Case DV209D, DV210D Vibratory Rollers With Automatic Vibration Control

March 1, 2017

Case DV209D and DV210D double drum vibratory asphalt rollers feature automatic vibration control, crab steering, an oscillating articulated roller joint, and a pressurized triple-filtration water system.

An available high-frequency option allows 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. A combination option is also available for both models, featuring a vibratory front roller and rear pneumatic tires.

The units also feature a fully adjustable and intuitive operator environment with a steering wheel instrument cluster and digital display.

With operating weights of 21,080 and 22,930 pounds, respectively, the DV209D and DV210D are designed for municipal roads, parking lots and residential developments, as well as more large-scale paving applications such as highways, airports, and industrial areas.

The models have a Tier 4-Final 100-horsepower Deutz engine that meets emissions regulations for DOT projects through a combination of EGR, DOC, and SCR aftertreatment technologies. Case says the 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, according to the company.

An articulated roller joint oscillates + /- 6 degrees, and a standard crab steer design hydraulically offsets the rear drum up to 6.7 inches for precision work. The DV209D and DV210D also feature a large water tank and pressurized, triple-filtration water system that prevents clogs and maintains even flow to all nozzles while operating on grade.
