Tier 4-lnterim Engine

摘要

With a compaction width of 91 inches and a fully ballasted operating weight of 59,500 pounds, the Dynapac CP274 is powered by a 110-horsepower Cummins QSB 4.5 Tier 4-lnterim engine. A thermostatically controlled cooling fan lowers ambient noise, according to the company. A smooth start/stop system when changing direction helps mat quality. The company's dual-circuit braking system maintains full braking operations even if one circuit is disabled. The optional "air-on-the-run" system allows the operator to adjust the tire pressure during the compaction process. Another option, the DCA-A compaction analyzer, can play back the rolling pattern and produce a printout of information for later analysis.
