International meeting of technical supervisory authorities

from Wikipedia, the free encyclopedia

The International Conference of Technical Supervisory Authorities (ITTAB) is an annual conference of representatives of technical authorities and experts from many countries around the world to exchange experiences and increase the safety of cable cars. The first conference took place in 1950.

Members

Membership in the conference is open. The “cable car” countries Andorra , Argentina , China , Germany , Finland , France , Italy , Japan , Canada , Columbia , Norway , Austria , Poland , Portugal , Romania , Russia , Sweden , Switzerland , Singapore , Slovakia regularly take part in the conferences , Slovenia , Spain , South Korea , the Czech Republic , Hungary and the USA . These states together have over 95% of the world's installed and operated cable car systems.

Non-participating “cable car” countries are: Armenia , Australia , Bosnia-Herzegovina , Bulgaria , Chile , Georgia , India , New Zealand , South Africa , Turkey and Ukraine . Together, these do not account for 5% of all cable car systems installed worldwide.

Meetings

The ITTAB conferences are each organized by a host country. The 63rd conference from September 9-14, 2013 took place for the first time in Asia, in China in Xi'an , the capital of Shaanxi Province .

statistics

The countries working on ITTAB voluntarily provide statistical data on the respective previous year of operation. These are:

  • Number and system of cable cars
  • Number of passengers carried on each cable car system
  • Number of incidents and accidents on each cable car system
  • Number of people who were injured or killed in an accident, separated into passengers, operating personnel and third parties for each cable car system
  • Course of events and causes of the events and accidents or the description of the process.

Overview of promotions 2002–2011

The following information is based on the data made available to ITTAB by the participating countries (rounded):

in billions of cases Number of cable cars
2002 3.96 21,000
2003 3.79 19,000
2004 3.33 20,400
2005 3.28 22,000
2006 2.99 22,100
2007 2.87 22,300
2008 3.45 22,000
2009 3.96 21,000
2010 3.23 17,000
2011 3.48 21,000

Larger deviations in the number of cable car systems and transport cases in each year result from the fact that the data from some member states are occasionally missing. So has z. For example, the USA did not report any data to ITTAB in 2010.

Overview of transports worldwide compared to Austria

The following table uses the data from ITTAB to provide an overview of the number and type of cable cars and the people transported with them that were transported in Austria and worldwide (including Austria) in 2011.

Type of cable cars Number in Austria Transport in Austria Number worldwide Worldwide transport
Funiculars 21st 11,690 251 99,772
Two cable cars shuttle service 52 15,532 754 174,290
Two cable cars circulating 9 6946 29 9615
Monocable gondola lifts EUB 252 160.159 899 433.163
Combined lifts 9 7712 45 30,719
detachable chairlifts 378 262,789 1961 826.761
fixed-grip chairlifts 354 108,482 4888 647.744
Drag lifts 1914 156,660 12,041 969.443
Special tracks 223 292.964
total 2989 729.970 21.091 3,484,471

Several derivations can be generated from the data collected by ITTAB, some of which are reproduced in this table, including:

  • Austria has the most transports per year for cable cars worldwide,
  • Austria has the most detachable chairlifts worldwide (378),
  • Austria has the most gondola lifts in the world (252),
  • Japan has the largest number of fixed-grip chairlifts (1870), more than three times as many as the USA, which is in second place (545), Austria only has a modest 354,
  • France has the most T-bar lifts (2504).

If the special railways are disregarded, the table shows:

  • In Austria, the most transports are carried out for each type of cable car
  • worldwide and also in Austria, the transport of passengers to surface lifts is lowest in relation to the number of systems (Austria 81,850 and 80,512 people / system / year worldwide), which basically implies a low attractiveness of this type of system. Nevertheless, worldwide and also in Austria, the T-bar lifts are proportionately the most used cable car systems (Austria: 64% of the cable car systems are T-bar lifts; 57% worldwide),
  • Special ropeways are responsible for the largest number of passenger transports worldwide per facility and year (1,313,740), while these facilities play no role in Austria (or are classified in the other types of facility).
  • Circular double cable cars transport more than 57% more people / system and year in Austria (771,778) than worldwide (331,552),
  • Fixed-grip chairlifts carry only 29% of passengers in Austria, compared to 71% of detachable chairlifts. Also worldwide in 1961 detachable systems around 56% of passengers are carried and 44% with fixed clamps.
  • the ratio between fixed-grip chairlifts and detachable lifts is 2.5: 1 worldwide, in Austria 1: 0.9 (there are more detachable systems than fixed-grip lifts in Austria, and vice versa worldwide).
  • Combined installations have the best utilization in Austria with 856,889 passengers / plant / year. Also worldwide with 682,644 passengers / facility / year (if the special railways are not taken into account), the combined railways have the best utilization.
