Case DV209CD/Dv210CD Compactors

Case DV209CD and DV210CD rollers combine the compacting forces of a front vibratory drum and rear pneumatic tires.

The DV209CD and DV210CD rollers combine the compacting forces of a front vibratory drum and rear pneumatic tires. With operating weights of 20,753 and 22,440 pounds, respectively, the DV209CD and DV210CD are suitable, says Case, for use on municipal roads, parking lots, and residential developments, as well as larger-scale paving applications, such as highways, airports, and industrial areas. High-frequency drum vibration (up to 4,020 vpm/67 Hz) and dual amplitude settings, says the company, allow appropriate control of compaction performance, based on thickness and density requirements.

Features include automatic vibration control, crab steering, oscillating/articulating roller joint, and pressurized water system. The roller joint oscillates ± 6 degrees to maintain consistent drum-to-ground contact, and the triple-filtration water system is designed to prevent clogs, says Case, and to maintain even flow to all nozzles, even on grades.

A Tier 4-Final, 100-horsepower Deutz engine has a redesigned cooling system, and an automatic idle-control system can reduce fuel consumption by as much as 15 percent compared with previous models.

An optional compaction meter and infrared thermometer monitor material stiffness and temperature in real time, allowing optimum compaction results, says the company. An available printer provides compaction data for verification and record keeping.

The operator environment includes a sliding/rotating seat for good sightlines to the drum and spray bars, tilting/adjustable-height steering column, and adjustable armrests with integrated control switches. A multifunctional display mounted on the steering wheel provides real-time operating data, controls, and diagnostics. Serviceability features include ground-level access to routine service points (fluid ports, drains, service checkpoints, and coolers) via swing-out doors on both sides of the machine.
