Vibromax 752C details:

In the fall of 1999 Vibromax introduced the new 752 series C tandem drum vibratory roller. The 752C has a significant increase in engine power to 110 hp (82 kW). The operating weight was increase to 23,300 lbs. (10568 kg) while keeping the same 66 inch (1675mm) drum size.

The new roller uses the Cummins 3.9 liter 4 cylinder turbo charged engine. The new engine is tune to meet the latest EPA emissions standards.

A Mannesman Rexroth variable displacement, axial piston hydrostatic pump, used for machine propulsion, mounts to the flywheel end of the engine. It provides oil to the front and rear drum drive motors in a parallel path. The Rexroth 2 speed drum drive motors are mounted on the left side of the drums, drive through L&S planetary gearboxes, and are isolated from the drum by rubber buffers. This arrangement is use in the heavy roller models with a great deal of success. These machines come standard with parking brakes at both the front drum and the rear drum. A spring applied-hydraulically released multi disc brake is part of the drum drive gearbox.

The vibration system on the 752C uses a Rexroth hydrostatic pump mounted directly behind the propulsion pump. It is similar in design to the propulsion pump. The vibratory pump supplies oil to a Rexroth hydrostatic motor mounted at the right side of the drum. The new model 752C operates at frequencies of 1980 or 2520 vibrations per minute. Vibratory operations can be done with front drum only, both drums together, or rear drum only.
