Both Drivelinethroughput (vehicle in motion) and PTO Aux. Applications cannot be engaged(operated) at the same time. Either the vehicle shall run on the road(Driveline) or in a stationary position the PTO Auxiliary Outputs can beengaged. This VAS Unique feature eliminates the possibility of an auxiliaryapplication accident while vehicle is in motion. If Both Driveline and PTO Aux.applications are required (to be operated) simultaneously, kindly refer to our300 & 360 series gearboxes which have both driveline & PTO Aux.simultaneous options.
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.
Superior Performance and Durability
Constructed from cast iron with precision-machined, alloy steel gears, the VAS HT21S offers exceptional durability and strength. Its planetary gearing arrangement ensures compactness and even load distribution, while oil bath lubrication keeps the system running smoothly during continuous operations.
High Efficiency and Low Noise Operation
Operating at an output speed of 70 rpm and delivering 2.2 kW of rated power, the HT21S maintains a remarkable 95% efficiency. Its advanced helical gear design and involute tooth profile minimize vibration and keep noise below 65 dB, making it ideal for noise-sensitive environments.
Versatile Industrial Applications
With a flange mounting configuration, IP55 protection, S1 continuous duty cycle, and reversible direction, the HT21S adapts seamlessly to varied industrial settings. Its reliable performance and robust construction make it a sought-after choice for Indian exporters, manufacturers, and suppliers.
FAQ's of VAS HT21S:
Q: How is the VAS HT21S planetary gearbox installed?
