PLANETARY PORTAL BOGIE AXLE
Product features:
> The PTA axle product range was especially designed
for forestry and oroad applications which require
a very high spread of ratio possibilities
> The axles are designed with a portal housing
for optimised ground clearance
> Additionally equipped with a planetary drive on
the wheel ends, these axles provide deeper ratio
and higher torque than standard bogie axles
> Moreover, all PTA models can be equipped with the
patented “Permanent Bogie Balancing System“ (PBBS®)
> PBBS® increases the tractive eort by counteracting
the boogie lifting eect
