Why can't cranes, bulldozers, and the like run too fast? Too far?
Don't run too fast: the engine doesn't lift; you can't run too far: the tank isn't big enough.
Because it is tracked, easy to crush the pavement, are generally used to transport flat car
Several crane truck crane, maximum speed can reach 80 step, crawler cranes and bulldozers (basically all tracked) are generally in the non road walk (not on the road), such as the site on the beach, so there is no need to design the speed too fast. Not to say that the track can not speed, which there are cost reasons, in fact, foreign tanks can reach about 70 meters.
