<p>Figures 4,5 and 6 show the back of the truck unit in a few cases along with crawler tracks applied to the drive wheels. These help to navigate the truck on rough surfaces e.g. a road that is not paved, in the rain or a snow-covered road. For two different types of roads we can apply different treads of the crawler track that depends on specifics and its forced shape, which is necessary for the smooth movement in the abovementioned areas. <Figures 4, 5 and 6></p> |
