hello to all and thank you in advance to all those who will respond. the problem is as follows: you want to realize the plan (horizontal) of a common kitchen cabinet able to move vertically (maximum 500mm) by pressing a button. for this purpose I ask you how you would realize the movement: lazy racket? linear actuator screw-modrevite? hydraulic cylinder? belt chains or anything? I still ask what kind of guides to use and where it would be better to place them.

a little generic description... in these cases, a design, even very simplified, helps more than a thousand words. . .
first questions that come to mind:
What will he have to endure?
will everything be hidden or will some parts be visible?
is the mechanism under the plane or side (so with the bounce plane)?
simple or more refined solutions (and therefore, for example, more precise and quiet)?
frequency of operation? Do you have to move once a day, a month, or ten times an hour?

The system you will use depends on a number of factors, but for me the screw-modrevite (4 at the corners of the floor or a central on the guided plane) allows you to integrate the guide system to that of movement, to have robustness and precision of positioning as well as a discreet silence.

Alternatively, there are also ready-made motorized parallelogram systems. :smile:

pantograph, spring plywood (also gas spring), mechanical cylinder drive (electric motor and ball recirculation shaft).
the compensation should keep in balance about half the maximum nominal load (if it is for a kitchen it should suffice 50 kg), if the max load drops slowly and remains.

Thank you. I will shortly post some drawings. we say that you must see the least possible for which to put mechanisms under the plan would not be ideal. I was thinking of putting the actuators or behind the front, a central or two towards the edges plus 4 guides, two on each side plane. In this case, however, the plan would be to "balance". or perhaps it would be better to use 4 actuators in correspondence of the side faces? for both modes you could hide everything with a double bottom. the idea of using two or more actuators equipped with each electric motor and operated simultaneously does not create problems? that is, even if the same is not the risk that there are interferences due to the fact that maybe they do not move exactly at the same speed? the masses above the floor are about 50 kg.

there are theseor produces something also the skf.
are complete solutions, but not very economical.

Bye!
