or one or the other however for door 100 the horizontal and vertical trussing are interconnected to distribute load in both the horizontal and the vertical directions to accomplish this the horizontal and vertical trussing is constructed as shown in greater detail in fig1 a individual vertical truss member 152 and individual horizontal truss member 154 are shown at an intersection 156 thereof horizontal truss member 154 has an opening 158 through which vertical truss member 152 extends horizontal truss member 154 has opening 158 configured in size in one embodiment to fit a width 160 of vertical truss member 152 sides 162 and 164 of horizontal truss member 154 are on either side of the vertical truss member 152 because of this when assembled the truss members 152 and 154 provide a distributed load from stress from either side of the door in one embodiment the vertical truss members 152 and vertical truss members 154 are joined at the intersection 1566 for example by bolting welding epoxying or the like the interconnection of the vertical and horizontal truss members spreads a load on the door 100 over the entire frame loads such as from lifting of the door 100 and wind loading are dispersed both horizontally and vertically as opposed to traditional loads being dispersed only vertically door hydraulics 108 are connected between the frame 106 and the door body 110 so as to open the door 100 by moving the door body 110 in response to the door hydraulics 108 hydraulics 108 are hinged so as.
