Patent

CA 2531480

A method and apparatus for adjustably mounting tracks that suspend horizontal sliding doors at a freight elevator landing. The apparatus comprises a plurality of brackets adapted to be mounted in the shaft on the header above the landing opening. The brackets are each secured to the header with anchor bolts. Each anchor bolt is set in the header but initially allows vertical movement of the bracket. An adjusting screw, carried on each bracket, is arranged to easily and precisely move the bracket up or down relative to the anchor bolt as needed to position the tracks and, therefore, the door panels at a proper height. Once adjusted such that a specified gap is established between the lower edges of the door panels and the threshold, each anchor bolt can be tightened to fix its respective bracket in its adjusted position.
