Caterpillar stretched its 740 articulated dump truck to 43.5 tons, the biggest payload among 40-ton-class ADTs. The body accommodates 31.4 cubic yards. A Cat C15 ACERT engine delivers 453 net horsepower and meets Tier 3 emissions limits without exhaust gas recirculation. The Cat-designed oil-over-nitrogen front suspension oscillates plus and minus 6 degrees, allowing the operator to travel at speed over rough terrain. Cat says its latest rear suspension blocks and mounts last as much as five times longer than previous designs. Differential locks with oil-cooled clutches can be engaged and disengaged on-the-roll. The 740 comes equipped with Cat Product Link factory installed to report location and machine-operating information wirelessly from remote work sites.
