A universal bracket for a rail system includes a positionable and alignable main support and at least one mounting point for at least one rail of the rail system. The main support has two guides that are inseparably connected to the main support in order to guide one plumb bob in each case, the mounting point and the guides being arranged in fixed positions relative to one another.

The present invention includes machine room unit hoisters 9a, 9b, 9c by which a machine room unit 6 is suspended from a support member provided in a hoistway so as to be movable in an ascending/descending direction. The machine room unit hoisters 9a, 9b, 9c suspend the machine room unit 6 at suspension points 21a, 21b, 21c. The machine room unit hoisters 9a, 9b, 9c are provided, supported by the support member. When viewed from a virtual horizontal plane over the machine room unit 6, distances from a center G of gravity of the machine room unit 6 to each of the suspension points are substantially equal and the center G of gravity is positioned within a region enclosed by virtual straight lines connecting each of the suspension points 21a, 21b, 21c. When viewed from a virtual horizontal plane over a working platform 5, the respective suspension points 21a, 21b, 21c of the machine room unit 6 are positioned outside a contour of the working platform 5.

An elevator guide having a base attached to an elevator component, a guide riding along a portion of a rail and a spring biasing the guide in contact with the rail. The guide includes one or more of the following: (i) a guide support member operably associated with the guide for movably supporting the guide so that the guide can move toward and away from a corresponding surface of the rail member wherein the guide support member has a plurality of spring engagement sections configured to vary a system effective spring rate; (ii) a roller including a non-metallic rim molded about a bearing; (iii) two independently adjustable stops and, (iv) an opening adjustment member mounted about a notch in the base to vary the distance between the base and the rail. The opening adjustment member has a width and/or depth greater than a width and/or depth of the notch.

A system for transferring elevator cars from a first elevator shaft to a second elevator shaft including: a propulsion system configured to move an elevator car through the first elevator shaft and the second elevator shaft; a transfer carriage configured to move the elevator car from the first elevator shaft to the second elevator shaft through a transfer station, the transfer carriage including: an elevator car containment slot to receive the elevator car; and a car retention mechanism configured to secure the elevator car and the propulsion system within the transfer carriage while the transfer carriage moves from the first elevator shaft to the second elevator shaft, wherein the propulsion system is configured to move the elevator car from an elevator system within the first elevator shaft onto the transfer carriage and off the transfer carriage to an elevator system within the second elevator shaft.

A modular elevator assembly and a guide rail. The modular elevator assembly includes: a bottom module; a top module; at least one intermediate module being configured to be removably stacked between the bottom module and the top module; and wherein each of the bottom module, the top module and the intermediate module includes a plurality of guide rails, and the cross section of the guide rail includes: a first section extending along a length direction of the guide rail; a second section extending in parallel to the first section and being attached to the first section; and a transition portion connecting between the first section and the second section and being configured to provide a cross-sectional profile that transits between the first section and the second section; and wherein the guide rail further includes a connection structure, the connection structure is configured to connect the guide rails.

A guide rail support of an elevator includes a guide rail bracket having a first side, a second side, a first mounting portion, and a second mounting portion. The first mounting portion is attachable to an elevator shaft and the guide rail bracket has inclined apertures in the second mounting portion. An adjustment bracket is configured to contact the second side at the second mounting portion, the adjustment bracket having inclined apertures configured to align with the inclined apertures of the guide rail bracket to define stem apertures.
