ANSI B77.2 pdf free download.Funiculars一 Safety Requirements.
It is recognized that certain dangers and risks are inherent in machines of this type and their operation. It is also recognized that inherent and other risks or dangers exist for those who are in the process of embarking，riding， or disembarking from funiculars. This system is intended to result in funiculars that are designed, constructed, operated, and maintainedin a manner that helps reduce danger, exposure torisk to passengers and maintenance and operational personnel, and to encourage improvements in productivity，efficiency, development, and progress consistent with the objectives. Such a system with these stated objectives constitutes a safety standard.
1.2.1 Other classifications Funicular configurations that do not fall within the definition specified in 1. 4 – funicular, but fall within the general category of funiculars should be evaluated by the authority having jurisdiction based upon the design engineer’s specifications and the applicable provisions of this standard.
1.2.2 New materials and methods for funiculars Adoption of technological improvements in materials and advances in techniques is essential to enable the industry to keep pace with progress. If a designer or manufacturer proposes to use materials or methods not covered by this standard, those materials, methods, or both, shall be clearly identified. Complete design and test information shall be provided to the purchaser or the owner and the authority having jurisdiction (see 1.4 – authority having jurisdiction).
1.2.4.1 Existing installations Existing installations, and those with design review completed by the authority having jurisdiction prior to the effective date of this standard, need not comply with the new or revised requirements of this edition, except where specifically required by the authority having jurisdiction. Operation and maintenance shall be in compliance with those requirements specifically listed (not included by reference) in the operation and maintenance subsection 2.3. and normative Annexes A and F in the most current edition of this standard.
1.2.4.2 Relocated installations An existing funicular, when removed and reinstalled, shall be classified as a new installation (see 1.2.4.3).
1.2.4.3 New installations New installations, and those with a design review completed by the authority having jurisdiction after the effective date of this standard, shall comply with the new or revised requirements of this edition.
1.3 Reference to other codes and sta ndards The design, installation, operation, and maintenance of funiculars and their components that are not covered by this standard should conform to applicable standards or codes. To the extent that they are available，applicable codes or standards shall be selected to cover all features, including, but not limited to, ADA，allowable unit stresses, and properties of materials. Each code or standard should be of the most recent issue, and the designer shall state which code or standard was followed. Features not covered by this standard, shall be handled in accordance with sound engineering judgment to the satisfaction of the authority having jurisdiction.
1.4 Definitions ADA accessible: Describes a site, building, facility, or portion thereof that complies with ADAAG (Americans with Disabilities Act Accessibility Guidelines). approved: The word“approved” means“approved by the authority having jurisdiction”. atte ndant: The individual assigned to particular duties or functions in the operation of a funicular (also see 1 .4- supervisor).ANSI B77.2 pdf download.
