profile in the middle and also a lot higher, so more space for your knees. I will add the sitting person also.

Its an intresting concept. Might be a little unstable, and the bar in the middle might be a problem when using the table.

But i think those things can be fixed.

Tobias, thanks for the comments, I have updated the design.

Much better...

Отчасти иде неплохая.
Изначально я продумывал идею такого плана, но потом решил отказатся, так как, чтоб поднять конструкцию с нижнего положения необходимо приложить усилие около 7 тон на сторону.
Если вы хотите чтоб конструкция работала то необходимо задать начальный угол от горизонта не мение 45 градусов ( но нагрузка будет все равно большая ).

Part of the ideal good.
Initially, I thought over the idea of ​​such a plan, but then decided to unsubscribe, so as to raise the structure to its lower position to make an effort about 7 tons per side.
If you want your design work is necessary to specify the initial angle of the horizon does not menie 45 degrees (but the load will still be large)

That was much better. Nice with the Sovella logo on the side there also.

Beam in the middle is in the way for the knees. So I have to get rid of it. I will move it backwards which is a pity because when it could be in the middle it did not matter how you would place the table, both ends were the same.

Seems a bit complicated for an adjustable workbench.
I've seen ones with hydraulic pistons in the legs instead.

Blair, Yes I know them, but it only may cost 350 to produce and when I see the prices in your link , i do not think this is produced for that price
