DYNAPAC CA252/262 STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA252/262 static smooth drum roller is a robust compaction machine designed for medium to large-scale soil and asphalt applications. It features a wide 83.86-inch (2130 mm) smooth steel drum with a diameter of 60 inches (1523 mm) and a shell thickness of 0.98 inches (25 mm), providing a static linear load of approximately 155 lb/in (27.7 kg/cm). The total operating weight, including the Roll-Over Protective Structure (ROPS), is around 22,700 lb, with a maximum operating mass reaching up to 29,542 lb distributed between the front and rear modules at 13,007 lb and 9,700 lb, respectively. Powered by an engine delivering 125 hp at 2200 rpm, the roller achieves efficient compaction performance with a vibration frequency of 33 vibrations per minute (vpm) and a theoretical gradeability of 42%, allowing operation on steep slopes. The machine’s dimensions include an overall length of about 18.2 feet, width of 7.63 feet, and height of 9.75 feet with ROPS, or 7.18 feet without it. The drum is supported by vertical oscillation up to ±9°, enhancing ground conformity, and the rear axle uses a failsafe multidisc brake system for reliable stopping power. The fuel tank capacity is 66 gallons (250 liters), supporting extended operational periods. This roller is suitable for compaction of granular and semi-cohesive soils, providing strong static and vibration force for effective soil densification on highways, embankments, and other earthworks requiring uniform compaction and high productivity.
