The Schopf ZH5 hybrid tractor achieves the often required speed of 30km/h even with heavy loads. This is important for coping with the increasingly shorter turnaround times of the airlines and also ensures that the tractors do not become an obstacle on the driveways, consequently saving time and money. In addition to maintenance and operation-specific changes, a measure to reduce fuel consumption was implemented for the ZH5. In maximum operation, at maximum engine power, the engine reduces the speed to a level that maintains the current driving state.
