Tag Axle
Just having one of those DAH! revalation moments. Recently looking at a bus and I became aware of the capability to raise the tag axle. Is this common on all buses? I have never heard anyone discuss this topic. Is it so basic that it just isn't mentioned. It seems to me that as simple as the principle it has the potential to be a safety issue if it should malfunction when cruising. How does one know that it is carying it's share of the load ? I assume this is for better maneuverability, tire scrub elimination. What are the trouble aspects of this mechanical system? Is this always, never, or sometimes by Prevost? Is it air or hydraulic actuation? Is there an alarm on the dash to warn against over the road drieving in the raised position? JIM
