ANSI B77.2:2020 pdf download.Funiculars一Safety Requirements.
This document establishes a standard for the design, manufacture, construction, operation, and maintenance of funiculars for passenger transport.
Funiculars typically have the following characteristics:
— carrier capacity over 20 passengers;
maximum operating speed oer 300 feet per minute (1.5 meters per second);
— complex guideway that may contain curses, variable inclinations and a passing zone;
direct operator superision.
There are other types of transportation systems that utilize similar characteristics such as Incline Elevators (see ASME A17), Automated People Movers (see ASCE 40193), etc. The authority haAng jurisdiction, using information from the manufacturer and owner, shall specify any or all pro’Asions of this standard that apply to the funicular.
1.2 Purpose
The purpose of this standard is to delop 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 adoption by goernment 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. 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 improments in productiAty, efficiency, deelopment, and progress consistent with the objectres.
Such a system with these stated objecties constitutes a safety standard.
1.2.1 Otherclassifications
Funicular configurations that do not fall within the definition specified in 1.4- funicular, but fall within the general category of funiculars should be eluated by the authority haAng jurisdiction based upon the design engineer’s specifications and the applicable proAsions of this standard.
1.2.2 New materials and methodsforfuniculars
Adoption of technological improements in materials and adnces 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 coered by this standard, those materials, methods, or both, shall be clearly identified. Complete design and test information shall be proAded to the purchaser or the owner and the authority haAng jurisdiction (see 1.4— aut hority having jurisdiction).
1.2.3 Exceptions
Strict application of the proAsions of this standard may not be appropriate in e.ery instance. Whereer may be proposed to depart from the proAsions of this standard, the authority haAng jurisdiction may grant exceptions from the literal requirements or permit the use of other devices or methods that provide features comparable to those included in ANSI B77.2.ANSI B77.2 pdf download.
