CASE introduces Tier 4 Final large-frame combination vibratory rollers
By CASE Construction Equipment
May 29, 2017 - CASE Construction Equipment introduces two new combination vibratory rollers—the DV209CD and DV210CD. The new vibratory rollers compact with the front drum and deliver a smooth finish with rear pneumatic tires. The DV209CD and DV210CD come standard with automatic vibration control, crab steering, an oscillating articulated roller joint and a pressurized triple-filtration water system. High-frequency is offered as a standard feature allowing for frequencies up to 4,020 vpm (67 Hz) for greater control of compaction performance based on the thickness and density requirements of each lift.

The DV209CD and DV210CD also feature a fully adjustable and intuitive operator environment with a steering wheel instrument cluster and digital display.
With operating weights of 20,753 and 22,440 pounds, respectively, the DV209CD and DV210CD are ideal for municipal roads, parking lots and residential developments, as well as more large-scale paving applications such as highways, airports and industrial areas.
The new models feature a Tier 4 Final certified 100 HP Deutz engine that meets emissions regulations for DOT projects. Equipped with an innovative combination of EGR, DOC and SCR after-treatment technologies, the fuel-efficient engine works in combination with an updated cooling system and automatic idle-control to reduce fuel consumption by up to 15 percent compared to previous models.
Standard high centrifugal forces and dual amplitudes maximize productivity on coarse bases, hot-mix asphalt surfaces or recycled hot-mix asphalt, while the automatic vibration control minimizes surface damage and delivers a smooth finish.
An articulated roller joint oscillates + /- 6 degrees to maintain reliable drum-to-ground contact. The DV209CD and DV210CD also feature a large water tank and pressurized, triple-filtration water system that prevents clogs and maintains even flow to all nozzles – even while operating on grade.
An optional compaction meter and infrared thermometer monitor material stiffness and temperature in real time so the operator can achieve precise results without over-compacting. With the available printer, results can be easily submitted for DOT approval and kept for record keeping.
Comfort & Visibility
The DV209CD and DV210CD feature a spacious, comfortable and intuitive operator environment with an adjustable sliding/rotating seat that provides excellent visibility of the drum surfaces, edges and spray bars. The operator station also features a tilting and adjustable-height steering column and adjustable armrests with integrated control switches. A multifunctional display mounted on the steering wheel provides the operator real-time operation data, precision controls and diagnostics.
Like all CASE machines, the DV209CD and DV210CD are designed for groundline serviceability. Large swing-out doors on both sides of the machine provide easy access at ground level to all fluid ports, drains, service checkpoints and coolers for simplified maintenance.
