For some while I've been pondering with an ADT build myself, but it likely won't happen for real for a few years more.

Anyways, I was playing with the idea of using gas springs for the bed lift (very cheap) and then a powerful gear motor to pull it back down again with a wire rope. I was thinking something like 2x15kg gas springs 150mm stroke:

and this gear motor:

And then some wire rope around 1mm thickness:

There is very little extra room to go on for the cylinder with the very long stroke they have to have to get a proper angle on the bed when tipping. I don't think an inline electric motor (like in the electric actuators) will enable you to get a cylinder that mounts in the normal positions or will provide the normal tipping angle for the bed.


Best regards,

That's a good idea for lifting the box. I'm gonna try the actuators from actuonix first as I have a few sitting around.

Also I think I'm gonna change my mind with steering and go to a large scale servo. The gear motor would be good but can't get it to auto center and be harder to control I think.
