Lots of Choices – All Reliable.
A tandem vibratory roller has to get the required density, match the paver production and keep on working hour after hour, shift after shift. The vibratory systems on Cat® tandem vibratory rollers are designed to give you the options you need to match project requirements while providing worry-free operation.
Years of on-the-job research by Caterpillar point to the need for versatility on tandem vibratory rollers. The three Cat vibratory system options cover the entire range of compaction requirements. High frequency with lower amplitudes is available when high working speed is needed to match pavers operating at consistently high speeds. Low frequency with higher amplitudes can be selected when the primary requirement is high compaction energy to create density in thick, harsh mats.
Then, we add to the package the industry's best warranty—3000 hours. Cat vibratory systems hold up under extreme conditions because of the sealed pod design that is assembled in special "clean" rooms to prevent contamination in the oil bath lubrication. On some models, vibratory systems include the patented Cat eccentric weight design that is hollow and partially filled with steel shot. There is no possibility of introducing metal flakes into the bearing lube oil because there is no contact between moving counterweights. Save time and money by not having to rebuild vibratory drums that have failed bearings.
