Smart Doc app from HAMM enables self-monitoring for compactor operators
With Smart Doc, HAMM presents an app with which compaction in earthworks can be transparently documented and the result shared with third parties.
Smart Doc also fulfills the minimum requirements of continuous compaction control (CCC). With an intuitive user interface, the app also creates added value when training new roller operators, as all relevant compaction parameters are visualized in real time on a smartphone.
"We pursue two key aims with the app. Firstly, we offer customers who deal with earthwork sites only occasionally a tool with which they can create proof of compaction very easily. Secondly, we support inexperienced roller operators in their daily work with Smart Doc. They often do not have the practical experience of their colleagues, but are familiar with the digital world. The live display on the smartphone visually demonstrates how compaction develops during the current transit. Consequently, high-quality and homogeneous compaction can also be achieved by young roller operators. So they become more experienced in a fun way," explains Dr Axel Mühlhausen, product manager of digital solutions at HAMM AG.
Available for H series and H CompactLine series
With Smart Doc, every operator of a compactor from the H series or the H CompactLine series can produce a report about compaction. As a prerequisite, the compactors must be equipped with the HAMM Compaction Meter.
As soon as the app connects the mobile phone with the CAN bus of the roller via Bluetooth, the current compaction parameters (speed, frequency, amplitude and compaction value) are transmitted to the app. Consequently, the Bluetooth Low Energy standard ensures an energy-efficient data transfer. Should the battery of the mobile phone be drained, it can be charged via the 12 V socket or the optional USB charging port on the driver's platform.
Economical alternative to complex continuous compaction control systems
The result delivered by the app is a compaction report in PDF format. This shows the essential data on the project and contract section, the technical data of the compactor (weight, drum width and static linear load), the various compaction parameters and the number of transits per compaction lane.The report also contains a graphic that illustrates in which places and how intensively compaction has already taken place.
Smart Doc records data as soon as vibration or oscillation is used during compaction. In order to do so, the load-bearing capacity of the ground is determined by means of an acceleration sensor on the drum during dynamic compaction.
With real-time visualization of the compaction data and the option to generate and show a compaction report at any time, Smart Doc fulfils the basic requirements of a continuous compaction control system. In short - with Smart Doc, HAMM offers an economical alternative for achieving high-quality compaction at earthwork sites with the required basic continuous compaction control in a way that can be verified.
Once the project data has been entered, the recording can be started and stopped automatically when switching on or off the vibration or oscillation. In addition, every transit and every new track can be individually documented and automatically saved.
Once work has finished, the data export is triggered by a tap of the finger. During compaction with vibration or oscillation, the operator can follow the current status live on the smartphone.
The new Volvo EC950F crawler excavator was made for large haulers. In fact, it can fill our 60-ton A60H haul truck in just four bucket passes with an average cycle time of just over a minute. With the perfect pair from Volvo, you can improve efficiency, burn less fuel and keep your haulers moving.
Watch these two powerful machines load four passes in just over a minute.
