jellybean said:The tri-axles were suppossed to compensate for getting rid of all the screws around 1985. The 3 axles originally were furthur forward with a long overhang to the rear. This was going to allow us to still gross 80,000lbs while only running single axle tractors. They had drop down legs on the rear to lower when at a dock for stabilization. However the powers that be didn't figure that if they were loaded with too much weight to the rear, you couldn't control them in bad weather because it would take to much weight off your drive axle. Therefore all the axles were moved back about 3-4 ft and became the joke of the fleet. In my useless opinion they should remove the front axle and retro-fit with overhead doors. Then retire them into the city as 45ft peddle vans.
Those tri-axles must have been a joy to turn around in a tight yard. All these tires dragging as you spun around must have really pulled the tractor back
