Vögele America is expanding its product family in North America with the introduction of the Vision Series, its next generation of asphalt pavers. The series—completely new according to Vögele—includes the tracked Vision 5200-2 and the wheeled Vision 5203-2, and it also features a number of Vögele Super Series technologies.
Vision Series pavers are powered by a six-cylinder Cummins engine that provides 240 hp (179 kW) at 2000 rpm. Operator-selectable speed ranges—MIN, ECO Mode, and MAX—can be chosen based on power, fuel consumption, and noise level requirements.
Twin raked exhaust pipes redirect exhaust, heat, and noise away from the operator and crew by reinforcing the impression of forward movement. Coolant, hydraulic oil, and charge air are controlled by a large cooler assembly with innovative air routing and a high cooling capacity.
Machine and hood have been sloped to maximize operator visibility for the sides, hopper, and rear conveyors. Operator stations swing out from both edges of the machine, for superior visibility, and the control console slides from one side of the paver platform to the other. An optional hydraulic front apron reduces shoveling in front of the paver by preventing forward spillage of asphalt mix; as the hopper closes, the front apron rises.
Self-diagnostics built into the new Vision Series allow operators to monitor fluid levels and other inspection points from a display panel. A clamshell hood opens completely to allow interior access to routine maintenance points from the deck and sides. Harnesses are simple, supported by the Vision Series’ CAN bus system.
Three drive versions are available on the wheeled Vision 5203-2: one with rear-wheel drive, one with optional two-wheel front-wheel assist, and a new optional version with six-wheel drive. For the Vision 5200-2, long crawler tracks with large ground contact provide maximum tractive effort. Reducing the clearance between track rollers and the rubber track to zero has allowed Vögele to eliminate misalignment of the rubber track, which results in accurate tracking with no bobbing and weaving. Tracks are driven and controlled independently, providing strong tracking stability and a precise turning radius. A strike-off plow or plate at the very front of the paver is mechanically lowered to prevent the machine from going over a hump of material or getting asphalt mix in the tracks.
Independently operated hopper wings allow the Vision 5200-2 and 5203-2 pavers to dump one side or the other or both at the same time. Flow gates have been replaced by independent, reversible conveyor and auger drives, with each conveyor driven separately and independently from the auger.
Hydraulic cylinders keep the self-tensioning conveyors adjusted, which allows the crew to spend less time on the paver and more time placing asphalt. Heavy, fold-up tool racks are provided, and lockable compartments are available under the deck and each operator.
Driven by individual closed-loop hydraulic drives, conveyors and augers are monitored and proportion-controlled to guarantee a constant head of mix in front of the screed. Hydraulic auger height adjustment helps to optimize the spreading of the mix even when paving thin layers or on sections with varying layer thickness. Large 16-in (410-mm) diameter auger flights with precision pitch provide even spreading of the mix when paving in large widths or lower engine speeds. Conveyors and augers can operate in manual, automatic, or clean mode, which allows the augers and conveyors to run at a slow speed for easier cleaning at the end of a shift.
Three electric screeds will be available for the Vision Series pavers: Carlson EZ-III 1017 and EZ-IV 1019 screeds with front-mounted extensions and the HR 500 E rear-mounted screed. No diesel-heated screeds will be available.
Push-button controlled paver functions are logically arranged and clustered in groups, and large, easy-to-read displays on the operator’s and screed operator’s consoles show critical paving data. The operator’s console lights up automatically as darkness falls.
Vision Series pavers offer Pave Mode, a “smart” memory feature that stores the most recent settings for paver functions for future applications. Hydraulic screed hold and screed freeze functions prevent the screed from sinking after a paver stop, eliminating humps when resuming paving. Vögele’s Niveltronic Plus provides automated grade and slope control.
