Engines Require No After-Treatment

Petrol Fuel Reduces Ownership Costs of New Ammann Roller

LANGENTHAL, Switzerland – Ammann’s new light tandem roller is petrol-powered and features side-free drums that enable compaction in the tightest jobsites.

The Ammann ARX 10.1 StV utilises the Honda GX630 (15,5 kW / 21HP) petrol engine, which reduces ownership costs on a daily basis. It meets the latest EU Stage V/U.S. EPA Phase III emission regulations.

The engine is more compact than its diesel counterpart. The smaller size enables positioning that allows cooling from all sides, helping the machine to perform in hot ambient temperatures.

Beyond size, the use of petrol brings several other advantages:

Petrol is generally less expensive, so there is likely a cost advantage with every filling of the tank.

There is no need for a diesel particulate filter (DPF) and the cost and hassle that go with it.

Maintenance of a petrol engine is less costly than maintenance of a diesel engine.

Petrol is often more convenient for smaller construction companies and rental customers.

This all-new compactor is the first in a line of Ammann Light Tandem Rollers with petrol engines that meet EU Stage V and U.S. EPA Phase III emissions standards.

Side-free drums

The Ammann ARX10.1 StV is the only machine on the market with uniquely designed drum consoles installed from a single side. This innovation is known as “side-free drums.”

The drums are support-free on the operator’s right side. This allows compaction work on the tightest of jobsites. Drum working widths are 900mm (35,4 in) and drums are installed in-line.

Additional key features

A powerful hydraulic system is the core of the powertrain structure. Both drums are equipped with robust drive motors that bring exceptional traction, gradeability and speed. The motors are equipped with a negative parking brake mechanism that ensures secure parking when the engine is switched off.

The front drum is equipped with a vibratory system capable of delivering 16,4kN @ 76 Hz of compaction power, which is sufficient for a wide range of jobsites. The rear drum is static and has no vibratory unit.

The pressurized water sprinkling system has a tank capacity of 110 liters (29,1 gal). An interval water flow regulation mechanism, controlled by the operator, ensures optimal water flow and extends sprinkling time. A two-stage filtration system (water inlet and central filter) is easy to reach and can be cleaned without draining the tank.

Easy to control

The operator platform is fully isolated from vibration and equipped with a comfortable seat. All operational elements are conveniently located on the main dashboard and can be easily reached.

A multi-functional dashboard display monitors key operating functions. The ARX 10.1 StV is available with a mechanical drive lever that is directly connected to the hydraulic drive pump. This solution brings simple and safe machine drive control.

Steps are conveniently located on both sides of the rear frame to provide easy access to the operation station. Further convenience and safety are delivered through an easy-to-grip handle and a design that places the steps outside of the machine contour.

The narrow design and the longitudinal engine location provide perfect visibility from the operator station to all directions and edges. This significantly improves compaction properties and safety on jobsites.

Cost of ownership

The ARX 10.1 StV is designed according to the ECOdrop philosophy, which utilizes advanced engineering to deliver maintenance-free solutions, minimize fluid usage and maximize access to filters. In addition, a solid design extends life.

The roller is equipped with a maintenance-free steering cylinder and articulation joint that utilizes a spherical ball bearing, which is lifetime greased and highly protected. The vibratory mechanism is lubricated by grease that also lasts for the life of the product, thereby requiring no maintenance and reducing the risk of damage.

The engine location and a wide-opening hood make daily maintenance points and filters easy to reach. The location of fluid drainage points speeds periodic maintenance.

Many applications

The compactor is essential for use on small repair works in city centres, malls and business areas, cycle paths and other applications.

Intuitive control and easy-to-explain operation benefit less experienced operators and those who rent the machine.

Other Ammann Tandem Rollers

The portfolio of Ammann Light Articulated Tandem Rollers consists of machines with working widths ranging from 820mm (32,3 in) up to 1380mm (54,3 in). Operating weights are between approximately 1200kg (2645 lb) and 4650kg (10251 lb).

The compactors are primarily powered by combustion diesel engines in varied emission stages. Ammann has also introduced the first zero emission light articulated tandem roller. It is part of the eMission initiative, which reduces levels of CO₂ and other impurities.
