An exemplary mounting arrangement for an elevator machine comprises a first portion () and a second portion (). The first portion and the second portion are moveable relative to each other between a shipping position and a deployed position in which the first portion and the second portion are generally perpendicular to each other.

Elevator system and installation method

A structural system for elevator assemblies includes a horizontal compression member positioned near the top of the elevator hoistway for reacting to inwardly directed tension loads and moment forces applied to the hoistway wall and connection components resulting from the elevator vertical load. The horizontal compression member includes a rigid member positioned in a compression state between mounting structures for elevator ropes and elevator machine components such that the compression member reacts and counters inwardly directed horizontal forces and resultant moment forces caused by a centralized, downward vertical load.

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.
