Before IC Bus products get to carry the world’s most precious cargo, they are subjected to brutal testing in Melrose Park, Ill., at Navistar’s own state-of-the-art quality testing facility, ensuring that our buses run safer than any other vehicle on the road.
When your job is to safely transport kids to and from school, there is no margin for error. That means there can be no inch left uninspected on the vehicles that carry them. IC Bus products are pushed beyond their limits at Navistar’s own state-of-the-art quality testing facility in Melrose Park, Ill.
In the Body Lab, buses are pounded and pulverized to ensure that they not only meet federal strength and safety standards, but exceed them. The rear of every seat is battered with a striker that’s four inches in diameter, making sure it will sustain a standard amount of force and protect a passenger from the knees to the head.
Each vehicle is subjected to a roof-crush test with a simulated driver wired with devices to monitor the amount of energy a human would receive during a real accident. The buses are even chained to the floor and subjected to a full-frontal impact with an enormous 4,500-pound battering ram swung from a pendulum to test how it would react in a head-on collision on the open road.
In the Corrosion Lab, buses are doused with salt spray and sludge to ensure that IC Bus products resist corrosion and hold up against the tough winter climates that they face in the northern states and in Canada. In only six months, this test can simulate the effect of 10 years of hard usage, helping engineers develop coatings and materials that are the best at resisting all kinds of weather conditions.
They all come through with flying colors, because if they didn’t we wouldn’t allow students to climb on board.
