There are nearly as many ways to install and align elevator guide rails as there are elevators. Installation techniques vary by company and even by geographical area. Experimentation on new and different techniques have been tried, and will continue to be tried, since the installation and alignment process can consume many hours and can make or break a job. The intent of this article is to focus on two of the more traditional methods. These methods have largely been accepted over the years as a tried-and-true way to install and align elevator rails. While other methods may prove faster, they normally require special equipment. The hoistway survey is the first part of any successful rail installation. During the survey installation, personnel must determine the vertical plumbness of the hoistway, whether it was built square and is in its proper location within the building. If there is more than one elevator, and they are adjacent to each other, the multiple hoistways must also be evaluated to ensure that their relationship to each other is correct. Particular attention must also be paid to ensure the elevator fronts line up and are parallel with each other. The end result of the survey is to ensure that the hoistway is built properly to allow the installer to place the elevator(s) into the hoistway in such a way as to satisfy all requirements of the job specifications.
