Out with the old, in with the new, as the saying goes. CASE Construction Equipment’s new E Series takes the place of its previous line of compact vibratory rollers. Targeted toward small and medium-size jobs such as driveways and walking paths, the seven new E Series units come in double drum and combination (front drum/rear pneumatic tire) configurations. CASE says it designed them to work closely around obstacles and to be highly transportable.
The CASE E Series consists of the DV23E, DV26E, DV36E, and DV45E double drum models and the DV23CE, DV26CE, and DV45CE combination rollers. The combination models have a rear differential lock option. Drum widths range from 39 to 54 inches (991 to 1,372 millimeters); operating weights run 4,600 to 10,340 pounds (2,087 to 4,690 kilograms). The rollers’ engines are rated at 33.5 horsepower or 43.9 horsepower for the heavier models.
CASE designed the E Series with a high curb clearance and no overhangs. Three operating modes balance performance and fuel economy for loading, working, and transport operations. The rollers also get a boost in fuel efficiency from their ability to create high centrifugal forces and frequencies at lower RPMs, as well as from the CASE ACE Force intelligent compaction system. Ace Force aims to achieve compaction goals in fewer passes, saving fuel and time. It also generates reports necessary for documentation of the work.
The E Series’ user-selectable drive settings allow for either swift turning ability or a smooth ride during compaction. The operator can also choose dual vibration frequencies according to the requirements of the job, along with automatic or manual vibration activation. The latter protects the surface during stops and starts, while the rollers’ offset tapered drums minimize tearing around curves. A long-lasting, pressurized water system consistently sprays the drums but conserves water when the roller is in neutral.
CASE completely redesigned the E Series’ operator controls, which it says are now more intuitive and ergonomic. Additional functions are now closer at hand with the new electronic travel lever. These include the drive settings, RPMs, parking brake, sprinkler controls, and others. The operator seat slides laterally for easy viewing of the drum edges, and the user platform is isolated from the machine to reduce uncomfortable vibration.
