ASPHALT MANEGER (BOMAG)
Asphalt Manager (Bomag): Oscillation alignment system which enables stepless adjustment to the direction of compaction force between vertical and horizontal. The maximum possible output is provided, based on a calculation of the rigidity of the material being compacted. Compaction process is calculated continuously and displayed as an EVIB value on a special display, the BOMAG Operational Panel (BOP). The display also informs the operator of the current asphalt temperature, the rolling speed and the currently active amplitude.
Two operating modes:
+ Automatic mode: The roller operator does not need to make any manual settings. Amplitude is automatically adjusted to conditions.
+ Manual mode: The operator can preselect one of six oscillation directions between vertical and horizontal.
ERGONOMIC - EASE OF USE
| Dashboard | |
 | |
| - Dashboard (movable)Classification in colour-coded functional groups - Self-explanatory pictograms that are clearly arranged - International symbols - Backlit | - Fixed display - Operated by rotary knob - The display is located in the middle between the steering wheels, which means that the displays cannot be seen from every seating position - No ergonomic operation of the rotary knob |
| Steering wheel | |
 | |
| - Steering wheel and control panel - movable | - Two steering wheels, adjustable seat |
| Drive lever | |
 | |
| - Drive lever with three positions: Stop (park), forwards and backwards - Button to activate vibration/oscillation, raising and lowering of the edge pressing and cutting equipment - Setting the track offset on the dashboard - 2 drive levers (2nd optional) | - Drive lever with integrated vibration switches, crab steering and raising/lowering of the edge pressing and cutting equipment - 2 Drive lever |
| Comfort | |
 | |
| - Very spacious ROPS-cabin - Boarding from both sides - Large rear storage area (incl. 12 V connector and bottle holder) - Storage for documents and tools - Compact design | - Restricted cabin space due to two steering wheels, among others - Boarding from both sides - Little storage space |
| Seating conditions | |
 | |
| - Seat can be moved seamlessly from left/right - 180° seat rotation - Seating comfort through individually adjustable seat - Steering column adjustment for comfortable seating - Split doors (optional) | - Seat can be moved to the doors - Seat swivel - Instrument panel is fixed; the operator therefore sits either to the right or left beside the instrument panel, fixed grid positions - Steering consoles cannot be adjusted - Steering wheel with tilt adjustment |
| Working environment | |
 | |
| - Excellent overview of drum and working environment - Large panoramic window for optimal view of the front and rear of the drum and of the working environment | - Good view of drum and working environment |
WATER SPRINKLING SYSTEM
| Water tanks | |
 | |
| - Large front and rear water tanks - Each water tank can be filled from both sides - Easy, secure access (on both sides - front and rear) to water tanks - Deep centre of gravity increases driving stability - Simple and quick emptying (three drainage points - right rear water tank + left drain plugs, drain at front water tank) - Water tanks are connected to each other for uniform emptying and weight distribution | - Two rear water tanks (for non-uniform front and rear weight distribution) - Water tanks can be filled on both sides - Dual side access to water tanks - The hose connection on the swivel joint can be opened to empty the tanks - In addition, a second drain is attached in the pump area for faster emptying |
| Sprinkling | |
 | |
| - Sprinkling settings on dashboard - Failure safety due to 2 water pumps (manual switching) - Manual switching from pump 1 to pump 2 (so that both pumps remain functional) - Indicator light for supporting water pump - Optical display of water level - 3-way filtration - 4 sprinkling levels (permanent sprinkling, 3 sprinkling intervals) and manual sprinkling - Speed-dependent water sprinkling | - Operation via rotary knob which is connected to the left of the operator's seat in the driving lever console - Two water pumps (manual switching) - Optical and acoustic warning when water level is low - 12 interval stages - Preset interval stages, not regulated by speed |
| Spray bars | |
 | |
| - Easy installation and removal of spray bars (quick coupling) + nozzles - Clear view of spray bars and nozzles - Sprinkling pipes protected from the wind - Scraper made of plastic - Frost protection and anti-theft protection | - Spray bar is fixed and not easy to empty - Clear view of spray bars and nozzles - Sprinkler pipes protected from the wind - Scraper made of plastic - Radiator in the sphere of influence of the sprinkler, which results in a risk of contamination when dirt is sucked up |
