COVER STORY

drum and rear wheels will maintain contact with the ground through the full 10 degree os- cillation even through a full turn. Combine the new articulation joint with traction control and the 3000 Series machines have gradeability that is unmatched in the industry. A further enhancement on the HAMM 3000 Series, is the Hammtronic technology, devel- oped by HAMM to provide an optimum com- paction operation. Its function is to manage all engine and roller functions. The drive, vibra- tion, oscillation and engine speed are all con- trolled by Hammtronic. The rolling speed and vibration system are adjusted with electronic engine management, maximising operating performance. Information is transmitted to the information display and documents the most current data. Hammtronic automatically mon- itors the front and rear drives preventing spin- ning of the drum or wheels further enhancing gradeability. Power on demand technology greatly reduces fuel consumption by as much as 30 to 50%. Power for the 3000 Series is a Deutz water cooled diesel engine that incorporates an innovative cooling system which allows the engine to run at optimum levels and provides a lower fuel consumption rate than competi- tive models. All models are available in either smooth drum or pad foot configurations. The compact tandem roller market is one of the most competitive market segments world- wide. HAMM has dominated this market in most countries with their HD Compactline which now sits at a model range of 16 units.

This places HAMM at the top of the market segment with the largest model range in the sub 4.5 ton weight category. Of the 16 unit model range, four models are equipped with Oscillation technology having one vibratory drum and one oscillating drum. The balance of the range is equipped with either a single vibratory drum or both vibratory drums. The advantage of Oscillation is that it achieves a rapid increase in compaction because the oscillation drum directs tangential thrusting forces into the material to be compacted while remaining constantly in contact with the ground. The combination of continuously act- ing static load and changing dynamic shear forces in the material brings about a faster, better and more gentle compaction. The design characteristics attributed to the HD Compactline ensure that its features con- tribute to the efficient operation of the equip- ment and the comfort and safety of the driver. The HD Compactline rollers offer the operator unrestricted view of the drum edges and the working environment in front, behind and both sides of the unit. The HD Compactline, by virtue of its compact construction can work nearly everywhere es- pecially with their low profile can be ideally used in areas with low ceiling heights. The optional fold away ROPS makes the unit even smaller for ease of transport. The three-point articulation joint is not restricted to the larger units only, for the HD Compactline range has very much driving comfort in mind, thanks to

the three-point articulation joint and flexible positioning of the driver’s seat. The articulat- ed joint effectively acts as a shock absorber and provides excellent directional stability, good stability in turns and a high degree of stability against overturning. Driver com- fort is further enhanced by the driver seat, steering column, lever and footplate being mechanically isolated from the frame. This significantly reduces the amount of vibration experienced by the driver. All HD Compactline rollers offer extremely high levels of side clearance with drums that can be operated in offset position (50 mm in machine models upwards of 2.5 ton) in crab steering mode. This allows for compac- tion right up to the edge, allowing for perfect compaction even on narrow lanes and along curbs. Controls and instrumentation for the HD Compactline is language-neutral and can be mastered in merely a few minutes. The clear unambiguous markings of the control panel make operation virtually intuitive. Power for the HD Compactline range is by means of Kubota water cooled diesel engines either the 3 cylinder or 4 cylinder depending on the model and the territory where they will be operating. Low noise levels and safe oper- ating has been the hallmark of these engines. The HD Compactline offers a tangible ad- vantage and one particularly valued by the majority of rental companies because they are compact, efficient and particularly easy to operate. b
