A movable barrier operator includes a first side panel having a first opening and a second side panel, opposing the first side panel, where the second side panel has a second opening. The operator further includes a motor having a first side and an opposing second side including a first shaft extending in a first direction and a second shaft of the motor extending in a second opposite direction. The operator further includes a first bearing, the first bearing inserted into the first opening of the first side panel, wherein the first shaft of the motor is inserted through the first bearing and a second bearing, the second bearing inserted into the second opening of the second side panel, wherein the second shaft of the motor is inserted through the second bearing to thereby prevent transfer of vibration from the motor to the second side panel.

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.

In example implementations, an end cap for a panel of a vertically stacking panel door is provided. The end cap includes a body to be coupled to an end of a panel of a vertically stacking panel door, a first track wheel coupled to the body, a second track wheel coupled to the body, and a vertical stability roller coupled to the body, wherein the first track wheel, the second track wheel, and the vertical stability roller are arranged along a vertical line, wherein the first track wheel is located vertically above the second track wheel and the vertical stability roller is located between the first track wheel and the second track wheel.

The disclosure relates to a corner bracket (14, 16) for a vertical moving door (2), the corner bracket (14, 16) comprising: a base plate (32) configured to be attached to the door (2); and a guide path (34) for a lift cable (4, 6) arranged in the base plate (32). A switch (28) is arranged in the base plate (32) and configured to be actuated by the lift cable (4, 6) in the event of a breakage of the lift cable (4, 6). The disclosure further relates to a method, performed by a control device (200), for stopping a vertical moving door (2) of a vertical moving door system (100), the vertical moving door system (100).

The present disclosure is directed generally to automated trailer door systems for use at vehicle loading docks. At least a portion of the trailer door system can be externally driven for opening and closing trailer doors at the loading dock. The automated trailer door system can include a counterbalance shaft that moves the trailer door between a closed position and an open position; and a drive unit having a torsion member operably coupled to the counterbalance shaft; and a drive member rotatably engaged with the torsion member, the drive member having an engagement portion accessible external to the trailer door. Rotation of the drive member via the engagement portion can rotate the torsion member to move the trailer door between the closed and open positions. A door winder can be coupled to a centering body and have a motor to rotate the drive member via the engagement portion.
