CATERPILLAR CD8 - SPLIT DRUM STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CD8 Split Drum Smooth Drum Roller is a versatile compaction machine designed for efficient soil and asphalt compaction. It features an 8-ton operating weight with a maximum of 20,834 lbs (9,450 kg) with cab, delivering a static linear load of 146 lbs/in (27.9 kg/cm). The unit is powered by a Cat C3.4B engine with ACERT technology, providing 100 hp (75 kW) while complying with Tier 4 Interim and Stage IIIB emissions standards. Its drum system includes tandem vibratory drums, each 59 inches (1500 mm) wide, with a drum offset of 51 inches (1320 mm), allowing a maximum compaction width of 111 inches (2820 mm). The roller offers independent vibration control per drum with centrifugal forces ranging from 13,309 lbs (59.2 kN) to 16,590 lbs (73.8 kN), enhancing compaction precision. Eco-mode operation, oil-bath lubrication, and extended vibration service intervals optimize fuel efficiency and reduce maintenance costs. The machine's dimensions are 13.9 ft (4284 mm) in overall length, 5.5 ft (1676 mm) in width, and 115.2 inches (2926 mm) in height to the top of ROPS/FOPS, with a 10.3 ft (3139 mm) wheelbase. Maximum travel speed reaches 7.5 mph (11 kph), with a fuel tank capacity of 36 gallons (136 liters) and a water spray tank of 159 gallons (602 liters) to facilitate surface moisture control during compaction. Articulation angle is 25 degrees, and steering radius inside is 9 ft 3 in (2.9 m), allowing excellent maneuverability on varied job sites. The split drum design improves soil compaction consistency and adaptability in diverse applications.
