CATERPILLAR CS531C STATIC SMOOTH DRUM ROLLER

Technical Description

The Caterpillar CS531C is a vibratory smooth drum roller designed for efficient soil and asphalt compaction in construction and road building applications. It features an 83.9-inch wide smooth steel drum with a 96-inch diameter, providing a broad compaction width and consistent surface finish. The roller delivers a maximum centrifugal force of 24,060 lbs at a vibration frequency of 30 vpm, with a medium-low setting of 12,030 lbs, allowing operators to match compaction effort to job requirements. It is powered by a Caterpillar 3116T inline-six turbocharged diesel engine with a displacement of 402.8 cu in (6.6 L), producing 145 hp (108 kW) of gross power for reliable performance in demanding conditions. The CS531C has an operating weight of 20,503 lbs, contributing to high static and dynamic compaction force. It is equipped with 23.1X26-8 ply tires and offers a top travel speed of 8 mph (13 km/h) for good site mobility. The machine has an overall length of 17.3 ft, width of 8 ft, and a top-of-cab height of 8.3 ft, with 19.1 inches of ground clearance and a 9 ft wheelbase for stability on uneven terrain. Operating capacities include a 58.2-gallon fuel tank, 29.1 gallons for the hydraulic system, and 5.3 gallons for engine oil, supporting extended work cycles with reduced downtime for servicing.
