ok, I hope to be clear in my question for my first one on this SE site.
I'm trying to design a trolley divided in several compartments.
Each compartment will correspond to a set of wood pieces. These pieces are cleats (not sure of the english translation for that: I mean long pieces with small section) of wood with a section of about 100x100 millimeters and which are up to 3 meters long. And the trolley is designed so that the wood pieces are placed vertically.
These pieces of wood are produced (cut) by a machine which delivers each of them about every 20 seconds.
From the machine output (a conveyor, so the pieces of wood lay at the horizontal) to the trolley, the pieces of wood are handled by a human person.
The question is:
What are the ergonomic rules (or studies for this situation...), about taking a long piece of wood which lays horizontally, by a human person, at around 1 meter up on the convoyer, to some location where this piece of wood will be placed vertically. So that, the pieces of wood will need to be rotated from horizontal to vertical by the person?
Here is the context. A convoyer which carries pieces of wood. And in front of it the trolley with several locations.
The question is about: is, for a human, acceptable to take the pieces of wood from the conveyor and bear/rotate them to the trolley?
