Abstract

An improved method for mounting elevator rails within a hoistway includes the initial step of securing support brackets to a pair of rails. The brackets, rails, a machine for driving a cab and a dead end hitch are then mounted within the hoistway. A cab may then be moved vertically within the hoistway and additional support brackets are placed at vertically spaced locations. The connection of the brackets and rails provides support to dissipate the loads which are transferred into the rail in such systems wherein the machine or the dead end hitch is fixed to a rail. Once the rails have been adequately supported by additional brackets, the brackets which are secured to the rails are removed from the rail. The brackets provide support, but are no longer fixed to the rails.
