Hamm offers a wide range of products for all aspects of soil and road compaction, utilizing leading machine and compaction technology. Along with the technical requirements, ergonomic design and simple operation are prime concerns. Focus is on features such as the degree of innovation, functionality, ergonomic design, safety, durability, finish and environmental sustainability. Design thus chiefly focuses on a high serviceability.
HAMM finds a perfect balance of technology and ergonomic design.
The Hamm plant is located in Tirschenreuth, some two hours’ drive from Munich. More than 750 people work here. The products developed here not only display a high functionality and cost-efficiency, but also have an attractive futuristic design typical of Hamm products.
For many years, design and reliability have been an essential element of product development at HAMM. And this is one of the reasons why HAMM is continually able to launch innovative machines and concepts on the market whose user-friendly design ensures top productivity,unbeatable reliability & uptime at a very competitive price.
The oscillation system developed by Hamm is not based on complicated mechanical rule mechanisms, but uses alone in an intelligent way the physical laws. Depending upon material rigidity of the underground thereby the amplitude value adapts automatically. That means the amplitude is reduced continuously according to the rising soil rigidity. As the amplitude reduces accordingly, the performance transferred to the soil rises itself…
An optimum at compaction quality
This innovative technology allows the Hamm oscillation rollers practically immediately – within 10 milliseconds – to adjust to changed soil conditions. This corresponds to a distance covered by the roller of only approx. 1 cm. Through those continuously working static load and the changing dynamic shearing stresses in the material, a faster, better and more careful compaction takes place.
Oscillation on all job sites
On all bitumen job sites – from the smallest surface, brides, multi-storey car parks up to highways – the oscillation shows its performance and clear advantages. The oscillating movement in combination with the permanent static load of the drum guarantee a fast increase of compaction paired with very homogeneous compaction and good surface roughness. The sub base remains thereby preserved.
Compaction on bridges becomes just now possible
Oscillation rollers are particularly demanded for bridges. They allow high compaction performance and produce no damaging vibrations. Just on such buildings the bitumen cools down faster by the sea breeze. That is no problem for the oscillation because with oscillation it is possible to work on even lower bitumen temperatures.
Good compaction on joints
At the joint between two driving lanes, e.g. with the renewal of a lane, the oscillation avoids a damage of the other already finished i.e. compacted and cooled down roadway. Also transverse travels are easily possible – there is no danger at any time for the road surface.
More flexibility with the Asphalt temperature
Compaction works are only possible within a certain temperature range, depending on the kind of the used bitumen. Starting from a certain temperature the vibration cannot be used any more, it then develops tear or other damage. With oscillation the temperature range is widened around nearly 20%, i.e. the oscillation roller can still continue to work and ensures therefore a higher flexibility on the job site.
