18、eproduction or networking permitted without license from IHS-,-,-iiiForeword (This foreword is not part of American National Standard ANSI B77.1-2011.)This standard deals with passenger transportation systems that use cables, ropes, orother flexible elements for power transmission in the system. The

19、se systems includeaerial tramways, detachable and fixed grip aerial lifts, surface lifts, tows, and convey-ors.This standard is a revision of American National Standard for Passenger Ropeways -Aerial Tramways Aerial Lifts, Surface Lifts, Tows and Conveyors - Safety require-ments, ANSI B77.1-2006. Se

20、ction 1 provides the scope and general definitions forsystems covered in this standard. Sections 2 through 7 cover the specific passengertransportation types. Six (6) Normative Annexes and three (3) Informative Annexesare included in the standard. Normative Annexes are considered part of the standar

21、d.Informative Annexes are presented for the information provided and are not consid-ered part of this standard.The B77 standard had its inception in 1956. At that time, the industry dealings withrecreational passenger transportation had reached such proportions that safeguardswere required for the p

22、rotection of the public and progress of the industry. At the re-quest of the Eastern Ski Area Operators Association, one of the original sponsors ofthe project, a general conference was held in New York City. As a result of that con-ference, the American National Standards Committee B77, composed of

23、 operators,users, authorities having jurisdiction, designers, and manufacturers of aerial passen-ger tramways, was established to develop safety requirements. The first standardwas approved by ANSI on June 8, 1960, and revisions were developed and ap-proved in 1970, 1973, 1976, 1982, 1990, 1992, 199

24、9, and 2006.Because of the diverse nature of the industries that may use this standard, it is rec-ommended that authorities having jurisdiction consider an effective date of one yearfrom the approval date of the standard. The “effective date“ of this standard is a crite-rion selected by the committe

25、e and not by the American National Standards Institute.Suggestions for the improvement of this standard will be welcome. They should besent to the ASC B77, c/o National Ski Areas Association, 133 South Van GordonStreet, Suite 300, Lakewood, CO 80228 or e-mailed to ascb77nsaa.org.This standard was ap

26、proved for submittal to ANSI by the Accredited Standards Com-mittee (ASC) B77 on Aerial Passenger Ropeways. Committee approval of the stan-dard does not necessarily imply that all the committee members voted for itsapproval or the approval of every requirement in the standard. At the time this stan-

27、dard was approved, the ASC B77 Committee had the following members:Maynard Russell*, MCR Services LLC, Chairman Sid Roslund*, National Ski Areas Association, Committee AdministratorOrganization Represented Name of RepresentativeAerial Engineering John Ellis, P.E.All Ski Lifts Larry Wollum *Alta Ski

34、 develop a system of principles, specifications, and performance criteria that will meet the following objectives: a) reflect the current state-of-the-art in passenger ropeway design, operation, and maintenance; b) be acceptable for adoption by government agencies and others. It is recognized that c

35、ertain 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 approaching, loading, riding, unloading, and departing from passenger ropeways. This system is intended to resu

36、lt in passenger ropeways that are designed, constructed, operated, and maintained in a manner that helps reduce danger and exposure to risk to passengers and maintenance and operational personnel, and to encourage improvements in productivity, efficiency, development, and progress consistent with th

37、e objectives. Such a system with these stated objectives constitutes a safety standard. 1.2.1 Other ropeway classifications Passenger ropeway configurations that do not fall within the categories specified in 1.1, but fall within the general category of passenger ropeways, should be evaluated by the

38、 authority having jurisdiction based upon the design engineers specifications and the applicable provisions of this standard. 1.2.2 New materials and methods for passenger ropeways Adoption of technological improvements in materials and advances in techniques is essential to enable the industry to k

39、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, and complete design and test information shall be provided to the purchaser or owner and the authority having juris

40、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

41、e literal requirements or permit the use of other devices or methods that provide features comparable to those included in this standard. 1.2.4 Installations 1.2.4.1 Existing installations Existing installations and those with design review completed by the authority having jurisdiction prior to the

42、 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

43、the operation and maintenance subsection (2.3, 3.3, 4.3, 5.3, 6.3, 7.3) and normative Annexes A , D and F. NOTE Additionally, items listed under (2.3.1.1, 3.3.1.1, 4.3.1.1, 5.3.1.1, 6.3.1.1) are considered of special importance. Compliance on ropeways with design review prior to this standard shall

44、be required.

45、ed as new installations (see 1.2.4.3). 1.2.4.3 New installations New installations and those with 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 Ropeway modifications A

46、ropeway modification shall be defined as an alteration of the current design of the ropeway which results in: a) a change in the design speed of the system; b) a change in the rated capacity by changing the number of carriers, spacing of carriers, or load capacity of the carrier; c) a change in the

47、path of the rope; d) any change in the type of brakes and/or backstop devices or components thereof; e) a change in the structural arrangements; f) a change in power or type of prime mover or evacuation power unit; g) a change of the control system logic. Modified ropeways shall be inspected and/or

48、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 is required, such requests should be referred to t
