The Dynapac CA151 is a static smooth drum roller engineered for efficient compaction in road construction and similar applications. It features a 66-inch wide steel drum that operates at vibration frequencies between 1,740 and 1,890 vibrations per minute, providing effective soil and asphalt compaction. The machine’s operating width is 74 inches, allowing for broad coverage in a single pass. It is powered by a Cummins engine, known for its robust performance and reliability, driving the roller at speeds up to 11.2 mph. The unit’s operating mass ranges from 14,550 to 15,880 pounds, ensuring sufficient ground pressure for compaction tasks. The hydraulic system includes a parking brake that engages automatically when the engine stops or hydraulic pressure drops, enhancing operational safety. The inside turning radius is 91 inches, supporting maneuverability on a variety of job sites. The Dynapac CA151 is equipped with 14.9x24 tires, has a maximum theoretical gradeability of 42%, and a fuel tank capacity of 49 gallons, facilitating extended work periods. Its electrical system consists of a 12V, 170Ah battery and a 12V, 95A alternator, supporting reliable startup and auxiliary functions. The machine is designed to balance powerful compaction capabilities with operational control and durability, making it suitable for medium to large-scale paving and compaction projects.
