AIRLINE: Hello, all! I'm writing another story for GSE Today (www.gsetoday.com) on the wheels used in airport/airline ground support equipment. I am asking for users and experts for their experiences noting which type of wheels on say, an air start, or GPU, or water cart and which work the best. For example, in my experience at America West, they had baggage carts that employed hard-plastic wheels and inflatable rubber wheels. I believe the rubber offered a smoother ride, but would render the cart useless if a tire was deflated by a nail or spike on the ramp. Yet, if I worked with equipment in an area that might be constantly wet, or have a wet chemical that coated the floor, I might argue that a hard plastic or metal wheel might be better. Am I making my point clearly? Any comments will be greatly appreciated. Thanks, Mike Burris Cambridge, Massachusetts _______________________________ Do you Yahoo!?
