Goldhofer to present its self-propelled trailer at ConExpo

Goldhofer will be presenting its six-axle ADDrive with three self-propelled axle lines, at ConExpo in Las Vegas this March 7-11.

ADDrive has a wide range of potential applications. The switchable drive, which was unveiled at Bauma in Munich, optimizes working with heavy-duty modules – whether they are operated as towed modules or as self-propelled modular transporters. That obviously means greater efficiency in terms of fleet management, since ADDrive offers greater flexibility and improved economics.

The attractions of the system include efficient vehicle mobilization and fast and easy reduction of the overall weight, for example when bridges have to be crossed. In such cases the tractor is simply disconnected and ADDrive switched to the self-propelled mode. That avoids the need to unload the cargo onto a separate self-propelled module. In addition to solving problems with weight limits on bridges, this solution is equally applicable to tricky situations involving tight bends, serpentine roads and roundabouts.

Goldhofer’s engineers have designed the ADDrive with a free-wheeling mode: as soon as a certain speed has been reached, the system disconnects automatically from the drive and functions as a normal heavy-duty module for towing at speeds of up to 80km/h. With the drive axle uncoupled from the motor, there is no more oil flow. That means there can be no overheating of the drive, and – with the related sources of wear and resistance eliminated – it significantly reduces maintenance.

Another big advantage is that if a hillclimb calls for a short-term increase in available power, ADDrive is simply reactivated by pressing a button. In some cases that avoids the need to have a second tractor in attendance. And it is especially safe: ADDrive is the world’s first heavy-duty module to have a particularly quick-acting electronic braking system.

Goldhofer will be at Stand G-4416
