Ammann’s new articulated tandem rollers feature a symmetrical cab and fingertip steering
Ammann has developed two new articulated tandem rollers that offer advanced machine control to improve safety and productivity on the jobsite.
The ARX 90-2 and ARX 110-2 articulated tandem rollers utilize the next generation of Human Machine Interface (HMI) that facilitates easy, efficient operation. One component of HMI is fingertip steering (FTS), which makes the rollers more operator friendly, comfortable and easy to control.
Fingertip steering replaces the roller’s traditional steering wheel and allows operators to keep both hands on the armrests for enhanced comfort and control. It also offers palm support that prevents fatigue and injuries from repetitive motions.
“Operators love the fingertip steering,” said Josef Dementev, Global Product Specialist Machines at Ammann. “Their workday is much less stressful, which makes them more productive and makes the jobsite safer, too.”
The operating width of the ARX 90-2 and ARX 110-2 is 1.7 metres. Both rollers are equipped with a two-stage vibratory system with a multiple range of frequencies that help operators precisely adjust compaction output. The ARX 90-2 / ARX110-2 have adjustable frequencies ranging from 37 to 54 Hz and are able deliver compaction output in the range of 47 to 120 kN per drum.
A high frequency (HF) version has an enhanced vibratory system that can reach additional frequencies for further compaction speed.
The machines are equipped with a 121-hp Perkins 904J diesel engine.
Solid Power DNA
The compactors follow the Ammann “Solid Power DNA” motto and are designed to excel in Pro(D)uctivity, Ergo(N)omics, Service(A)bility. These efforts deliver a wide range of benefits such as operating weight, compaction width, a variable range of frequencies, compaction power and off-set mode (crab mode).
The machines are most productive when used in high volume asphalt applications such as highways, industrial developments, parking areas and airfields.
The ARX 90-2 and ARX 110-2 were designed without front and rear crossbeams. This modification improves visibility and safety.
“The lack of beams was key to creating the new symmetrical cab, which is among the key enhancements,” Dementev said.
Design changes also make the machines more compact while expanding sight lines to all drum surfaces and edges.
The symmetrical cab integrates four ROPS posts directly in the main structure and close to doors, rather than in the cab’s corners.
This provides operators with a 360-degree view of the entire machine. The ARX 90-2 and ARX110-2 operator stations extend beyond the 1-by-1 metre rule (in both directions) — another significant safety feature.
The spacious cab is quiet. It’s suspended and isolated from external heat and vibration to keep operators comfortable and focused.
Fuel and water tanks are also positioned to improve the machines’ appearance and access to components.
Intuitive operation
The innovative operator station has integrated, centralized controls that are easy to reach, regardless of the seat position. This approach reduces reaction times for increased safety.
The operator’s seat is fully adjustable, with a 270-degree rotation to optimize visibility.
A new 25-cm control display helps operators manage all machine functions simply, safely and quickly. This includes vibratory parameters, lights and ACE force – Ammann’s proprietary intelligent compaction system.
The display is installed on an adjustable support and moves with the seat for easy viewing.
ECOdrop philosophy
The machines only require a fuel top up once every two shifts thanks to a large 200-litre tank, and reduced fuel consumption that results from a well-balanced hydraulic system and EcoMode’s control of rpm.
The rollers also reflect a commitment to lower the total cost of ownership and machine maintenance. The focus of these efforts is to reduce the volume of fluids required and to make service points extremely accessible. This commitment — known as ECOdrop — makes all new products significantly more environmentally friendly.
As part of ECOdrop, the rollers utilize EcoMode, which enhances fuel economy and lowers fuel consumption by 8 per cent when compared with the previous generation.

Integrated alerts inform the operator when it’s time for machine maintenance. This helps organize scheduling service and parts availability to reduce downtime and lower ownership costs.
An advanced drum drive system reduces gearbox oil usage by 25 per cent when compared with the previous generation of machines. Drum bearing oil bath fluid has been reduced by 7 per cent.
The articulated joint and hydraulic cylinders are completely maintenance-free.
Serviceability
Machine data is collected from all regions and is now reflected in innovative machine development as well as ECOdrop, which makes the machines mostly maintenance-free and more environmentally friendly.
Maintenance is faster and more convenient thanks to a highly accessible engine compartment with a robust design that protects all major components.
All rollers are equipped with an auto-diagnostics system that communicates with service technicians. External testing ports on hydraulic components enable quick diagnosis and reduce machine downtime.
Customization
A wide range of options can make the machines more productive, comfortable and serviceable.
Off-set (crab mode) improves machine versatility by increasing working width and permitting compaction close to curbs.
The machine is also available in a combi version, with four tires to increase usage.
The ARX 90-2 and ARX 110-2 can be equipped with an oscillation drum, which uses the back-and-forth movement of the drum with a constant static load to achieve compaction goals in sensitive applications (such as cold joints, thin layers, etc.). When oscillation is not required, the ARX 90-2 and ARX 110-2 utilize a second drum with a heavy-duty, two-stage vibrator and easy adjustment of amplitude and frequency.
The ACEforce system makes it easier for operators to track compaction progress. This measuring system shows the actual kB value on the display and thus significantly reduces the time required to achieve the maximum compaction level.
