What the door is for
A closed bulk container has to be tipped or lifted to empty it. This one does not. Release the two steel rods and the panel drops clear, so the contents can be reached, raked or scooped from standing height.
The panel is 370 mm deep measured down from the rim, which the drawing dimensions directly. That is the working opening you get in the top of the wall.
This matters most where a box is emptied part-way and repeatedly, which is the normal pattern in food preparation, on a picking line, or anywhere a forklift tipper is not available.
