前言这是ASME A17的第二版。8/CSA B44。8，风力涡轮机塔式电梯标准。它取代了2016年出版的前一版。最初，风力涡轮机塔式电梯包含在ASME A17中。1-2013/CSA B44-13，第5.11节，2013年10月出版。本标准取代这些要求。这是一个完全协调的两国标准。本标准由CSA机械工业设备安全战略指导委员会管辖下的CSA电梯安全规范技术委员会编制，供加拿大使用，并已由CSA技术委员会正式批准。本标准的制定符合加拿大标准委员会对加拿大国家标准的要求。 CSA集团已将其作为加拿大国家标准发布。范围ASME A17。8/CSA B44。8适用于永久安装在风力涡轮机塔架上的电梯，仅用于垂直运输授权人员及其工具和设备。此类电梯通常会受到极端温度、湿度变化和大量水平运动的影响，由于其使用有限和所服务结构的构造类型，因此完全符合ASME A17的要求。1/CSA B44第2部分不可行或不必要。1.1.1生效日期本版本和后续标准补遗的要求自本文件版权页注明的日期起生效。 有管辖权的当局将确定其地方法规的生效日期。

PrefaceThis 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.ScopeASME 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.1.1.1 Effective date The requirements of this edition and subsequent addenda to the Standard are effective as of the date noted on the copyright page of this document. The authority having jurisdiction will establish the effective date for its local regulations.
