Increased power, smoother cleaner operation, and lower noise levels are the result of the new 25 horsepower, cast iron three-cylinder, liquid-cooled diesel engine in the 2009 P33/24 Trench Roller. Marine grade “tinned” wiring, watertight automotive-type electrical connectors and case-hardened final drive gears and shafts are only a few of the standard features that update the reasonably priced P33/24 Trench Roller manufactured with traditional American ruggedness and reliability.
Twelve years of uncompromising design and rigorous fabrication standards at our USA manufacturing facility enables AMPAC to bring to market a proven sub-base compaction workhorse that delivers reliable performance with minimal downtime and optimal results project after project, year after year.
