Torque limiter type
ECA for belt drives
APPLICATIONS of torque limiters can
be found in all sectors of technique, in
any machine or facility where torques
have to be limited to protect machines
or products from overload.
The torque limiter type ECA, which
is especially engineered for belt drives
prevents such overload damages or
at least reduces them to a minimum.
Particular value was put on compulsion-
cutting and a fast switching function.
Simple, light elements avoid adverse
dullness of mass or switching. They were
chosen because too-heavy switching
elements could considerably increase
the (static adjusted) disengagement
torque in case of a dynamic
collision and therefore also the
destructive collision forces.
In contrary to conventional
friction clutches the ECA has
a very high repeatability of
the adjusted disengagement
torque. It is free of clearance and self-
reliantly re-engages after one turn.
The movement of switching can
be sampled by a proximity switch.
Seventeen design sizes make a total
torque range of 0.5Nm to 470Nm
overall.
The ECA forms a very compact
unit together with a crown gear and is
deliverable in diverse versions (with
keyway or conical bush).
The ECA is significant because it
is one of the smallest torque limiters
available on the market.

Stacking and bundling system
from ASMAG
WHEN working with round, hexagon,
squared or rectangular bars and tubes,
stacking and bundling is an involved
process. Changing from round to
hexagon bars and from one size to
another is where traditional systems
take time and manual work.
Asmag, headquatered in Scharnstein,
Austria, has developed a new
automated method. Asmag discovered
that manually adjusting the stacking
machine each time dimensions or
shapes changed was unnecessary.
Operators typically spend a few
minutes for each time they must replace
inserts to accommodate changing
hexagon bar sizes or when an insert
must be removed altogether to switch
from hexagons to rounds.
In regard to the tendency to smaller
lot sizes, this normally causes changing
the inserts once an hour. Another
disadvantage is the purchase, storage
and maintenance of the insert-sets for
each product size. The new system
eliminates that step.
Usually the cams are necessary
because hexagonal material tends
to tilt at the wrong angle. The Asmag
innovation makes sure that the bars in
the first layer fall into the right position.
This system is based on a simple idea
but it has not been used before.
In addition, software automatically
calculates several possible bundle
shapes and sizes and then determines
whether three or four bars in a layer
at the bottom would be the best
configuration based on production
orders. This innovative system was
tested in a customer’s complete new
production line.
Asmag’s in-house manufacturing
features such capabilities as design,
mechanical and electrical engineering,
production of components, assembly,
testing of machines, production of switch
cabinets and programming of machines
and entire lines. Having that kind of
control over such processes helps the
company to guarantee quality control for
complete lines and create new custom
solutions.

Vacuum lifting system
THE Starlift vacuum system from
Acimex handles tubes, pipes (concrete,
steel and cast-iron), tanks or any other
cylindrical device.
Handling by suction cups is a safe
way to move products without any
mechanical contact.
A rubber gasket ensures a soft
touch without leaving any marks or
deformation of the pipes.
A single operator carries out both
driving and remote handling operations
on either an excavator or a forklift crane.
Remote control ensures 100 per cent
security. Quick and efficient installation
also increases productivity.
