Multiple applications for walk-behind roller

A safety system limits the speed of the ARW walk behind rollers when operating in reverse

Ammann says that its walk-behind rollers can be used for two applications. The operator can choose a high-amplitude setting for work on gravel or soil as well as a low-amplitude setting for asphalt and bituminous materials. The units are also fitted as standard with a water sprinkler system and a large water tank.

The ARW rollers offer clearance on both drum sides, allowing compaction work extremely close to kerbs, retaining walls and other obstacles. The hydrostatic-driven rollers are built without mechanical fast-wearing parts such as V belts and a clutch, helping reduce maintenance needs.

The ergonomic guide handle includes the dead man’s handle that immediately shuts off the machine if the operator releases his or her grip. In reverse mode, speed is limited to 2.5km/hour for safety. The hydraulic drive ensures variable speed adjustment and smooth starting/braking action.
