Em 1963, a Caterpillar introduziu o 769, um caminão revolucionário construído especificamente para os trabalhos mais rigorosos da mineração e da construção. Cinquenta anos depois, os nossos camiões continuam melhores. Tirámos o melhor de nossa herança e combinámos isso com tecnologias que ajudam nosso os seus operadores mais produtivos e melhoram drasticamente a economia de sua frota de transporte. Este 772G tem um sistema de controlo de tração atualizado para mantê-lo em movimento quando as condições do solo não são perfeitas. Verá melhorias no uso de combustível e estamos a tornar a experiência do operacional cada vez melhores, reduzindo as condições de ruído e atualizações constantes da cabine. A herança e o novo uso da tecnologia são combinadas neste caminão para uma finalidade - o sucesso contínuo de seus negócios.
