Dynapac has underscored its commitment to helping customers reduce their environmental impact by developing the unique electric powered CC900e tandem roller.
The new machine is designed to compete in the 1.5 tons tandem vibratory roller class. It features a drum width of up to 1.0 metres, develops a centrifugal force of 16.7 kN, a nominal amplitude of 0.4 mm, and a static linear load (front/rear) of 6.1/7.9 kg/cm.
But, unlike the diesel fuelled model upon which it is based, the new CC900e tandem vibratory roller produces zero emissions at the point of operation.
The new CC900e arrives at a time when many equipment manufacturers are looking to electric power to help reduce and ultimately eliminate exhaust emissions.
Yet this is not a first for Dynapac. In fact, the company produced a battery-powered concept machine as far back as 2010. That machine was ahead of its time. But with electric machines becoming increasingly popular, particularly among equipment rental fleet operators, the time for the CC900e is now perfect. Initially, the CC900e will be produced in limited edition.
Developed in Partnership
Weighing in at 1.6 tons and with an operating width of 0.8 to 1.0 metres, the CC900e double drum vibratory roller has been designed to satisfy the specific demands of utility contractors and rental fleet operators alike. It delivers the same linear load, amplitude, frequency, and travel speed as the diesel-powered model upon which it is based.
To ensure this revolutionary new product met the specific needs of end users, Dynapac developed the electric-powered CC900e in co-operation with one of those customers; global contractor SKANSKA. From the very beginning of the research and development phase, SKANSKA reviewed specifications and prototype machines. Another customer, LOXAM, the N°1 equipment rental company in Europe, also provided valuable feedback.
“Co-operation is the key to developing a successful product and direct user input is incredibly valuable to a project of this kind. From the user perspective, it is equally important to be acquainted with the equipment at an early stage,” said Dynapac’s Fredrik Åkesson.
“Even though the compaction performance is unchanged, there are still small changes to the work procedures when transitioning from traditional fossil fuel to electric power. The earlier operators can be exposed to those changes, the easier it will be to adapt to the new equipment.”
Emission-free Future
The electric-powered CC900e unit was in development for more than two years and involved a 20-person research and development team. Although the battery system used in the new model is both proven and popular, it was subjected to rigorous testing to ensure it met the specific needs of the compaction equipment sector and can withstand the vibration generated by the roller. During that testing, prototype machines clocked a massive number of hours in operation.
“We have seen electric and battery power being applied to mini excavators, skid steer loaders, access equipment and site dumpers. These have been widely welcomed by forward thinking and environmentally aware rental fleet operators and contractors. The only thing missing has been an electric-powered tandem vibratory roller to run alongside these other zero emissions machines.”
“With the development of the CC900e, Dynapac has taken a massive technological step.”
