New from Dynapac North America: CO4200 oscillating double drum roller and MF2500CS material feeder product family

FORT MILL, SC — Dynapac North America expands its comprehensive roller product line with the addition of the Dynapac CO4200 Generation VI double drum roller with oscillation. The new roller model delivers an additional heavy compaction solution for operators in a highly balanced and durable machine. The CO4200 VI allows the operator to select the system that is most suitable for the application at hand.

“This new machine was developed based on feedback from end-users of our trusted roller product line, and we’re extremely pleased to launch the new double drum roller with oscillation to the North American marketplace,” said Tim Hoffman, product manager, rollers at Dynapac North America. “Operators will really appreciate the overall durability of this machine coupled with Dynapac’s commitment to providing an extremely balanced roller, ultimately contributing to outstanding compaction results. This new machine is without a doubt designed to perform and built to last.”

According to Hoffman, the latest oscillation technology offered in Dynapac tandem rollers meets specific needs in the marketplace, particularly high-quality compaction in areas where vibration needs to be reduced — like bridge decks or areas adjacent to foundations — or in thin asphalt overlay applications. The oscillation compaction concept can also help reduce the risk of damage for less qualitative aggregates.

The Dynapac CO4200 VI is equipped with heavy-duty and durable components, including a drum shell fabricated from Hardox® 450. This particular grade of Hardox steel provides outstanding dent and abrasion resistance, minimizing wear and tear, and contributing to the overall longevity of the machine.

In addition to the incorporation of harder and more durable steel, the new roller model also streamlines serviceability by providing easy access to belts and other components through the integration of manholes in the drum. Belts can be accessed and replaced in as little as two hours, ultimately reducing downtime and maximizing productivity on the job site.

Like other Dynapac rollers, the new CO4200 VI also features an extremely balanced operating mass for front and rear modules, weighing in at 11,023 pounds (5,000 kg) and 10,802 pounds (4,900 kg), respectively. The balanced design of the new Dynapac roller model helps reduce roller marks and delivers a consistently compacted surface with every pass.

The new models feature an oscillation force of up to 27,450 pounds (122 kN) with an oscillation frequency of 2,400 vpm (40 Hz). When operated in vibration mode, the unit delivers up to 28,780 pounds (128 kN) of centrifugal force and a vibration frequency of 3,060 vpm (51 Hz) in high amplitude mode and 18,880 pounds (84 kN) of centrifugal force and 4,020 vpm (67 Hz) in low amplitude mode. The roller is powered by dual Cummins® QSF3.8 water-cooled turbo diesel engines and can reach ground speeds of up to 7.5 mph (12 km/h).

The new MF2500CS material transfer vehicle (MTV) product family featuring two new models, the MF2500CS and the MF2500CS with SwingApp. These innovative models offer unmatched production capabilities and lowest overall cost of ownership, boasting a capacity of up to 4,000 tons per hour. The units are also extremely versatile and able to handle a variety of material applications, including asphalt, concrete, sand and base material.

“With the addition of these two new models to our comprehensive material feeder lineup, we’re confident we have the most productive feeder solutions on the market today,” said Vijay Palanisamy, product manager, pavers and feeders at Dynapac, North America. “Not only are these machines extremely productive, but they also provide best-in-class ergonomic features and total-cost-of-ownership benefits that will bring a lot of value to Dynapac customers.”

In terms of productivity, the Dynapac MF2500CS MTV features a high performance and durable conveyor belt system that can empty a standard 35-ton truckload in as little as 35 seconds, significantly reducing truck cycle times and boosting overall productivity. With an MTV width of 8 feet, 4 inches (2.55 m), the Dynapac MF2500CS is simple and cost-effective to transport, adhering to standard North American transportation requirements. The models feature a maximum transport mass of 22 tons (20 metric tons).

The MF2500CS is also available with SwingApp functionality, which can transform the unit to an offset feeder by swinging the conveyor belt up to 55 degrees in either direction. This allows for optimal versatility of the MF2500CS, with the capability to handle a variety of feeding applications, including feeding two pavers in a side-by-side configuration, feeding one paver from a different lane or filling medians. SwingApp can be mounted on any Dynapac MF2500CS unit, providing optimum fleet management flexibility. The SwingApp can typically be mounted in less than an hour.

Total cost of ownership is one of the most important benefits of the new MF2500CS. There are a number of contributing factors that help the new product line achieve low total cost of ownership, including well-engineered conveyor belt design, to reduce wear to the components, and simple transportation of the feeder due to its compact transport dimensions. Additionally, averaging less than three gallons per hour of fuel consumption can help reduce operating costs.

There are also a number of ergonomic features integrated into the new MF2500CS. For example, Dynapac’s Clearview platform can raise the operator station three feet with the touch of a button, allowing excellent visibility of the job site. The operator platform on each side of the feeder also allows for swing-out functionality and can pivot 90 degrees for maximum visibility regardless of the specific complexities of the job site. Additionally, the controls of the MF2500 product family are intuitive and simple to use, allowing operators of varying skill levels to effectively operate the machine. The new models are fully automated through the integration of distance control and feeding sensors, and the multifunction joystick integrates main drive and SwingApp functions to put full control at the operator’s fingertips. The large LCD monitor delivers all necessary procedural and diagnostic information along with camera feeds in an easy-to-use interface.

In regards to durability, the new MF2500CS is engineered with heavy-duty components to maximize the longevity of the machine. The belt is fully supported by slat bars and mechanical fastening, and features patented mechanical connections for simple serviceability.

The MF2500CS models are powered primarily by a Cummins® QSB 6.7-C220 diesel engine and can reach operating speeds of over 80 feet (25 m) per minute, and a transport speed of approximately 2.5 mph (4 km/h).
