Conveying with ease
Heavy-duty support system
Rolling replaces sliding friction
Energy-efficient rolling principle
Heavy loads are hard to shift. But every rule has an exception. One example is denirug which allows pallets
or crates to be pushed over the rollers with just one
hand. In driven versions, the motor no longer has to
perform at maximum capacity. As a result, energy consumption decreases considerably.
To convey large-sized unit goods, even in straight sections extremely powerful drives are required. Resistance from sliding friction needs to be overcome which
in turn puts substantial strain on the traction and sup-
port elements. denirug heavy-duty support system
­replaces sliding by rolling friction, reducing wear and
tear as well as energy consumption.
Several rotating rollers with no pin transfer the load to
the support, which they roll off, moving the unloaded
rollers over the cage. The very strong rollers and their
small distance to one another make the system very
robust.
Uncomplicated
denirug is modular, so that a roller rug of any length or
width can be produced. The 300 mm or 500 mm roller
bearings are ready to fit. As basic elements, they are
simply placed behind and/or beside one another on a
level base and fixed in the required position. They are
easy to integrate into existing conveyors.
Ready-to-use modules
The ready-to-use denirug modules with their integrated basic components are practical to combine in vir­
tually any way. They come in 800 mm and 1200 mm
lengths, both with and without side guidance plates.
As a result, closed surfaces can be achieved that can
be walked on.
The denirug heavy-duty support system
• cuts kinetic friction
• therefore reducing energy consumption
by up to 90%
• minimises wear and tear
• decreases the number of drives and transfer
points
• enables reliable operation of the conveyor
and makes maintenance unnecessary
• allows faster conveying speeds
• keeps the inclination angle in heavy-duty
conveyors very low
• is low in height
• can be combined to make conveyor rugs
of virtually any size
• is ideal for enhancing conventional
heavy-duty conveyors
• makes efficient processes possible
• keeps investment costs low

Heavy-duty support system
Rolling principle saves energy
Fully tested
The results of a trial at the Technical University of
Chemnitz in Germany are irrefutable. denirug reduces
the friction coefficient μ by around 90%. Numerous
long-term trials have also indicated that, depending
on the application, up to 90% of the energy required for power transmission can be saved and the
wear and tear on the traction element reduced accordingly.
The denirug principle
Similarly to linear guidance systems, denirug
heavy-duty support systems operate with axlefree continuous rollers. Because the rollers are
very strong and the pitch between them small,
the extremely smooth-running system can withstand very heavy loads.
Additional components
denirug conveyors are easy to fit with additional components, making handling pallets, trays, skids and containers simpler.
Feed ramp
The ramp allows accurate in-feed of products along
the conveyor. The varnished, sheet-steel feed ramp can
be placed on the right and left and is screwed onto the
base.
Stopper plate and discharger
This components are optionally available for purchase and are connected with the feed ramp. The purpose of the stopper plate is to provide a stop and the
discharger arranges the goods in the best possible
way.

An experimental setup at TU Chemnitz produced clear
results: Using a denirug heavy-duty support system
reduces the friction coefficient μ by around 90 %.
Rocker
Thanks to new and innovative technology, denirug
­modules are quick and easy to adjust and affix and
drilled to the floor.
Efficient processes
denirug provides full and direct support of heavy loads.
Slider beds and runners that otherwise have to bear
modular belt and standard belt conveyors are therefore
not required. Consequently, new, more efficient processes for heavy-duty applications are feasible. denirug
can replace stacker trucks and therefore eliminate
problems and hazards.

Basic denirug elements
Basic denirug elements are roller bearings ready to fit
that users can combine to make rolling supports in virtually any length and width. denirug basic elements are
available in 300 mm and 500 mm lengths. Integration
into existing conveyors is easy.
Basic denirug elements are used to support modular
belts instead of runners, wooden pallets etc. As a result, rolling friction saves at least 90% of the drive
power and smaller motors can be used.
denirug modules
denirug modules are ready-for-use modular belt sections with integrated basic denirug elements. By using
a rocker, users can combine them very easily to produce smooth-running sections of conveyor in almost
any length and width. denirug modules are available in
800 mm and 1200 mm lengths. They can have guide
rails at the sides. Other additional components are also
available. Available as a single component, the rocker is
required for assembly and for fast and easy compensation of uneven sections.
