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.
