DESCRIPTION
Brochure RotoTopTRANSCRIPT
Ultra Slim DesignFully Boxed
Effective Work
Saves manual work with
nearly all tasks.
Cost-cutting potential with
the backhoe bucket is ap-
proximately 10 - 50% accord-
ing to usage.
Usually, more than 50% of
operations for which a double
shell type grab was required,
can be carried out with the
backhoe bucket now.
Up to 50% More
Productivity with
the Backhoe Bucket
Rotary joints for all at-
tachment tools.
More than 10 different
rotery joints with up to
7 lines for every type
of usage.
Operating pressure of
400 bar.
Large cross-sections!
For all rotary joints, cur-
rent feedthroughs also
possible.
Patented Technology
The mounting plate is
screwed directly on to the
bearing. This guarantees
long durability.
Models RT 121/201/251/
301 provide the possibility to
install or retrofit a second hy-
draulic motor in order to
achieve more drive torque.
Technological Edge
Ultra slim design for high
breakaway torque.
Extremely shock-resistant
bearing for tough usage on
rock cutters and hydraulic
hammers.
Encapsulated box to protect
hydraulic motors.
Nothing sticks out !
The excavator's digging
forces are not conducted via
the box.
Highly Profitable Investment
All attachment tools can be
rotated limitlessly with one
drive. Therefore it is no
longer necessary to equip
every attachment tool with
its own drive.
By means of rotation in com-
bination with the excavator's
kinematics, nearly all work-
ing positions can be
achieved with every attach-
ment tool in practical usage.
Convincing Features
Low dead weight for high
performance.
Our RotoTop is self-locking.
Advantage: The attachment
tool can't turn away.
Directly mountable to the
boom for high breakaway
torque. Also available as a
sandwich design with a
quick-coupler (on top and
below).
Through Down to the
Last Detail
Fully hydraulic quick-couplers,
such as OilQuick, can also be
mounted in low mounting form.
Well accessible technology !
Grease lubrication makes it
possible to work above and
under the water without
causing an "oil layer".
The RotoTop can of course
be connected to the central
lubricating system.
Modular design: Every part
can be exchanged.
Rotary Quick-Coupler, Directly Mounted for Highest Flexibility
Tough Usage in Tunnel Construction. Worldwide. Strong System Solutions
Our RotoTop is an innovative rotary drive, which is in a leading position amongst excavator rotary drives, not only due
to its weight, torque, rotational speed and low overall height.
The RotoTop turns your quick-coupler into a »rotary quick-coupler« for high performance with the backhoe bucket. It is addi-
tionally possible to limitlessly rotate (360°) any attachment tool on excavators and to thus bring them in any position possible.
Topmost efficiency, reliability and cost effectiveness are convincing arguments for controllers, engine operators and site managers alike.
The RotoTop will put you in a position where you can make the most out of profit-increasing cost-cutting potentials. This will improve your
competitiveness. The RotoTop will pay for itself in no time due to its diverse usability.
The RotoTop has been on the road to success in Germany and abroad for years and proves its performance power on a daily basis.

If several excavators in a company's
machinery are equipped with a fully hy-
draulic quick-coupler as, for example,
the OilQuick, all attachment tools with
and without drive (e.g. clamshells on a
knuckle joint, special pipe grabs with
rotators) can be easily exchanged
amongst the excavators »with Roto-
Top« and those »without RotoTop«.
This innovative development solves
logistic problems on the con-
struction site and provides
highest flexibility.
In case some or all
excavators have a
RotoTop, larger companies
can also purchase fixed
attachment tools which
again helps with the
cost-cutting.
