Trucking milestones: 1979 – hard work for the NG 2632/6x6

Series: Trucking milestones

Breathing new life into the Gotthard.

At the end of the 1970s, Mercedes‑Benz delivered the ventilators for the fourth-longest tunnel in the world.

The specially constructed trailer also served as a mounting platform.


Hands up! Who’s been through it before – the most important Swiss corridor through the Alps, the Gotthard Tunnel? The fourth-longest tunnel in the world and longest in Switzerland is an impressive 16.9 kilometres. Building work took ten whole years to complete and the tunnel was then opened on 5 September 1980.

However, as impressive as the drive is, every driver is pretty relieved to see daylight at the other end of the tunnel again. You’ve got to persevere and keep calm until you get there.


More than 20 ventilators provide fresh air in the tunnel, which were transported to the construction site with Mercedes‑Benz at the end of the 1970s. The gigantic units were between 16 and 28 tonnes in weight and in some cases six metres long. The largest ventilator had a diameter of almost four metres.

As a towing vehicle, an NG 2632/6x6 managed the heavy-haulage load and an NG 1932 was used for pushing. Because the whole convoy weighed in at 95 tonnes and was 38 metres long.

And those are the hard facts. Now you have a little story up your sleeve for when you have your next break at a service station around the Gotthard and run into fellow truckers.
