ASME A17.8-2021/CSA B44.8:21

Preface

This is the second edition of ASME A17.8/CSA B44.8, Standard for wind turbine tower elevators. It supersedes the previous edition published in 2016.

Originally, wind turbine tower elevators were covered in ASME A17.1-2013/CSA B44-13, Section 5.11, published in October 2013. This Standard supersedes those requirements. This is a fully harmonized binational Standard.

This Standard was prepared for use in Canada by the CSA Technical Committee on the Elevator Safety Code under the jurisdiction of the CSA Strategic Steering Committee on Mechanical Industrial Equipment Safety, and has been formally approved by the CSA Technical Committee.

This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

Scope

ASME A17.8/CSA B44.8 applies to elevators permanently installed in a wind turbine tower to provide vertical transportation of authorized personnel and their tools and equipment only.

Such elevators are typically subjected to extreme temperatures, humidity variations, and substantial horizontal motions where, by reason of their limited use and the types of construction of the structures served, full compliance with ASME A17.1/CSA B44 Part 2 is not practicable or necessary.
