While Vögele's Super 2100-3i has a new-generation Cummins engine that offers high efficiency and low emissions, as well as lower noise levels, the company emphasizes that "its 'dash 3' encompasses more than just conversion of the engines to meet statutory requirements." In fact, the 2100-3i is "a completely new product with innovative technical features and a modern design."
With a power output of 186 kW (240 hp) at 2000 rpm, the SUPER 2100-3i paver's six-cylinder Tier 4 Interim diesel engine can handle laydown rates up to 1100 t/h (1200 ton/h). The fuel-saving ECO mode with 175 kW (235 hp) at 1700 rpm is expected to be more than adequate for the majority of paving jobs. Vögele says the suffix "i" in the paver's name stands for "intelligent emission control."
One of the new technical innovations that Vögele emphasizes is the paver's splitter gearbox with the ability to disengage hydraulic pumps. When the paver is stationary, all hydraulic pumps for traction, conveyors and augers, and compaction are automatically switched off after about one minute. Fuel consumption is reduced considerably by this new function. Reducing the trailing load also makes it significantly easier to start the paver at low outside temperatures.
Other new features include an energy-optimized tamper, which is driven by a variable displacement pump that always delivers exactly the amount of oil needed for the current tamper speed and "not a drop more or less."
A variable-speed fan automatically adapts to different parameters, such as temperature of the hydraulic oil and engine load. This reduces noise levels as well as consumption. A bypass circuit allows the hydraulic oil to reach its optimum operating temperature very quickly. This in turn permits rapid, fuel-saving operation of the paver. If the oil temperature rises above the optimum level of 50-70°C (122-158°F), a bypass diverts the oil through the cooler assembly.
The ErgoPlus operator environment has been upgraded for the dash 3 generation, with numerous additional ergonomic and functional advantages, says Vögele. The clear and logical arrangement of controls and the ergonomically designed workplace allow the operator to work safely and productively.
The redesigned four-color display, for example, has a high-contrast user interface ensuring brilliant visibility even in poor lighting conditions. The graphic user interface has self-explanatory symbols that are understood in all languages and allow the operator to work intuitively.
Also, the paver operator’s seat and console on the operator platform, as well as the screed consoles, can now be adjusted even more easily to the operators’ needs. Side panelling affords effective protection from the wind and rain.
With the new AutoSet function, the paver is quickly and safely prepared for a move on the job site. Screed, augers, hydraulic hopper front, and deflectors in front of the crawler tracks are raised to transport position simply by pressing the Execute button.
After the move of the paver on site, all components are reset to their previous working positions and paving parameters are retrieved, simply by pressing the button again. This ensures that no settings are lost when changing between Pave and Job Site modes. It also effectively prevents damage during transport. Each function can be activated and deactivated separately via the ErgoPlus menu.
The PaveDock Assistant is an efficient system that facilitates communication between paver operator and driver of the feed vehicle, considerably improving process reliability during transfer of the mix. The signal lights on the paver and the controls on the paver operator's ErgoPlus console are the key components of this communication system.
The paver comes with two signal lights mounted on the right and left of the hardtop. With these lights, the paver operator can give the driver of the feed lorry unmistakable signals, indicating what needs to be done (e.g., reverse, stop, dump). Having two lights, each in an elevated position, ensures that all signals are clearly visible to the lorry driver from all sides.
Push-rollers are an available option for the new dash 3 paver generation. Jolts from the feed lorry are absorbed very efficiently. As soon as the lorry docks onto the paver, a sensor is tripped and delivers a signal to the PaveDock indicator system. The lorry driver can react instantly, thus ensuring that the mix is transferred safely and without jolts for a top-quality pavement result.
