At Conexpo stand G-4416, Goldhofer will be presenting its two big attractions to its American customers: a 6-axle ADDRIVE with three self propelled axle lines and an STZ-P 9 (3+3+3) AA low loader semitrailer for use on North American highways.
ADDRIVE is something special: With its enormous versatility and wide range of potential applications, this 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 80 km/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: If a hill climb 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 (EBS).
For years, the semitrailers in Goldhofer’s STZ-P series have proven themselves as reliable partners in the heavy haulage industry. With swing-axle technology, maximum frame strength and extendible decks plus a choice of vehicle widths and various wheelbases, these semi lowloaders set the standard. The STZ-P 9 (3+3+3) AA is also extendible between the bogies to comply with US regulations regarding axle spacing. As an additional advantage, the rear bogie can be retracted under load for greater flexibility when negotiating tight bends and roundabouts. On completion of the maneuver, the tractor is then used to return the vehicle to the original length.
At Conexpo, Goldhofer will also be showing its THP/DC Dual Lane solution, which has now reached the production stage. It is designed to permit the deck to be widened hydraulically while under load.
