Hydraulic chassis system - roll stabilisation with load compensation
ROPA has developed an innovative chassis concept with an oscillating front axle in conjunction with two hydraulically supported rear axles for the flagship Tiger. Compared to the chassis on previous 3-axle beet harvesters (with the central axle fixed to the frame), this reduces the sway of machine by one third! The reason for the improvement is the hydraulic connection of the cylinders at the front and rear axles on one side, so unevenness at one wheel at a different level only affects the frame by 33 per cent compared to the previous system. Thanks to the reduction of the chassis swing, the row and depth control are improved simultaneously, as the frame is averaged to the position of three axles. The hydraulic connection of the axles always distributes the load equally over all 6 wheels.
Less sway, significantly greater driving comfort and better harvest quality.
Soil-protective hydraulic chassis system
ROPA R-Soil Protect is the combination of a soil-protective, hydraulic chassis system with new MICHELIN CerexBib tyre technology. This soil protection concept was awarded a silver medal at Agritechnica in Hanover. It only requires 1.4 bar tyre pressure and it is available as an option in the Tiger 6. The synergy of the load-balancing hydraulic chassis with the new generation of MICHELIN IF1000/55 R32 CerexBib tyres offers even more contact surface with sustained soil protection and significantly reduced contact pressure.
Only 1.4 bar tyre pressure, lower contact pressure even with a full beet bunker.
Increased soil protection with significantly reduced load peaks
Hydraulic chassis system R-Balance
Slope compensation up to 10%
The automatic levelling system using six hydraulic cylinders and sensors is unique among 3-axle beet harvesters. The chassis is kept completely horizontal for up to 10 percent side slope. The gravity centre and, thus, the load of the wheels on the slope bottom side are shifted to the slope top side.
Centre of gravity and soil pressure compensation
The track depth of the wheels on the slope bottom side is substantially reduced, the infiltration capacity is retained, thus significantly reducing erosion risk during heavy rains. The slope stability and traction increase greatly, the risk of tipping over is considerably reduced alongside with increased driving comfort. Soil-protective sugar beet harvesting also on the side slope without additional tyres inflation pressure increase!
Reduced soil pressure
The increased and soil-protective tyres of the new Tiger make him look very imposing. Good soil protection is ensured even with full bunker of about 43 m³ and 30 t by Michelin 800/70 R38 CerexBib2 tyres on the front axle and optional Michelin CerexBib IF1000/55 R 32 CFO tyres on the rear axles. The soil is protected alongside with improved damping characteristics at only 1.4 bar of tyre inflation pressure in all six wheels.
The MICHELIN CerexBib IF1000/55 R 32 is the new generation of tyres for sustainable soil protection.
