Caterpillar's new B-Series articulated trucks include the 735B (36-ton payload), 740B (43.5-ton payload) and 740B EJ Ejector Body (42-ton payload). Body capacities (heaped) are 25.8, 31.4 and 30.2 cubic yards, respectively. The new Cat trucks use engines that are Tier 4-Interim certified and feature both a new traction-control system and a redesigned transmission. Coupled with the new drive-train technology is a redesigned operator's station that is engineered, says Caterpillar, to reduce driver effort and fatigue. All three new models use the 15.2-liter Cat C15 ACERT engine with respective gross-horsepower ratings of 452, 489 and 489. Along with Caterpillar's proprietary ACERT technology for electronically managing intake-air and fuel-injection systems, the C15 incorporates the Cat NOx Reduction System and Cat Clean Emissions Module (CEM), which includes a diesel paniculate filter. An "on-the-go" regeneration system (for cleaning accumulated soot from the filter), says Caterpillar, allows regeneration to take place without operator intervention and without interruption of the work cycle.
