"non-complete" pallet entry closure

[Kaji]

Hello I was asked to change a two-storey pallet lift to which to add a sliding door to the top floor for safety.
since I have little space on my hips, I haven't been given the precise data yet but should be 450 mm, as before I had thought of a telescopic door by elevator, unfortunately they already made the rollers and that of floor enters into the frame of the elevator then the classic door hanging over and guided below can not help to tighten their standard frame or "sacrify" a roller roller; I wondered if it was possible to make the doors of the sliding doors "only hanging" even though I have sincerely never seen it.

As an alternative, I had thought of a kind of storm that climbed from the bottom, but given the available space there would be a sheet that stops less than 2 meters from the ground, that is 1,4 meters above the roller coaster. As the expected height for the parapets is 110 cm, I wondered if to safety standards it was sufficient and also what other shortnesses should I observe for example to put micro position for the sheet, photocell and chain protection sheet that makes the movement?

Does the sliding door need to access the machine? a kind of physical shelter with possibility of opening for access?
Sincerely, not having your car in the head, I don't understand what you want to do.
If you have to protect the operator from the engine organs you have to apply the en 13857 for safety distances in addition to 14120 for shelters.
The 1100 mm high parapet serves for catwalks and to avoid falling but is not a shelter intended by 14120.
post a pattern. Hi.

thank you very much for all the information and I apologize for not being clear; from the door enter and exit only the pallets (or row of pallets up to 2050) to accidentally fall inside the operator should first climb on the floor roller, about 500 mm from the ground, and then lean inside.
However, I think I can solve the problems by using an automatic bellows door, the drag mechanism should be similar to the door door lift, only in this case only the first door leg needs to be driven even below.
