GINAF contracted with DAF in 1982 to improve sales and service of the trucks, but remained an independent family business. In the following years, GINAF also made adaptations to many DAF chassis and regularly supported the Eindhoven-based company in the development of special models, such as the first DAF FAD 2800 (8x4) and the unique F 2800 MAG with underfloor engine, as well as its successor F 3300 MAG for super-volume transport. To keep pace with the construction industry, GINAF was among the first to introduce a five-axle truck, the F 520, in 1984, which was basically an 8x8 chassis with a fifth, non-driven axle in the center of the vehicle. The 13-ton front axle of this 10x8 chassis was also new. A total weight of 58 tons was now possible.
Another big step forward was the development of the Hydro-Pneumatic-Suspension-System (HPSS) in 1986, which made tipping much safer. Two years later, with the introduction of the F 535 (10x4) model, the Dutch truck manufacturer was the first to achieve the legal maximum weight of 50 tons. When DAF introduced its new 95 cab in 1987, GINAF incorporated it in modified form into the new G Series. Two years after that, GINAF produced the M-series, equipped with DAF's CF cab. GINAF decided not to use DAF's new XF long-haul cab, but simply put the smaller CF cab on its own chassis, since GINAF trucks were not suitable for long distances anyway.
Stronger and safer
An important innovation was the electronic steering system (EVS), which made the rear axle of a tandem unit steerable. It was also capable of carrying four tons more. The heaviest model was equipped with a DAF six-cylinder diesel with 480 hp coupled with a ZF 16-speed transmission. An Allison automatic was available as an option, as was an AS-Tronic AMT transmission.
In 2007, GINAF collaborated with DAF and ZF to develop AS-Tronic Dual Mode, which allowed the vehicle to switch automatically between on-road and off-road modes. In 1996 the front axle load was increased to 11.5 tons. Hence a four-axle chassis was able to reach the maximum gross vehicle weight of 46 tons that was permitted in the Netherlands. However, this led to a drop in demand for five-axle trucks. But even in the new X-series, which was presented at the Bedrijfsauto RAI show in 2002, GINAF continued to offer 10x4, 10x6 and 10x8 versions, in addition to chassis with 8x4, 8x6 and 8x8 drive configurations.
