A signal sensor mounted on thetransmission measures the difference in the speed of the input and output shaftsto the torque converter. The electronic injection system reduces engine poweraccordingly. If the torque converter approaches stall condition, the engine rpmwill be reduced, therefore the engine is always at full useable power for anyapplication.The engine complies with 97/68/EC Stage 2 and with 1996 US EPA and CARBstandards.HYDRAULICSYSTEM721D721DXTVariable output “Load Sensing” type closed centre hydraulic system.A tandem variable output hydraulic pump with axial pistons.Maximum output:206 l/min206 l/minPressure:250 bar250 barDouble acting cylinders Arm (2)(bore x stroke)121 x 828 mm121 x 828 mm Bucket (1)(bore x stroke)146 x 629 mm114 x 857 mmPressurised hydraulic tank integrated into the cooling assembly.10 µ return filters.Cycle timeRaising (full bucket)Lowering (bucket empty)DumpingTotal5.59 sec.3.29 sec.2.40 sec.11.28 sec.5.59 sec.3.29 sec.1.94 sec.10.82 sec.ELECTRICAL SYSTEM Voltage 24 Volts Batteries 2 x 12 VoltsCAB4Colori compositiA spacious and comfortable cab provides the operator witha perfect 360 visibility.
