The P6820D replaces the earlier C series machine, with power from the latest generation Volvo D6 engine rated at 140KW, and which meets the Stage IV/Tier 4 Final emissions requirements. A Tier 3 variant is also now available for markets with lower emissions requirements. Weighing in at 14.35tonnes, the P6820D can carry 13.5tonnes of material in its hopper.
The BB78 screed offers paving widths from 2.5-5m, although the machine can be fitted with extensions to allow a maximum paving width of up to 10m. Maximum theoretical productivity is 700tonnes/hour, while maximum paving depth is 300mm. Both single and double tamper bar variants are available, depending on the customer’s requirements.
Meanwhile, the P7820D is powered by a Volvo D8 diesel, delivering 175kW. Both Tier 4 Final/Stage IV and Tier 3 variants are available, depending on the emissions requirements of the local market. The P7820D paver is able to produce 900tonnes/hour of material and with bolt-on extensions, offers a maximum screed width of 11m. Again, this machine can pave to depth of 300mm and is offered with a choice of single and double tamper bar screeds.
Both the P6820D and P7820D are said to be able to function in areas with high ambient temperatures, due to adaptive fan cooling systems. High visibility is claimed from the operator station for both models, with a good view of the hopper and screed areas. Optional LED lighting can be fitted for use in low light conditions and night-time working.
A key feature is the PaveAssist package. CEO Melker Jernberg said, “Data is sent to the cloud to be analysed later.”
The machine is fitted with two thermal cameras to scan the mat. Jernberg said, “It not only takes a thermal picture of the working area, but automatically creates a report that’s uploaded to the cloud.”
The Pave Assist system is designed with an open architecture according to Volvo CE, which makes it more compatible with software from other suppliers. Paver specialist within Volvo CE Martyn Luby explained, “We can live without a GPS system and it continuously stores data in a tablet.”
He said that if the connection is lost the information is stored, and added, “It’ll then download to the cloud when it reconnects.”
The P6820D and P7820D also retain the proven fumes extraction system from earlier Volvo CE machines.
Volvo CE upgrades key asphalt paver models
Volvo CE is upgrading its key asphalt paver models with the addition of its latest generation technology. The company is now fitting the sophisticated EPMIII electronic pavement management system to its new generation P6820D. This machine is also equipped with the new PaveAssist package, which allows real-time monitoring of machine parameters. The P6820D replaces the earlier C series machine, with power from the latest generation Volvo D6 engine rated at 140KW, and which meets the Stage IV/Tier 4 Final em
