New ANSI B77.1, Passenger Ropeways – Aerial Tramways, Aerial Lifts, Surface Lifts, Tows and Conveyors – Safety Requirements

Since we’ve finally got some snow up in the Sierras, it’s a good time to look the latest revision of ANSI B77.1, “Passenger Ropeways – Aerial Tramways, Aerial Lifts, Surface Lifts, Tows and Conveyors – Safety Requirements.”  Released in 2011 and editorially corrected in October, this standard deals with passenger transportation systems that use cables, ropes or other flexible elements for power transmission in the system. These systems include aerial tramways, detachable and fixed grip aerial lifts, surface lifts, tows, and conveyors.  It’s available now from Document Center Inc.

The B77 standard had its inception in 1956. At that time, the industry dealings with recreational passenger transportation had reached such proportions that safeguards were required for the protection of the public and progress of the industry.

At the request of the Eastern Ski Area Operators Association, one of the original sponsors of the project, a general conference was held in New York City. As a result of that conference, the American National Standards Committee B77, composed of operators, users, authorities having jurisdiction, designers, and manufacturers of aerial passenger tramways, was established to develop safety requirements.

The first ANSI B77.1 standard was approved on June 8, 1960, and revisions were developed and approved in 1970, 1973, 1976, 1982, 1990, 1992, 1999 and 2006.  The current standards developer is the National Ski Areas Association.
