CASE DV207 HF STATIC SMOOTH DRUM ROLLER

Technical Description

The CASE DV207 HF is a high-frequency smooth drum roller designed for efficient asphalt and soil compaction. It features tandem steel drums with a drum width of approximately 57 inches and an operating width of 61 inches, offering robust coverage for compaction tasks. The machine delivers vibration frequencies of 48 and 67 vibrations per minute (vpm), enabling effective compaction density and surface smoothness. It operates at a weight of 16,226 pounds, balancing mass for optimal ground contact and maneuverability. Powered by an 80 horsepower engine with a displacement of 199 cubic inches, the DV207 HF provides reliable performance and hydraulic systems for drum vibration and drive, supporting both single and double drum operation. The operating parameters include a gradeability with vibration of 36%, making it suitable for varied terrain inclines. The roller’s overall dimensions are 173.6 inches in length, 60.6 inches in width, and 116.1 inches in height with ROPS (Roll-Over Protective Structure). Key operational features include a 29-gallon fuel tank and a 158.5-gallon water tank to maintain drum hydration and reduce material adhesion during use. The centrifugal force exerted by each drum is 12,365 pounds-force, distributing substantial compactive effort evenly across the surface. The DV207’s inside turning radius is 181.1 inches, enabling reasonable maneuverability for site conditions. Its robust build and hydraulic system ensure precise control and effective compaction, suited for roadwork, parking lots, and infrastructure projects requiring smooth, dense surfaces.
