SUPPORT TRUSS FOR HINGED OVERHEAD DOOR

摘要

An overhead door for closing a building opening has load distributing support trusses extending along spaced vertical members of the door or door frame. Each support truss is secured to a respective door vertical member to extend transverse to the door in a generally downward direction when the door is in an overhead, open position. The trusses are substantially V-shaped. Each truss has first and second rails extending from respective ends of the truss to an apex. One or more trusses may be side trusses secured to vertical members defining opposite sides of the door. Each side truss has a pivot mount configured for pivotal connection to one end of a hydraulic ram for opening and closing the door.
