The Ingersoll Rand CR-30 Static Smooth Drum Roller is a robust compaction machine powered by a 44 hp Kubota engine. It features a 52-inch wide, 29-inch diameter smooth drum with a nominal shell thickness of 0.47 inches, designed for effective soil and asphalt compaction. The drum vibrates at a frequency of 4,000 vibrations per minute (vpm) with an amplitude of 0.013 inches (0.34 mm), optimizing the compaction force applied. The roller has an overall length of 101 inches and a width of 56.4 inches, with a drum-to-tire base of 67.9 inches. Its height to the top of the Roll-Over Protective Structure (ROPS) measures 99.5 inches. The operating weight is approximately 5,732 pounds (2,600 kg), and the shipping weight is about 6,054 pounds. This balanced combination of size, weight, and vibration parameters makes the CR-30 suitable for medium-scale earthwork and paving projects where smooth, uniform compaction is required. Its compact dimensions and Kubota engine ensure reliable performance and maneuverability on various job sites.
