Ammann reduces roller ownership cost with gasoline engine

The new Ammann ARX 10.1 StV light tandem roller is gasoline-powered and features side-free drums that allow compaction on the tight jobsites.

The tandem roller utilizes the 21-hp Honda GX630 gasoline engine, which reduces ownership costs. 

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

Beyond size, gasoline is generally less expensive, so there is likely a cost advantage with every filling of the tank. As well, there is no need for a diesel particulate filter (DPF) and the cost and hassle that go with it.

Maintenance of a gasoline engine is less costly than maintenance of a diesel engine, and the fuel is often more convenient for smaller construction companies and rental customers.

Side-free drums

The Ammann ARX10.1 StV is the only machine on the market with unique 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. The drum working widths are 90 cm and are installed in-line.

The hydraulic system is the core of the powertrain structure. Both drums are equipped with 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 16.4 kN at 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 litres. 

An interval water flow regulation mechanism, controlled by the operator, ensures optimal water flow and extends sprinkling time. 

A two-stage filtration system  is easy to reach and can be cleaned without draining the tank.

Easy operation

The operator platform is 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. An easy-to-grip handle and a design that places the steps outside of the machine contour helps boost safety and convenience. 

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

Cost of ownership

The ARX 10.1 StV is designed according to the Ammann ECOdrop philosophy, which utilizes advanced engineering to deliver maintenance-free solutions, minimize fluid usage and maximize access to filters. 

The roller is equipped with a maintenance-free steering cylinder and articulation joint that utilizes a spherical ball bearing, which is lifetime greased and 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.

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