ASME A17.8-2016/CSA B44.8-16

1.1 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. 1.1.1 Effective date The requirements of this edition and subsequent addenda to the Code are effective as of the date noted on the copyright page of this document. The AHJ will establish the effective date for its local regulations. 1.2 Definitions The following definitions shall apply in this Code: Authorized personnel — persons who have been instructed in the operation of the equipment and designated by the owner to use the equipment. Brake, driving machine, elevator, dumbwaiter, or material lift — an electromechanically or electrohydraulically released spring, or gravity applied device, that is part of the electric driving machine of the elevator, dumbwaiter, or material lift used to apply a controlled force at a braking surface to hold or retard the elevator, dumbwaiter, or material lift. Electromechanically released — a means of brake release in which an electric current applied to an actuator (such as a solenoid) causes an electromagnetic force that overcomes a resisting force (such as a spring) as long as the electric current flows. Buffer — a device designed to stop a descending car or counterweight beyond its normal limit of travel by storing or by absorbing and dissipating the kinetic energy of the car or counterweight. Spring buffer — a buffer utilizing one or more springs to cushion the impact force of the descending car or counterweight. Bumper — a device other than an oil or spring buffer designed to stop a descending car or counterweight beyond its normal limit of travel by absorbing the impact. Cable, traveling — see Traveling cable. Capacity — see Rated load. Car, elevator — the load-carrying unit including its platform, car frame, enclosure, and car door or gate.
