Optimised process: Reducing costs by around 50%.
On most comparable construction sites, the construction process consists of the following steps: Removal and loading, transport, feeding the crushers, crushing, loading, transport, spreading and compacting. With the VC compactor, this process is shortened. The steps remaining are removal and loading, transport to the construction site, spreading with bulldozers, breaking up and compacting with the VC compactor. This allows projects to be completed at a considerably lower cost. In Bad Fredeburg, there was about a 50% reduction in the costs for breaking up and compacting. This is because considerably fewer machines were needed. Straßen- und Tiefbau GmbH only required two VC compactors and a caterpillar vehicle. The two crushers, two baggers and two dumpers originally planned for crushing the slate were not required. Personnel and operating costs were also reduced accordingly. Another benefit was that, by using the VC compactors, the CO2 footprint also significantly decreased across the entire construction site.
Ready for maximum loads with heavy-duty equipment
When crushing rock, the machine components are being used more intensively than during the usual compaction. That is why HAMM has designed the VC machines as heavy-duty equipment. This means that, amongst others, the three-point articulation, underbody, front frame and drum suspension, including the drive, have been reinforced compared to normal compactors. In addition, all VC compactors are set on highly robust earth-moving tyres and operators benefit from a seat with an extra-high backrest. The VC compactor is also equipped as standard with the Hammtronic machine control system and the HAMM Compaction Meter.
Positive feedback on the H 25i VC
Marvin Gallus and Mohamed Khalil were at the wheel of the two H 25i VC compactors in Bad Fredeburg. They were given detailed instruction on how to use the crusher-rollers by a service technician. "We found everything very clear and simple after this. The roller is easy to use," says Marvin Gallus. Both singled out its ease of operation and comfort for praise – specifically the quality of the seat and the amount of space available in the cab. The many details designed to make work more pleasant were also much appreciated. An example is the inclusion of 12-V sockets. "I used one of the two 12-V sockets for a mobile phone. It is really practical," says Mohamed Khalil. In summary, Michael Tillmann, Straßen- und Tiefbau GmbH's construction manager, says: "By combining the process steps, we were able to handle approximately 4500 m³ per day. This is almost twice as much as set out in the original planning schedule."
