Introduction
This design guide assists architects, builders, contractors, home owners and elevator professionals in planning for a home elevator installation that meets the requirements of ASME A17.1 Part V/CSA B44-13.
Please note this guide provides nominal dimensions and specifications and is useful for initial planning. Before starting construction please consult the specific application drawings provided by Cambridge Elevating that indicate exact dimensions for your project.
Please note that due to product enhancements and continually evolving codes, the information in this guide is subject to change without notice.
Planning for a Cambridge Elevating Home Elevator
The following planning procedure is strongly recommended:
1. Determine the customer’s intended use.
2. Determine the customer’s desired convenience level with respect to model type:
Elmira – swing landing door with manual (or automatic) accordion cab gate Heritage – swing landing door with automatic sliding cab door panels Cambrian – automatic sliding door panels on cab and each landing
3. Determine local, state and national code requirements of site.
4. Use pages 6 through 9 for hoistway construction, pit depth and overhead clearance requirements.
5. Use pages 10 and 11 to plan for a machine room and electrical requirements.
6. Use page 12 through 15 to determine car and hoistway size requirements.
7. Use page 15 and 16 to plan for the Cambrian model’s sliding landing frames.

Hoistway Construction – General Notes
A load-bearing wall is required to sustain rail reactions; please see Rail Wall Construction – Wood Stud
Wall (next page) for detail.
Hoistway must be in accordance with ASME A17.1/CSA B44-13, AND all local codes and regulations.
Pit floor construction must withstand a 5,500 lb. load.
Due to limited clearances, it
is necessary that hoistway walls be square and plumb. Maximum
permissible deviation from hoistway top to bottom is 1/8”.
Building structure must sustain a chain hoist for hoisting elevator materials to the top of the hoistway
during installation.
A structural engineer must ensure that building and hoistway can safely support all loads imposed by
the elevator equipment.
The drawings contained herein have been prepared using engineering principles and the design
loads that are applied by the rails to the wall. However the details and member sizes and the attachments to the structure should not be construed as a complete wall system. The contractor and/or the project engineer are responsible to evaluate the other loads that are applied to the wall from the floor or roof system and modify sizes or connections as required by their analysis.
