Smart Compact: The intelligent compaction assistant
Coinciding with the launch of the new tandem rollers from the HX series, HAMM is also bringing the Smart Compact assistant to market. This system actively supports drivers in selecting the right drum and the right type of compaction (vibration, oscillation or static). When operating the roller, the drivers simply specify whether a base-, binder or asphalt surface course is to be compacted. Smart Compact takes care of the rest. The system does this by evaluating different physical properties of the asphalt, such as the temperature or rigidity. It also takes into account the complex cooling behaviour of the asphalt. There is also the option of integrating a weather station to provide local weather information. Smart Compact uses all of this information to determine the most suitable compaction settings for each of the two drums. This makes HAMM the first manufacturer in the world to automate the separate setting of the individual drums, increase process reliability and raise the quality of the compaction to a whole new level.
Fuel savings included
Equipped with these measured values, Smart Compact recognises when dynamic compaction is no longer advisable – for instance, if the asphalt temperature is too low. The system then automatically cancels the dynamic compaction and puts the roller into ECO mode. This reduces the engine speed by up to 20%. This alone reduces fuel consumption by up to 15%. Because of this, Smart Compact preserves not only the machine but resources too.
From the operator's perspective, one of the best things about the assistant is how easy it is to use. Data input and data output are managed via a dedicated display on the dashboard; and because it turns with the seat, the driver can always view all the relevant information. The user guidance has been developed through a UX design process. As such, it combines the demands of machine operation with the contemporary look and feel, i.e. handling, of smartphones and other digital devices. This allows workers to give their full focus to driving the machine. Furthermore, Smart Compact fulfils the newest requirements of the current generation of drivers and new starters in the road building sector, who demand workstations equipped with cutting-edge technology.
