Descrição

Em 1963, a Caterpillar introduziu o 769, um revolucionário camião construído especificamente para os trabalhos rigorosos da mineração e da construção pesada. Cinquenta anos depois, os nossos camiões continuam melhores. Usamos o melhor da nossa herança robusta e confiável e combinamos isso com tecnologias que ajudam o nosso meio ambiente. Tornam os operadores mais produtivos e melhoram drasticamente a economia de sua frota de transporte. O 770G possui um Sistema de Controle de Tração (TCS) atualizado para mantê-lo em movimento mesmo quando as condições do solo não são perfeitas. O Cliente verá consequentes melhorias por meio de economias de combustível novas e flexíveis. Estamos tornando a experiência operacional cada vez melhor, com mudanças na qualidade de condução, redução de ruído e atualizações da cabine. A herança e o novo uso da tecnologia são combinadas neste camião para uma finalidade – o sucesso contínuo de seus negócios.
