Note(s)

The term "railway systems" is to be understood as covering:

  1. systems in which trains or individual passenger vehicles or load carriers run on, or are guided by, ground or elevated tracks defined by rails, ropes, cables, or other guiding elements for wheels, rollers, or sliding anti-friction devices (permanently attached to a continuous traction element B65G 17/00);
  2. systems in which carriers or impellers for persons or loads are attached to, e.g. suspended from, a guided traction rope or cable which determines their path of movement (chain conveyers, scraper conveyers B65G 17/00, B65G 19/00);
  3. "power and free" systems of either of the above types in which vehicles, load-carriers, or loads may be selectively coupled to, or uncoupled from, continuous traction members, e.g. cables, chains.

 B61B
RAILWAY SYSTEMS; EQUIPMENT THEREFOR NOT OTHERWISE PROVIDED FOR (inclined systems in, or associated with, buildings or other structures and serving as lifts or hoists for conveying passengers or other loads from one level to another, e.g. inclined lifts associated with stairways, B66B; travelling cranes B66C)
 B61B

Note(s)

The term "rope railways" is to be unterstood as covering railways using cables or chains as traction or suspension means. Within the scope of this sub-class, the words "ropes", "cables", or "chains" are to be regarded as equivalent unless specifically mentioned. [2]
