The magneto-inductive cable testThe cable is the most important structural element of the aerial railway. The travelling through the running gear, over rollers, round pinions and steering wheels, at a constant high tension, and the influence of the weather subject the cables to a perpetual wear and tear. For this reason they have to be periodically examined for possible damage.The wirebreak is the most frequent cable damage. Others are notches, pressure points, tears, corrosion and parts affected by lightning. Damage can be on the surface of the cable as well in the interior parts.Damaged cable = weakened cableGovernement regulations require therefore a periodic magneto-inductive cable test.In this disturbance-free method of examination the cable is locally magnetized and the differentiated formed magnetic field is abstracted by inductance. The electrical tensions arising thereby are visually recorded as a continuous diagram.

Ferryboat “Vogel Gryff” of the Basel Klingental Ferry Service, built 1962From Greater- to Lesser-Basel by ShipThe history of the Basel ferry, unlike that of its bridges, only goes back to the 19th century. The first ferry commuted between Harzgraben and Waisenhaus from 1854 until the opening of the Wettstein Bridge in 1877. From 1877, the Münster ferry, a little further downstream, was in operation, and in 1862 there was a ferry service between Totentanz and Kaserne. Under the name “Klingental Ferry” it is still working today, a “flying bridge for pedestrians”, as the ferries were described in a pilot project of 1848. The youngest of the three present-day Basel ferries, the St Alban ferry, dates from 1894. In 1944 on the initiative of the then director of the Basel Tourist Office, the three ferryboats were given the names of the heraldic figures from the three Lesser-Basel honorary companies. From downstream on, they are “Wilde Ma” (St Alban), “Leu” (Münster) and “Vogel Gryff” for the Klingental ferry. Until 1954 the three ferries were run by the Basel Cultural Society – the Basel Art Gallery was financed from the proceeds. Subsequently the Cultural Society donated these ships to the ferrymen who had manned them. In 1972 the Klingental ferry, and in 1976 the St Alban ferry, came into the hands of a foundation which appointed lessees, while the Münster ferry is still today in private ownership. In 1977 the “Wilde Ma” and in 1983 “Vogel Gryff” were replaced by new ships with the same name. The old “Vogel Gryff” now has a place of honour in the Transport Museum.

Aerial cableway mast with two circulating gondolas, 2016One means of transport conquers the AlpsThe mast is equipped with articulated, cable-bearing sheave assemblies (arrays of grooved wheels). It also carries elements needed for its maintenance (e.g. the transverse struts) and to ensure the safety of those working on it. Usually, the cable passes over the sheave assemblies, which support the load. However, where a mast has to keep a cable down rather than up, the cable is made to pass beneath the sheave assemblies. Also possible are so-called compression assemblies that fulfil both roles.After 30 years of evolution, CWA’s fourth generation of Omega gondola with its ideal shape is seen by many as an industry standard. In 2015 gondolas could be found in over 60 countries – and increasingly in urban environments. Gondola development in Switzerland in terms of engineering know-how is focused on optimised aluminium profiles and connection technology.

Aérospatiale SA 315B Lama helicopter HB-ZGP, France 1974Flying workhorseThe multi-purpose SA 315B helicopter by the French aerospace manufacturer Aérospatiale (formerly Sud Aviation) is based on the familiar Alouette II, though better suited to mountainous terrain thanks to its more powerful turbine. It was originally developed for the Indian Army. Its inaugural flight was in 1969. The aircraft is considered exceptionally reliable mechanically. Altogether more than 80 Lamas have been registered in Switzerland, although the number in active service as of March 2018 stands at 15.In 41 years of service, this particular example, built in 1974, worked over 24,000 flying hours in France, Bolivia and (from May 2005) Switzerland. That is a record for this type of helicopter in our country. This Lama was most recently in service with Alpinlift Helikopter AG in Buochs. Its missions in the often underrated realm of aerial transport included construction and installation projects in poorly accessible terrain, forestry work, providing alpine herdsmen and mountain refuges with supplies, and firefighting.
