Dynapac’s CA305 single drum vibratory soil compactor is used in various applications - be it roads, bridges, railways, dams etc. Produced in a state-of-the-art manufacturing facility in Pune, the machine has a compact design with a high front module mass that improves productivity, fuel efficiency, rear visibility, manoeuvrability, transportation, and, hence, the overall performance for compaction on jobsites of all sizes. Available options include a smooth drum and padfoot shell kit for varied soil applications.
With best-in-class static linear loads, Dynapac’s patented efficient eccentric system and the easiest to service rollers in the industry, CA305 is built for industry-leading performance in the most demanding compaction applications. The starting torque of eccentric mechanism during vibration starting or switching from low to high amplitude, saves 50% torque. It saves energy and fuel, which reduces impact of machine operation on the environment. This translates into high performance at lower operating cost.
CA305 comes with better ergonomics and operator comfort like a FNR handle that reduces steering effort by 35%. A spacious platform with a new stylish and sleek hood design gives rear visibility within 1m x1m. The platform is mounted on a shock mount system – an innovative arrangement that reduces jerks. The machine also features a foldable canopy for ease of transportation. A larger hood angle of 65 degrees allows better access to maintenance points for easy trouble shooting and diagnosis.
The Dynapac Bouncing Control enables higher productivity and better surface quality with lower operating and owing costs. This is integrated with the compaction meter that measures the dynamic stiffness of the ground. It warns the operator when the machine does double-jump (bouncing) and ensures better surface finish. The advanced hydraulic components fitted in the machines and tyres give better traction to the machines when working at higher gradients.
A separate view in the machine display indicates the stiffness of the surface as CMV (compaction meter value). The CMV is influenced by the rolling speed, rolling direction (forward or reverse), amplitude setting, and vibration frequency.
