Respectable diagram of the major points on a standard tractor trailer truck (or articulated lorry, if you happen to be from the other end of the pond).

The WABCO 3200 was a rare example of a tri-axle haul truck configuration A medium sized haul truck, the 214-short-ton (194 t; 191-long-ton) Caterpillar 789 [1]. Most haul trucks have a two-axle design, but two well-known models from the 1970s, the 350T Terex Titan and 235T WABCO 3200/B, had three axles.
It is the largest articulated haul truck offered by Caterpillar; larger trucks use a rigid frame system. The ejector uses a 4-cylinder hydraulic ram and blade to dump the material out, a similar system to Cat's wheel tractor-scrapers.
A size 55/80R63 radial tire was developed by Michelin in conjunction with Caterpillar specifically for the first generation 797. [16] The Caterpillar 797B and 797F run 4.028 m (13.22 ft) tall, 5,300 kg (11,680 lb) Michelin 59/80R63 XDR. Most first generation 797s have been retrofitted to use the 59/80R63 tires as well. [17]
