Rubber tracks, however, make it possible for the excavator to move over hard surfaces, whilst still keeping the necessary off-road capability. Rubber tracks are one of the greatest late innovations in the continuous track area. For example, rubber tracks are now used not only in construction sites, but also when laying asphalt to prevent damage during road construction. Rubber excavator tracks can save a lot in transport costs, as no additional machinery is required to transport them. Rubber tracks are a top pick for a vast array of heavy vehicles, however, they work particularly good for mini excavators. Tracks made of rubber significantly increase the mobility of mini excavators, and let it handle more weight through the use of newest technologies. Furthermore, rubber tracks ensure a smoother ride, and are permitted to cross asphalt, hence they don't damage roads the way steel tracks do. There raises, however, a concern about rubber track durability.
