Modular Belt Conveyors
Application Options
Due to their positive locking drive in the side rail,
modular conveyors are recommended where a belt
is not an option due to slip, an unfavourable lengthwidth
ratio or transverse forces. The low-maintenance
plastic modular belts in Series 8 and 10
(straight) and ASB 2.2 (curve) are standard versions.
Upon request, we can provide a design with reinforced
bearings, supplemental supports of the
drive shaft and an appropriate number of additional
sprockets to utilise the full performance capacity
of the chain and, following testing and coordination,
enable widths of up to 2 m.
Conveyor with a hinged steel belt
The hinged plate belt for the incline conveyor is
equipped with a steel chain that makes it suitable
for harsh environmental conditions and for transporting
products such as stamped, cast, forged
or wooden pieces. It is particularly suitable for conveying
hot goods up to 200° C.
On request, transverse cleats can be screwed or
welded on. Stainless steel or perforated variants of
the chain are available. Due to the gap of 1 to 3 mm
between the side rail and chain, this system is not
suitable for pointed stamping scraps or metal chips.
Modular Belts
Series 8 is characterised by its robustness and is
used in industrial applications in particular. Series 10
is intended for transporting lightweight to mediumweight
products in sanitary environments, such as
those found in the food industry and the pharmaceutical
sector. The module geometry and the
sprocket wheels were therefore designed to ensure
easy cleaning, to eliminate cavities and hollow
spaces and to allow for limited self-cleaning of the
gaps.
Transverse cleats up to 75 mm in height and side
plates up to 100 mm in height are available for both
series. This eliminates the need for a complex side
rail, as well as the associated problems arising
from gaps and from relative motion between the
chain and side rail.
For the permissible tensile load, a safety factor of
three relative to the permissible tensile loads of the
chain was included in the calculation to ensure
reliable durability. At a length of 3 metres, the usual
chain slack can be dispensed with, which allows
for restricted reversing operations. At lengths
of more than 3 metres or under heavy loads, the
conveyor is run with a balance option (e.g. chain
sagging or a tensioning device).
The chain for curves (ASB 2.2) is highly resistant
to wear and abrasion, making it suitable for high
temperatures, contact with chemicals or food, etc.
Modular Belt Material
The Series 8 chain made from impact-resistant,
affordable polypropylene (PP) is the standard for
industrial applications. Series 10 is made from
polyethylene (PE) for applications in the food
industry.
For especially demanding requirements regarding
max. load and/or cut resistance, we recommend
polyoxymethylene (POM, POM-CR). This material
can even handle the occasional impact from
product landing forcefully on the chain or the
transverse cleats.
