DYNAPAC CA251A STATIC SMOOTH DRUM ROLLER

Technical Description

The Dynapac CA251A is a static smooth drum roller designed for efficient compaction of asphalt, concrete, base, and sub-base courses. It features a robust Cummins engine delivering 107 hp at 2400 rpm, with an optional 152 hp engine variant. The machine boasts an 84-inch wide drum and an operating width of 93 inches, facilitating wide-area compaction. The drum vibrates at a frequency of 2700 vibrations per minute, enabling effective density improvement on roadways, airfields, and dams. Its turning radius inside measures 148 inches, supporting precise maneuverability. The CA251A has an operating mass of approximately 22,820 lbs (10,400 kg), balanced to provide optimal ground contact and compaction force. It is equipped with heavy-duty 23.1 x 26 tires (8 ply) to ensure durability and traction on various terrain types. The fuel tank capacity is 70 US gallons (265 liters), supporting extended operation without frequent refueling. The compactor’s hydrostatic transmission allows for smooth speed control with selectable working and transportation speeds, enhancing operational flexibility. The roller also includes safety features such as automatic parking brakes and operator-friendly vibration controls with selectable amplitude settings. This model supports high productivity and reliable performance in medium to large-scale civil engineering projects requiring consistent, high-quality surface compaction. It is built with a strong frame and integrated safety systems to ensure operator comfort and machine longevity in demanding construction environments.
