Dynapac is now producing two new soil compactor models — the CA 134 and CA 144. These self-propelled soil compactors replace the CA 121 and CA 141 models, respectively.

The compact design of the new soil compactors will ensure compaction in tight spaces, such as trench work, road shoulders and construction sites close to existing structures. The compactors’ versatility and ease of operation will complement plant hire fleets and general construction contractors as well as the rental market, according to the manufacturer.

Ease of operation is a prime factor in the design, as little time is needed to become familiar with the controls, further boosting its appeal to renters. The size also allows ease of transportation via trailers.

The CA 134 has a drum width of 54 in. (137 cm) and the CA 144’s drum width is 66 in. (168 cm). Both drum diameters are 39 in. (99 cm). An overall width of less than 6 ft. (1.8 m) and length of 13 ft. (4 m) ensure that it is easily transportable from site to site.

The operator’s platform is isolated from vibration to create optimum working conditions. All the key data, including specified soil densities, fuel level and warning lights, can be seen at a glance on the highly visible instrument panel, which is fitted as standard.

The Dynapac CA 134/144 compact size coupled with its sturdy design ensures effective performance when faced with the daily tasks and demands at virtually any construction site, according to the manufacturer.

Higher amplitude, vibration frequency and centrifugal force (20,000 lbs.) all contribute to consistent compaction performance. Normal operating amplitude for each model is .067 in. (.17 cm) with a vibration frequency of 2100 vpm.

Special job site applications may be achieved through a choice of operating “option” configurations. Each model has a choice of drum drives, a bolt-on pad shell option for compaction of cohesive soils, and an optional leveling blade.

Robust operation and straight forward maintenance are ensured by long service intervals and small number of service points. Many parts, such as the steering hitch and steering cylinder, are maintenance-free and all service points are easily accessible.

Each model features a water-cooled five-cylinder 84 hp (62.6 kW) John Deere engine which achieves the combination of high torque and low emissions. Its 31 gal. (117 L) capacity fuel tank allows long periods of uninterrupted work, further maximizing its productivity.
