Prevedi caterpillar track na: francuski
Trade name for an endless flexible belt of metal plates on which certain vehicles such as tanks and bulldozers run, which takes the place of ordinary tyred wheels and improves performance on wet or uneven surfaces.
A track-laying vehicle has a track on each side, and its engine drives small cogwheels that run along the top of the track in contact with the ground. The advantage of such tracks over wheels is that they distribute the vehicle's weight over a wider area and are thus ideal for use on soft and waterlogged as well as rough and rocky ground.
