| has gloss | eng: Continuous tracks are large (modular) tracks used on crawler-type tanks, construction equipment and certain other off-road vehicles. Unlike the Kégresse tracks which use a flexible belt, most continuous tracks are made of a number of rigid units that are joined to each other. The tracks help the vehicle to distribute its weight more evenly over a larger surface area than wheels can. Tracks do this because as the tracked vehicle moves forward the segments are laid out flat on the ground at the front and are picked up again at the back. The segments in between the front and the back end carry load too as they are supported by rollers. This keeps it from sinking in areas where wheeled vehicles of the same weight would sink. The seventy-ton M1 Abrams tank has an average ground pressure of just over . Since tire air pressure is approximately equal to average ground pressure, a typical car will have an average ground pressure of to . |
