HAMM 3520 - Mastering every slope
Ingenious power train concept provides a climbing ability in excess of 60%
Hamm compactors 3520 are true classics for earth work because they combine modern design with proven engineering. They put their capabilities to the test day in, day out, in every corner of the world. One of their outstanding features is their climbing ability. Depending on the model and configuration, they can scale inclines of 60% or more, compacting extremely efficiently as they go.
- On the models equipped with Hammtronic, the anti-slip control and continuously variable hydraulic motors ensure optimum traction force at all times.
- On the compactors equipped with Hammtronic, the load-dependent speed control protects the engine and reduces fuel consumption.
- The rear axle with self-locking differential prevents wheelspin.
- The 3-point articulation ensures uniform weight distribution between the front and rear sections and thus outstanding traction even in rough terrain.
Hamm compactor 3520 offers ergonomically optimised workspaces as standard. They allow roller drivers to work with total concentration for many hours at a stretch.
Ergonomically optimised and comfortable
Soil compactor 3520 offers operators plenty of space because every model has a large cabin or operator’s platform, accessible from either side. Another practical and comfortable feature is the spring-mounted, height-adjustable driver’s seat. It can be turned, moved to either side, and also moved forwards and backwards on most models. The rake of the steering column with the dashboard is also continuously adjustable to match. Here, every driver is sure to find his ideal working position.
In addition, there is superb all-round visibility because the cabin and doors are fully glazed. This gives the driver a clear view of the drum at all times. The tyres and the space behind the roller are also fully visible because the engine hood has a slimline, sloping shape and the exhaust pipe is positioned so as not to interfere with the all-round view.
- The cabin can be supplied with or without air conditioning.
- Unobstructed view of the drum
- Continuously adjustable steering column.
- Comfortable driver’s seat, individually adjustable for height and weight.
Operation? It couldn’t be easier!
Display of the HMV value on the dashboard
Clear cockpit overview
In terms of operation, drivers of Hamm compactors 3520 have it really easy: everything is clearly laid-out and self-explanatory. Drive control is via one or two drive levers, depending on the model. The activation switch for the vibration is also located on the drive lever, so that the two most frequently used functions can be controlled with one hand.
The dashboard is notable for its unambiguous, internationally understandable marking and labelling. Here, HAMM has dispensed with language, using clear symbols instead. As a result, these compactors can be operated entirely without language skills and yet always with comprehensive information on the current operating status of the machine – an important prerequisite for highquality ground compaction.
Durable engine technology - For a long machine life
HAMM has also provided for efficient maintenance of the rollers because all maintenance points are located on the same side of the machine.
Efficient and economical
Robust 6-cylinder Deutz diesel engines in Hamm compactors 3520 provide ample power with which to drive all components. At the same time, they have adequate reserves for efficient compaction, even under extreme conditions. They comply with the EU Stage II / EPA Tier 2 or EU Stage IIIA / EPA Tier 3 requirements – that means low exhaust emissions and low fuel consumption.
Intelligent airflow enables the rollers to be operated even in high ambient temperatures. A supplementary fuel filter can also be installed. It eliminates excess water from the diesel fuel, ensuring reliable operation
Quickly done: daily maintenance
The few maintenance tasks on Hamm compactors 3520 are quickly done because the wellilluminated engine compartment is very low, making it readily accessible for the workshop technicians. The engine hood provides another benefit: thanks to the cleverly selected position of the pivot point, it can be opened wide, even in restricted headroom situations. Moreover, all maintenance points and the battery are easily accessible on one side of the machine.
Solutions for value retention
HAMM offers various modules for intelligent maintenance. The most important solutions:
WIDIAG enables WIRTGEN GROUP service technicians to read out the roller’s data log on the construction site. In the event of a fault, this speeds up the diagnosis because WIDIAG supplies valuable pointers to the source of the trouble.
WIDOS covers the complete spare parts catalogue, all instructions, hydraulic, electrical and hose system plans, machine data and documentation, safety instructions, component pictures and service documentation in numerous languages on paper or CD.
WITOS is the WIRTGEN GROUP’s intelligent telematics system for efficient fleet and service management. A SIM card allows the machine data to be transmitted automatically to the WIRTGEN GROUP service professionals. They determine the optimum time for the necessary maintenance work and deal with the upcoming tasks. In this way, the residual value, availability and performance of the HAMM rollers will be kept at a high level for a long time.
Flexible earth work professionals - Universally employable in earth work
With well over 30 different models, Hamm 3520 covers the entire spectrum of medium and heavyweight compactors. It also includes various smooth and padfoot drums as well as different compaction systems. This makes the Series 3000 compactors universally employable – for example in roadbed compaction, earth work or building construction, building embankments and slopes and for compaction during cold recycling or soil stabilisation.
- Available with vibrating or VIO drum (operates with vibration or oscillation), depending on the model.
3-point articulation is different to conventional joints due to its geometric arrangement and connection of the three individual joints and one additional connecting link between the two conventional upper joints. This allows optimum steering, excellent driving safety and maximum driving comfort.
The HCQ modules create transparency, increase compaction quality and make for a high level of efficiency.
HCQ: smart system for maximum compaction quality
High-quality compaction means compacting the ground to the required load-bearing capacity – over the entire area and to the required depth. HAMM has developed various measurement systems to check the compaction and bundled them under the name HCQ. These products aid the measurement, documentation and analysis of the compaction processes and offer the maximum possible flexibility, because they are modular in design and perfectly matched to one another.
HAMM Compaction Meter: measuring subsoil rigidity in real time
The HAMM Compaction Meter (HCM) serves to measure and display the subsoil rigidity. To do so, an acceleration sensor on the drum measures the ground rigidity during dynamic compaction. The measurement result, the HMV value, shows the driver whether or not the subsoil is sufficiently compacted. In many cases, this information helps to reduce the number of passes and avoid over-compaction.
HCQ Navigator: area-wide, homogenous compaction
The HCQ Navigator is a satellite-based documentation system for the collection and display of all important parameters during compaction. It creates a real-time compaction map via the HCQ satellite receiver. It shows the areas that have already been adequately compacted and those that require further compaction on a panel PC in the roller. The data from a number of rollers may also be linked via a WLAN. This enables the roller drivers to compact even more efficiently.
The HCQ Navigator’s mobile panel PC for the display and storage of all measurement data.
HAMMTRONIC (3518 HT, HT P, HT VIO)
The Hammtronic electronic machine management system supports the operator in order to achieve optimum compaction without compromising on safety, cost-efficiency and fuel savings.
