Aufzugsystem für Überlastschutz und mehr
Elevator system for overload protection and more
Die Engineering-Teams des Unternehmens
Zemic haben nach eigenen Angaben die
effizienteste und kosteneffektivste Lösung
zur Überlast-Erkennung für Aufzüge und
Hebesysteme entwickelt.
Zur Entwicklung einer neuen und inno-
vativen Lösung für den Überlastschutz
von Aufzügen arbeiteten die Engineering-
Teams von Zemic mit den wichtigstenAuf-
zugherstellern zusammen. Für Aufzugher-
steller ist das Thema Überlast von großer
Bedeutung. Noch besser wäre es jedoch,
The engineering teams at Zemic have
worked together to make the most ef-
ficient and cost effective solution for
overload detection systems for elevators
and lifting systems.
The engineering teams at Zemic worked
together with key elevator manufacturers to
develop a new and innovative solution for eleva-
tor overload protection. The elevator manufac-
turers indicated that overload is a main feature,
however it would be more optimized when this
could be combined with topics such as energy
savingmotor management and child protection.
Besides functional requirements the engineering
teams were challenged by specific product de-
mands such as shape of the loadcell, installation
requirements and specific market requirements.
Zemic introduces three weighing kits based on
three different ways lift / elevator companies are
measuring the weight. We offer complete solu-
tions tomeasure theweight under the cabin, un-
der the cable springs and into the cable springs.
Zemic and the Elevator Market:
• Elevator weighing system
• Selected most efficient solution
• Elevator motor management for energy saving
• Zemic Europe, force partner of the Elevator
Industry
The Zemic ElevatorWeighing systems havemany
features. Zemic will mention the unique selling
points of the system to show why and how this
particular lifting system is used throughout the
world. Energy saving is one of the extra require-
ments which was highlighted. This is the reason
the engineers built in the power regulation op-
tion for the elevator engine. The power needed
to drive the engine depends on the amount of
loading weight in the elevator.
In the elevator industry overload indication is one
of the key features in each lifting device. Force
sensors are highly sensitive and can be perma-
nently damagedby overload and shock overload.
This is why the maximum overload % is always
given on the force sensor product datasheet.
When developing this sensor we integrated a
rubber shock absorber. This elastomer protects
the loadcell from dynamic overload forces and
secondly provides an equally shared load over
the sensors.
Some unique features of the elevator force sen-
sors is the round shape for an optimized force
introduction and thematerial used. The working
of the loadcells do not depend on the angle of
the force introduction. The round shape allows
you to compensate non-axial force effects. The
loadcells are suited with a cable spring fitting
on the cable exit which protects the wires from
bending and breaking, which increases the

wenn der Überlastschutz mit weiteren
Merkmalen wie zum Beispiel Energiespar-
Motormanagement und Kindersicherung
kombiniert werden könnte.
Neben den funktionalen Anforderungen
bestand für die Engineering-Teams die
Herausforderung in spezifischen Produkt
anforderungen wie Form der Wägezelle,
Einbauanforderungen und spezielle Mark-
terfordernisse.
Zemic stellt drei Wägekits vor, mit denen
Hersteller von Aufzügen das Gewicht auf
drei verschiedene Arten erfassen können.
Das Unternehmen bietet Komplettlösun-
gen zur Messung des Gewichts unter dem
Kabinenboden, unter den Zugseilfedern
und in der Zugseilbefestigung der Kabine.
