After engaging ordisengaging shifters, constant pneumatic air pressure is not required in VASGearboxes as a separate ball spring assembly is installed in the shifterassembly to LOCK the shifter shafts after shifting. Pneumatic air pressure isonly required to shift (engage or disengage) the shifter shafts, aftershifting, pneumatic air pressure can be removed.
Both Driveline throughput(vehicle in motion) and PTO Aux. Applications cannot be engaged (operated) atthe same time. Either the vehicle shall run on the road (Driveline) or in astationary position the PTO Auxiliary Outputs can be engaged. This VAS Uniquefeature eliminates the possibility of an auxiliary application accident whilevehicle is in motion. If Both Driveline and PTO Aux. applications are required(to be operated) simultaneously, kindly refer to our Combination Reductionmodels CR4, CR7 & CR8 series gearboxes which have both driveline & PTOAux. simultaneous options with Reduction Driveline feature.
