Мне особенно непонятно ***compactor floor*** и ****skip exchange****

GR - вроде бы guest/receipt (area)

Вообще, речь идет о строительстве крупных магазинов/гипермаркетов

Вот абзац полностью:

GR compactor / area. Is the GR compactor floor reinforced to prevent skip exchange damage? Is there a canopy for inclement weather? Is there an operation safety device to prevent personal injury whilst in operation?
