In 1963, Cat a introdus modelul 769, un camion rigid revolutionar dedicat rigorilor specifice industriei miniere si de constructie. Cincizeci de ani mai tarziu, camioanele noastre sunt mai bune ca oricand. Am combinat robustetea si fiabilitatea traditionala cu tehnologii noi care contribuie la protejarea mediului nostru, la sporirea productivitatii operatorilor si care imbunatatesc semnificativ economia flotei noastre de transport. Modelul 772G este echipat cu un sistem de control al tractiunii imbunatatit care va permite sa lucrati chiar si atunci cand conditiile de teren nu sunt ideale; veti observa imbunatatiri in consumul de combustibil, datorita noilor functii adaptabile de economisire a carburantului, si va veti bucura de cea mai buna experienta de operare datorita transmisiei de calitate, nivelului redus de zgomot si cabinei modernizate. Constructia acestui camion imbina traditia cu noile tehnologii pentru un singur scop - succesul continuu al afacerii dvs.
