Abstract: A swing type garage door has one or more of several features, including a door body rotationally connected to a door frame, the door body having one or more of: a trussing system having vertical and horizontal truss members, the horizontal members having openings through which the vertical members extend to distribute a load on the door body to the door frame in both a vertical and a horizontal direction; first and second sections hingedly connected with a hinge to allow ease in transport; a main door body section and a door load truss section hingedly connected at a bottom of the main door body to provide load trussing when the door is open; and at least one brace rotatably connected to the door body on an interior thereof and rotatable between a first bracing position and a second storage position to brace in high wind loading conditions.

Abstract: A system and methods for controlling operation of hydraulic cylinders includes monitoring position of the cylinders relative to one another, and correction of misalignment of the cylinders should they become misaligned. Further, monitoring can be of a swing-type door operated using the cylinders, which can operate the door at different speeds. Further, as the door creeps open from a closed position or closed from an open position, correction is also made.

Abstract: A hydraulic door opening mechanism for overhead bi-fold doors is herein disclosed. The door opening mechanism mounts a hydraulic pump, pressure reservoir, valve manifold, and a hydraulic motor or cylinder on a first door panel. The door opening mechanism is pre-assembled with the doorframe prior to mounting the door in the door opening.
