in the past when ALE couldn’t find a truck to match their exacting specifications, they simply designed and built their own, the Trojan.
When they realized they were hampered by load ratings on roads and bridges, they created an expanding trailer, one that could widen its wheelbase even when loaded. This decreases ground pressure therefore allowing the loads to travel over weakened bridges. Cutting down planning , travel time, decreasing environmental effects and reducing the inconvenience to the motoring public. Another amazing innovation from the ALE engineering team
