Abstract
The present disclosure is directed generally to powered trailer systems and, more particularly, to powered trailer systems for opening and closing trailer doors at, e.g., a vehicle loading dock, and to vehicle and/or trailer power delivery and charging systems. A powered trailer door operating system can include a guide track having a lower guide track portion and an upper guide track portion; a drive support coupled to the upper guide track portion having a drive shaft positioned within a central cavity; and a carriage slidingly coupled to the drive support and operably coupled to the trailer door. The carriage can be operably engaged with the drive shaft through the slot such that rotation of the drive shaft causes the carriage to translate along the drive support, thereby moving the trailer door between the open and closed positions.
