A trolley usually outlives its wheels, and a seized or split castor turns a working unit into an obstacle. Replacements are cheap and restore it entirely, provided the plate or stem pattern matches. Beyond that, straps and additional shelves change what a given frame can carry. Check the load rating still holds once shelves are added. See office trolleys, delivery trolleys and cleaning carts.
