The ARX 90 StV and ARX 110 StV Articulated Heavy Tandem Rollers are powered by engines that meet EU Stage V and U.S. EPA Tier 4f emissions requirements.

Applications include medium and large jobsites, transport construction (municipal and town roads, motorways, airfields) and building construction (houses and industrial zones).

The rollers all utilise the highly respected Deutz TCD3.6L4 engine. The differences between models results in the after-treatment structure, where there are varied systems for reducing pollution and NOx.  Newly released models are equipped with the most technologically advanced after-treatment system.

• Compaction output

Compaction output is high, and the system is efficient. Each drum has an independent vibratory pump. The rollers also feature a heavy-duty, 2-stage vibrator with a variable range of frequencies.

• Design

The machines are designed to be compact and drive vibration into the targeted materials and away from the operator. The design also provides visibility and comfort that helps make operators productive throughout their shift.

• Steering and traction

The tandem rollers are easy to control, with articulated steering with oscillation and a mechanism that enables work in crab mode up to 17 cm (6,7 in) on both sides. A differential lock is standard.

• Operator friendly

The cab is enormously spacious, comfortable and quiet. Operator-friendly features include a unique multifunctional display in the steering wheel, adjustable steering column, and control switches on the armrest.

• Visibility

A rotating and sliding seat enables visibility with excellent sight lines to drum surfaces, edges and spraying bars. The operator can slide the seat beyond the machine contour for even better visibility.

• Diagnostics and service

Onboard diagnostics quickly alert operators to issues. Service points are easy to access.

• Telematics readiness

Every machine is ready for installation of Ammann ServiceLink for monitoring of machine functions, fuel consumption, required service intervals, etc. Customers also can install telematics solutions from other providers if they prefer.

• ACE^force

The optional ACE^force system is extremely intuitive to operate, with all information in a simple format on the central display. The system offers advanced functions for effortless and safe machine operation and compaction guidance. ACE^force also recognizes if the machine is experiencing a double jump. If so, the system immediately informs the operator of corrective measures to prevent machine damage.

• Oscillation

This motion enables the drums to maintain constant contact throughout compaction. It uses less force but delivers both vertical and horizontal energy – essentially massaging the aggregates into place.

Oscillation excels on sensitive jobsites, such as bridges or when working over sewers or utility lines. In addition, oscillating rollers can safely work on mats that are too hot or too cold for traditional compaction methods. Oscillating compactors also seal joints without damaging cold mats.
