I have the recent GOLD MEDAL/SWJX 7 version of the operating milk car.  For a year plus it operated flawlessly, until the other day, when it displayed the same behavior as yours.  2 small philips head screws on each end, and the box can be separated from the floor.  The cans just got stuck.  A couple blasts of compressed air cleared away whatever microscopic dirt/dust was there, and I was back in business.
