Heavy haulage using a bridge trailer


13/09/2018 | In early September Bau-Trans carried out two special transport jobs using a bridge trailer. Departing from Steinhaus close to Wels it transported two 86-tonne containers.

Preparations for the creation of a transport concept for the use of this special flatbed trailer took about half a year. “Due to an overall transport weight of some 250 tonnes, the bridge trailer had to be statically calculated. Secondly, because of its overall length of some 74 metres, a temporary motorway exit had to be updated as well,” Josef Ammann, the Department Manager for Heavy Haulage Transports explains the background of this special transport jobs carried out in cooperation with Felbermayr. The two storage containers weighed in at 86 tonnes each and sported a length of roughly 27 metres. They measured some four metres in diameter.

Thrust and tractor unit

Together with the bridge trailer and the tractor unit, the transport setup reached a total weight of a more than 200 tonnes. “Due to the inclines en route, the transports also required us to use a pusher unit,” Ammann reports. The tractor unit was a Mercedes Arocs 8x6 with 630 bhp, by the way. An MAN TGX 8x4 with 640 bhp pushed the unit.

The bridge trailer was used because of the containers’ length of 27 metres. Thanks to its special construction it can, for instance, be lifted about six feet and thus be pivoted on top of barriers and other obstacles if tight corner radii or roundabouts demand it. This is a process that rigidly constructed frames do not offer.
