Hamm Compaction division of Wirtgen America Inc. has rolled out two new small articulated asphalt compactors that offer vibration in both the front and rear drums.

The 1.6-ton HD 8 VV, and the 1.73-ton HD 10C VV were first displayed at World of Asphalt 2006 in Orlando, FL. VV stands for “Vibration Front, Vibration Rear.”

The machines have the capability of vibration running in the front drum only, in both drums or no vibration.

These are the first Hamm products in the 30 to 35-in.-wide drum size. The HD 8 VV has a drum width of 31.5 in. (80 cm) and a working width of 33.7 in. (86 cm).

The HD 10C VV has a drum width of 39 in. (100 cm), and a working width of 41.7 in. (106 cm). As they share the same platform, both models have a total length of 83.5 in. (212 cm), and total height of 84.8 in. (215 cm)

Also, both models share a HATZ Model 3W35, 3-cylinder, S.A.E.-rated 21-hp (15.7 kW) engine.

Both models share a cantilevered drum suspension system with a single drum support leg on each side of the machine — right leg only on front, left leg only on rear — that permits compaction right up against an obstruction such as a wall or curb. This design introduces a permanent 2-in. (5 cm) offset to these models.

Both rollers offer hydrostatic dual drum drive, automatic/manual vibration system, hydrostatic articulated steering and maneuverability.

They feature three braking systems with an emergency stop button, a plastic water tank serving a pressurized water system, hand-serviceable, plastic spray nozzles and a fixed 2.2-in. (5.6 cm) offset.
