2、.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Consensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has

3、been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and objections be considered, and that a concerted effort be madetowards their resolution.The use of American Nation

There are other t

26、ypes of transportation systems that utilize similar characteristics such as Incline Elevators (see ASME A17), Automated People Movers (see ASCE 40193), etc. The authority having jurisdiction, using information from the manufacturer and owner, shall specify any or all provisions of this standard that

27、 apply to the funicular. 1.2 Purpose The purpose of this standard is to develop a system of principles, specifications, and performance criteria that will meet the following objectives: a) reflect current state-of-the-art for funicular design, operation, and maintenance; b) be acceptable for adoptio

28、n by government agencies and others. 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.

29、 This system is intended to result in funiculars that are designed, constructed, operated, and maintained in a manner that helps reduce danger, exposure to risk to passengers and maintenance and operational personnel, and to encourage improvements in productivity, efficiency, development, and progre

30、ss 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 evaluate

31、d by the authority having jurisdiction based upon the design engineers 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 k

32、eep 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 juris

33、diction (see 1.4 authority having jurisdiction). 1.2.3 Exceptions Strict application of the provisions of this standard may not be appropriate in every instance. Wherever it may be proposed to depart from the provisions of this standard, the authority having jurisdiction may grant exceptions from th

34、e literal requirements or permit the use of other devices or methods that provide features comparable to those included in this standard. ANSI B77.2-2014 2 1.2.4 Installations 1.2.4.1 Existing installations Existing installations, and those with design review completed by the authority having jurisd

35、iction 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 includ

36、ed 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 inst

37、allations 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. 1.2.4.4 Modifications A modification shall be defined as an alteration of the curre

38、nt design of the funicular that results in any of the following: a) a change that increases the design speed of the system; b) a change in the rated capacity by changing the number of carriers, load capacity of the carriers, or a change in weight or carrier size; c) a change in the path of the rope

39、or guideway; d) a change in the type of brakes and devices or components thereof; e) a change in the structural arrangements; f) a change in energy source or type of power unit, evacuation power unit or alternate carrier unloading system (used in evacuations); g) a change of the control system logic

40、. Modified funiculars shall be inspected and/or tested to assure compliance with the modified design. Test procedures and inspection criteria shall be provided by the designer or manufacturer. 1.2.5 Interpretation of standard In cases where additional explanation or interpretation of this standard i

41、s required, such requests should be referred to Accredited Standards Committee (ASC) B77, c/o National Ski Areas Association, 133 South Van Gordon Street, Suite 300, Lakewood, CO 80228-1706 or e-mail ascb77nsaa.org. 1.3 Reference to other codes and standards The design, installation, operation, and

42、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 stres

43、ses, 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 hav

44、ing 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”. attendant: The individu

45、al assigned to particular duties or functions in the operation of a funicular (also see 1.4 supervisor). authority having jurisdiction: The phrase “authority having jurisdiction” means any government agency empowered to oversee the design, manufacture, construction, operation, maintenance, and use o

46、f funiculars. Where no such agency exists, the owner of the funicular shall be considered the authority having jurisdiction. auxiliary power unit (APU): Generic term to generally describe a gas or diesel engine generally used as a backup to the prime mover. It can be designated as a prime mover or e

47、vacuation power unit depending upon use and configuration. barrier: A device or object that provides a physical boundary to a hazard. Basic Life Support (BLS): Medically accepted non-invasive procedures used to sustain life. brake: A device consisting of one or more friction devices which if applied

48、, accomplishes braking. braking: The process of absorbing energy in order to maintain or reduce the speed of the funicular. NOTE The typical resistances effective in absorbing the energy of a funicular include: a) the inherent resistance in the system (e.g., friction); b) incidental resistance (e.g.

49、, slope, gravity, wind); c) applied resistance (e.g., brake, power unit regeneration). buffer: A device placed at the end of the carrier guideway, or installed on the carrier as an energy absorbing device in the event of overtravel.
