Finger tip steering makes rolling less tiring

Three steering modes (front, rear and crab), combined with an excellent turning radius and segmented drums, enable Ammann’s new AV 70-2 twin-articulated roller to follow the tightest curves with-out damaging the uppermost surface. Not only does the machine provide leading edge maneuverability, its design allows the drum width to be extended through offsetting. It also features front and rear hydrostatic propulsion. “The AV 70-2 is the successor to our highly popular AV 75 model,” says Peter Price, Ammann Area Sales Manager, Canada. “Not only is this machine excellent for compacting asphalt layers, it is equally effective on mixed surfaces, sand, gravel and stabilizing layers.” A unique operating element of the AV 70-2 is its Finger Tip Steering (FTS) feature. According to Price, “By allowing operators an unrestricted view of the material as well as the drum surfaces and edges, Finger Tip Steering (FTS) allows operators to do continuous and accurate work without tiring.” This results in fewer passes, and “fewer passes means less time on the job, which translates into increased productivity and reduced cost,” added Price.

A rotating seat that slides from side to side makes handling of the roller comfortable and easy. A centrally positioned LCD display informs operators at all times of the selected steering mode and the positions of the front and rear drums. Operating weight is 6,950 kg (15,322 pounds), drum width is 1,450 mm (57 inches), amplitudes are 0.67 and 0.34 mm, and frequencies are 35 and 50 Hertz.
