Abstract
An elevator rail mounting system for positioning a pair of elevator guide rails, capable of centering an elevator cab therebetween, in a hoistway comprises a U-shaped bracket, mountable in the hoistway an adjustable distance from the entrance side thereof, for fixing the angular relationships of and distances between the guide rails, a landing sill and a hall door frame to insure a constant running clearance between the elevator cab and the landing sill and to maintain the proper alignment of the elevator cab and the hall door frame. The U-shaped bracket includes a horizontally and vertically adjustable cross member mounted from the entrance side of the hoistway substantially adjacent and parallel thereto. A pair of parallel rail brackets, spaced apart by a predetermined distance and extending into the hoistway perpendicularly from the cross member, support the guide rails in a vertical plane substantially parallel to the entrance side of the hoistway and maintain the distance between the guide rails at a predetermined fixed value.
