The Bison line of conventional aircraft tow tractors from Goldhofer features a modular design, allowing the vehicles to be easily adapted to market-specific requirements. As a result, the Bison is suitable for almost any aircraft type and weight class up to 880,000 pounds, such as the B747. The future-proof platform uses many identical parts throughout the Bison family to ensure an optimum spare part availability. The flexible ballasting concept allows for individual configuration. The minimalistic design reduces the number of parts to be maintained and ensures easy access to all important parts for maintenance, service and repair. The Bison line of tractors are available in diesel or electric models.
