Safety issue / Grizzly

[Cagou]

I need more information about the access on a grizzly. What is the standard opening that allow workers to walk on it. Operators need to maintain some equipment that can only be reached using the grizzly. At this time the openings are too small, and the material can't get through the grizzly, I need to make them bigger, while respecting safe access.
Thanks,
