The Dynapac CA255 Soil Drum Roller (SDR) is a low maintenance, fuel efficient machine that delivers reliable, high quality compaction to South Africa’s 10 ton market segment.
The CA255 follows close on the heels of its bigger sibling, the CA270 which has done exceptionally well in the 12 ton segment since its introduction in 2012. “Because of the CA270’s success, our emphasis has up to 2016 not been on the opportunities presented by the 10 ton segment,” says Business Line Manager, Dynapac SA, Neville Marthinussen.
“We are certainly focussed on new market development so the much-needed introduction of our CA255 a few months ago has opened up new opportunities for us within the 10 ton segment. Now that we are able to offer a quality Africa spec compaction solution for both the 10 and 12 ton segments, our growth in the SDR segment is evident.
The big contributor is the 10 ton category due to the fact that the CA255 has been very well received. This unit is ideally positioned and priced to fill the gap for small and medium market segments due to its affordability, fuel savings, reduced Rands / m3 compaction cost, higher production ability and consequently low cost of ownership.”
With over 100 years of expertise in compaction knowledge and applications, Dynapac has designed the rugged CA255 for productivity. Featuring a large fuel tank sufficient for a full day’s work as well as front and rear working lights, the machine is capable of working reliably for long hours in tough applications and harsh conditions, compacting most soil types as well as all types of base courses and reinforcement course.
The CA255 is ideally suited for road building as well as layer works compaction required at airfields, ports and harbours, and industrial project sites.
The soil compactor features a 50mm drum frame, is drum driven and heavy duty rear axle with failsafe brakes. The machine’s powerful fuel efficient water-cooled power unit delivers high performance and non-stop operation for maximum reliability at the lowest operating costs.
The advanced feature-rich hydraulic system which includes a closed-loop hydraulic circuit and a lowest in-class hydraulic tank volume further optimises the machine’s efficiency.
The quality of the compaction is determined by two important factors – static linear load and amplitude; the more static linear load, the better the quality of the compaction and the higher the amplitude, the greater the depth effect.
At 30,9kg/cm, the Dynapac CA255 boasts one of the highest static linear loads in the industry compared to similar machines, and offers two different amplitudes – a high amplitude of 1.7mm for thicker layers and a low 0,8mm amplitude for thinner layers.
While frequency is optimised to match amplitude, the CA255 uses electronically operated vibration (vibration pump with EDC) to reduce resonating frequency that can cause structural failure and operator discomfort. Efficient shock absorbers keep vibrations on the operator’s platform to a minimum.
The CA255 is designed to simplify and facilitate maintenance so that downtime is kept to an absolute minimum. The gas strut-mounted FRP hood can be easily opened and lowered to give complete access to the engine, hydraulics and service points.
Dynapac is one of world’s most specialised manufacturers of compaction, milling and paving equipment. The company is renowned for developing ground-breaking cost- effective solutions with high quality, reliable and efficient machines.
Customers have the highest quality machines with low cost of ownership against high productivity and efficiency, low maintenance and fuel cost, and low cost compaction / m2. Dynapac road construction equipment range includes planers, pavers, tandem rollers and pneumatic tyred as well as static rollers.
On 1st July 2017 Dynapac became a company within the Fayat Group, operating under the Dynapac brand name, following the recent sale by the Atlas Copco Group of its global Road Construction Equipment Division which includes the Dynapac brand name.
Family-owned and 100% independent, Fayat is the number one construction Group in France and a world-leader in road construction equipment. “The combined experience of Fayat and Dynapac presents a solid platform to reinforce the strength of the Dynapac brand through continued development, improvement and expansion of product ranges and services as well as training,” notes Marthinussen
He confirms that the Atlas Copco name will gradually be phased out and that the Dynapac brand will be prominently displayed on all products come 2018. “As Dynapac South Africa we will continue to serve the market with our products and services. The current product portfolio remains unchanged and all scheduled product renewals will continue as planned,” concludes Marthinussen
