The four-drum Cat 825K compactor incorporates Caterpillar’s Machine Drive Power (MDP) system that enables operators to consistently attain compaction specifications with minimal passes. Maximum operating weight is 78,326 pounds, and the Cat C15 ACERT engine delivers 405 net horsepower. The 3F/3R Cat power-shift transmission has Single Clutch Speed Shifting, which assists in maintaining torque flow through the transmission during gear changes.
Caterpillar’s MDP system measures the soil’s load-bearing strength to assess compaction. The system—which works efficiently with single- or four-drum configurations, smooth or padfoot—senses the rolling resistance of the material being compacted (the measure of its load-bearing strength) to determine the degree of compaction. MDP measurement technology is the foundation component of the comprehensive Cat Compaction Control system, which is scalable to meet a wide range of needs and applications. Mapping capability, with two levels of accuracy, enables the operator to easily monitor compaction progress and ensures that compaction is of uniformity quality. Compaction data can be downloaded or wirelessly transmitted to the online VisionLink® user interface for analysis and reporting, using a computer or mobile device. The overall system provides a means to attain optimum productivity, job quality, and profitability.
