Case announces Tier 4 Final twin roller vibratory asphalt roller

If a high frequency option is selected, frequencies up to 4,020 vpm (67 Hz) can be achieved, which gives better control of compaction performance based on the thickness and density requirements of each laminate. In addition, these two models also have an optional kit that includes a front vibrating drum and an inflatable rear tire to make the paved road smoother and smoother.

The new DV209D and DV210D twin roller asphalt compactors have proven compaction performance while meeting Tier 4 Final emission standards.

The DV209D and DV210D also have a fully adjustable, intuitive and easy-to-use operating environment with a steering wheel instrument panel and digital display.

With working weights of 21,080 and 22,930 pounds respectively, the DV209D and DV210D are ideal construction equipment for municipal roads, parking lot and residential development projects as well as larger paving projects such as highways, airports and industrial areas.

Work efficiency

The new model is equipped with a 100-hp Deutz engine certified by Tier 4 Final and meets DOT project emission regulations. This highly fuel-efficient engine incorporates innovative EGR, DOC, and SCR post-processing technologies. Together with the updated cooling system and automatic idle control, fuel efficiency is up to 15% higher than previous models.

With the standard high centrifugal force and double-amplitude function, working efficiency can be fully improved when working on rough roadbeds, hot asphalt concrete surfaces or recycled hot asphalt concrete; and automatic vibration control can minimize road surface damage and ensure the road surface Smooth and clean.

Articulated roller joints can oscillate in a range of +/6 degrees to keep the roller in contact with the ground, while the standard crab design can hydraulically offset the rear roller by 6.7 inches to ensure precise construction. The DV209D and DV210D are also equipped with a large tank and pressurized triple filtration water system to prevent clogging and to ensure balanced flow for all nozzles when working on ramps.

The optional compaction meter monitors material density in real time, allowing operators to ensure accurate density without over-compaction. In addition, GPS mapping capabilities make it easy to map compaction densities on large sites. With the optional printer, you can easily submit results for DOT approval or for archiving purposes.

Comfort and vision

The DV209D and DV210D have a spacious, comfortable and intuitive operating environment with adjustable sliding/rotary seats that allow the operator to easily see the drum surface, edges and boom. The operator station is also equipped with a height-adjustable tilted steering column and an adjustable armrest with integrated control switch. The multi-function display installed on the steering wheel provides the operator with real-time working data, precise control devices and diagnostic functions.

Easy to maintain

Like all Case Instruments, the DV209D and DV210D are specifically designed to easily perform maintenance tasks on the ground. Large openings are provided on both sides of the machinery and equipment. Operators can easily access all liquid interfaces, drains, maintenance checkpoints, and coolers on the ground for easier maintenance. (This article comes from Case)
