Ammann makes a steering breakthrough with new roller

An Ammann roller

The new Ammann ARW 65-S walk-behind roller is significantly easier for operators to control, thanks to an innovation in steering that enables the machine to move forward, backward and laterally.

The new S version of the roller has a pivoting mechanism that enables movement in all directions. The previous version only enabled forward and reverse movements. 

With the S version, the machine can also be moved to the right and left via the control handle.

The effortless lateral movement is a significant advantage. The operator is not required to use body weight to direct the machine, which is often the case with walk-behind rollers. This improvement prevents operator fatigue, eliminates surface irregularities and provides consistency throughout the shift, according to Ammann.

“The lateral control makes operating the machine much easier and much more precise,” said Ralf Brutschin, Strategic Commercial Manager for Light Equipment at Ammann. “The steering results in increased productivity, efficiency and quality.”

Hydraulic drum swivel

A hydraulic drum swivel enables movement when going forward or backward. The drum swivels 15 degrees to the left and right. The operator controls the direction by simply pressing one of the two buttons on the steering unit.

The drawbar is shorter, which makes the machine more compact and this improves handling and makes transportation easier.

 A 2-in-1 machine

The ARW 65-S offers two applications — both soil and asphalt compaction — in one machine. 

The 0.3 mm high amplitude setting makes the walk-behind roller ideal for compacting soil and substructures. 

As well, the operator can switch to a lower amplitude of 0.15 mm that is ideal for compacting asphalt and bitumen.

The ARW 65-S is always ready to work on bituminous surfaces thanks to two scrapers on every drum and a 60-litre water tank with sprinkler system.

The ARW 65-S retains all the features and benefits of the previous ARW 65 version.

Engine options

The walk-behind roller is available with engines from Hatz, Yanmar and Honda, providing 8.6 hp, 8.2 hp and 10.5 hp respectively.

The roller weighs 777 kg to 812 kg depending on the selected engine. An electric starter is standard for all three engines.

Isolated guide handle

The height-adjustable handle is designed to prevent unwanted vibration from reaching the operator.  

The ergonomic guide handle includes the dead man’s handle that immediately puts the machine in the neutral position if the operator releases his or her grip. In reverse mode, the roller’s speed limit is set to 2.5 km per hour as a safety regulation.

The roller offers clearance on both drum sides, allowing compaction work extremely close to curbstones, retaining walls and other obstacles. No extra time-consuming work on edges and in confined areas is required.

To reduced maintenance costs, the roller is built without mechanical fast-wearing parts such as V belts and a clutch. In addition, no special tools are required for daily maintenance work.

Hydraulic drive

The hydraulic drive ensures variable speed adjustment and smooth starting/braking action. The drive system utilizes individual drive motors in each drum. This enables high traction and gradeability.

The sprinkling system prevents asphalt from caking on the drums and is integrated into the machine for convenience and to protect the system.

The water tank is fabricated from anti-corrosive materials and has a large 60-litre capacity. The ARW 65-S walk-behind roller utilizes cooling fins on the hydraulic tank, helping the machine perform in even the hottest conditions.

Applications

Ammann walk-behind rollers have always worked for several applications including earthwork, asphalt, sidewalk and cycle path construction and repair, sports grounds, agricultural road construction and maintenance and forest access roads.

The ARW 65-S is also an excellent fit for rental houses because of its easy control and ability to compact soil and asphalt. In addition, rental houses appreciate the low maintenance needs and the optional operating hour metre.

Data tracking

The ARW 65-S walk-behind roller can be equipped with ServiceLink, a digital data management tool that provides customers with the information they want the most.

ServiceLink enables machine owners to track location, battery status and hours used.

Knowing a machine’s location removes guesswork, particularly if multiple jobsites are being managed simultaneously. 

Location data also makes logistics (pickups and deliveries) more efficient, which can have a major impact on larger fleets and rental houses.

Thanks to new hardware from Ammann, data transfer is automatic and access to the information is only a click away via the website myammann.com or on the jobsite through the Ammann ServiceLink app.

Transferring data requires little bandwidth, which led the ServiceLink development team to use a specialized data transmission technology called narrowband IoT, or NB-IoT.

First, NB-IoT requires little power. It also has a strong penetration signal, meaning it can connect in rural areas and across long distances. Data transmission is also secure.

ServiceLink does not require a subscription when used to track light equipment
