The HX series, the new flagship in the HAMM fleet for asphalt construction, is designed for high-quality compaction. The HX 70i model (7 t/55.4 kW) and HX 90i (9 t/74.4 kW) achieve high surface outputs on large construction sites, but also impress in the most challenging tasks, such as compaction in curves. The high level of precision is possible thanks to pivot steering with an extremely large turning angle, a very large track offset and four steering modes.
Split drums and automatic reversing
The well-conceived compaction technology with split vibration and oscillation drums actively prevents cracks and bulges from forming in the asphalt. The automatic reversing with electrically adjustable seat operating unit also guarantees quality and comfort. It brakes and accelerates the rollers quickly, but smoothly. The seat also turns automatically in the direction of travel when reversing. This is unique in the market. It produces first-class surfaces and ensures ergonomic operation with top safety.
Smart Compact: The intelligent compaction assistant
On request, HAMM equips the rollers in the HX series with Smart Compact, the new automatic compaction assistant. It actively supports the driver and is easy to operate. Smart Compact may be of great interest to the current generation of drivers and, in particular, to those just starting their careers. This compaction assistant combines the simple operation with handling via smartphones, computers and other digitally controlled devices. It therefore meets the changed personnel requirements at modern workstations in road construction.
The automatic mechanism sets compaction parameters for each drum
The driver then only has to enter whether a base-, binder or asphalt surface course is to be compacted. The Smart Compact takes care of the rest: The assistant decides automatically whether to compact with vibration and big or small amplitude, with oscillation, or statically. To this end, it evaluates physical properties of the asphalt, such as the temperature or rigidity. New features include the integration of local weather data via an integrated weather station and the assessment of the complex cooling behaviour in the area of tension between the asphalt and air temperature, as well as the wind. Based on all of this information, the system determines the right setting separately for both drums. This means that HAMM is the first manufacturer in the world to automate the separate setting of the individual drums and is therefore raising the quality of the compaction to a whole new level.
