About · Ammann ARX45Overview
The Ammann ARX45 is a tandem vibratory roller in the light-to-mid compactor class, with an operating weight of 4690 kg and an engine output of 44 hp. These figures place it at the upper end of the articulated tandem roller segment, where machines balance site mobility with meaningful compaction performance. The ARX45 is designed to deliver consistent amplitude and frequency across asphalt and granular surfaces, making it a well-defined product within Ammann's road-equipment line.
Typical applicationsWhere this machine is used
Tandem vibratory rollers in this weight and power class are used primarily for asphalt compaction on road resurfacing, parking areas, cycle paths, and municipal street work. The 4690 kg operating weight gives the ARX45 sufficient static linear load for base-course and wearing-course compaction without the footprint penalties of heavier single-drum machines. It is also suited to compacting bound granular sub-bases on smaller infrastructure projects where maneuverability around kerbs and junctions is a practical requirement.
Used-market inspectionWhat to check before buying
When inspecting a used ARX45, prioritize a thorough assessment of both drum surfaces for flat spots, dents, or uneven wear patterns, as drum repair or replacement represents a significant cost in this machine class. Check the articulation joint for play and the condition of its seals, since this is a high-stress point on any articulated tandem roller. Verify that the vibration system engages smoothly on both drums and produces consistent amplitude without abnormal noise or vibration at the operator platform. Inspect the water-sprinkling system, including filters, spray bars, and tank seals, for blockages or corrosion, particularly on machines used in colder climates. Review all available service documentation and confirm that scraper blade condition, belt tension, and hydraulic hose integrity have been maintained. A pre-purchase inspection by an independent technician familiar with Ammann equipment is advisable before commitment.
Current marketPrice position
Within the articulated tandem roller segment, the ARX45 is cross-shopped most directly against the Hamm HD14 and the Bomag BW138. The Hamm HD14 is a well-established benchmark in this class and typically attracts buyers with a preference for the Hamm drum and exciter system; the ARX45 competes on operating weight and Ammann's own compaction measurement integration. The Bomag BW138 occupies a similar power and weight bracket and is valued for its widespread dealer and parts network, which can influence total-cost-of-ownership decisions for fleet operators. Within any given price band for used ARX45 units, the attributes that drive spread are recorded machine hours, overall drum condition including any visible denting or flat-spotting, service history documentation, the presence or absence of a water-sprinkling system in full working order, and whether the machine retains its original configuration or has been modified. Machines with low hours, complete service records, and functional ancillary systems command the stronger positions within their band.
