Hydros tatic Drive S ystem s for Road Rollers
In order to attain sm ooth road s urfaces s ealed
to an op timum level, a repeatable and reliable
precision is required for the s ealing function
carried out by road rollers.
A hydrostatic drive offers the bes t so lution for
this.
Axial piston units from Brueninghau s
Hydromatik are used for transmiss ion and
vibration drives, for additional devices, and in
addition they fulfil the required safety functions.

In addition to the axial piston pump s and motors
with the ass ociated control devices, including
electronics, the Rexroth group of companies is
able to supply al l other components, s uch as
gear pumps and m otors, radial piston mo tors,
valves, control devices, mechanical drives, etc.
The Mannesmann Rexroth group of companies
is ab le to offer a com plete solution for any drive
application. Why not talk to our road roller
sales department?
The quality of the Brueninghau s Hydromatik
products is along with the high level of
technologies the reason for content customers
worldwide.
The certification as to DIN ISO 9001 therefore
is the log ical result of our extensive quality
assurance strategy.

In order to ensu re reliable hydros tatic braking
and in o rder to prevent the motor from
overturning when reversing in un its, driven by
four hydraulic motors, a quadruple flow divider
should be installed for the transmission drive.
