condition (2) on the dashboard. Once
the switch is pressed, the solenoid
valves opens and it will start filling
the air in the bellows to set pressure.
The bellow will expand and will try to
lift the tag axle OFF the ground, but
not completely. This will transfer
some load from the tag axle to the
drive axle. The drive axle will get
sufficient traction to move on the
vehicle. Once the vehicle comes out
of this problem of traction, driver
should press the switch to normal
condition again to bring the tag axle
to its normal position. Bogie lift condition
When the vehicle is in unladen or
partially laden condition (less than
the rated capacity of drive axle),
driver can lift the tag axle completely

bogie lift switch provided on the dash
board. Once the switch is pressed,
the solenoid valves will open and it
will start filling the air in the bellows
up to the set pressure. The bellow
will expand and will lift the tag axle
OFF the ground completely. This will
transfer all load from the tag axle to
the drive axle. It saves unnecessary
wear and tear of the tag axle tyres,
which in turn increases the life of the
tag axle tyres.
NOTE
Driver should not keep running
the vehicle in the bogie press
condition for long time.
