It’s not just the doors – it’s also where
you put them. “A total of 65 high-speed
doors are installed at heavily used
entrances in order to optimize material
flow to the manufacturing lines and
effectively deal with the logistics
transfer,” explains Rainer Volke, the
engineer responsible for all building
maintenance and management at
Jungheinrich Moosburg AG & Co. KG, in
the town of Moosburg, Upper Bavaria.
They make traditional forklifts here
and high-speed doors from Efaflex
have been doing their job for many
years. “For us, it is the best provider
on the market,” says Rainer Volke.
“The robust, long-lasting and quick
door systems fulfil their function
perfectly. Our geographical proximity
to the door manufacturer is also a
significant benefit for servicing. From
experience, someone is always on site
quickly if routine maintenance needs
to be carried out. For example, with
such a large number of doors installed
parts are necessary from time to time,
particularly during cold periods.”
It is very important that logistics routes
are reinstated promptly and any parts
necessary are available quickly in order
to guarantee an unlimited, efficient
flow of materials and to avoid affecting
the overall logistical processes.
Jungheinrich sets a high benchmark for
the whole package of products, service
and spare parts: “In comparison with
the competition, Efaflex is noticeably
strong in consulting services, very
flexible technologically and offers
doors and controls with absolutely
individual customisation for every
differing requirement, as well as
offering very large dimensions,” Volke
continues. “In our internal logistics,
for example, we need special controls
for fully automated, monitored roller
conveyor systems, while for the
building envelope, the doors’ burglary

high thermal insulation and
functional reliability are all important
considerations for us. We absolutely
don’t want to waste valuable energy.
“Most importantly though, our doors
have to be quick and safe. By safe, we
mean that the doors can still react if
drivers are driving too fast.”
The laser scanner approach area
protection is therefore installed on
four of the door systems. “It works
brilliantly,” enthuses Volke.
The patented EFA-SCAN® laser
scanner was developed by engineers
as the world’s first laser scanner for
horizontal use on high-speed doors.
The compact device, easily installed
in a protected location, constantly
captures the entire area in front of the
door and combines intelligent motion
detection and reliable approach area
protection into one.
The scanner reacts quickly within the
dynamic detection zone - if a moving
object is detected, the technology

triggers the door to open in a fraction
of a second. The geometry and
logic for this detection area can be
individually programmed up to a
maximum of 10x10m, on site with a
remote control. The laser scanner
detects every movement and at the
same time also evaluates the distance,
direction and speed to optimize the
“pinpoint” opening impulse. However,
this does not occur if vehicles or
people are simply passing along the
frontage. Directly in front of the door
the laser generates a safety field of a
variably adjustable depth in which the
EFA-SCAN® extensively protects the
full width of the door and prevents the
door from closing as soon as it detects
a moving or stationary obstacle It
therefore protects against accidents,
while also preventing damage to the
door.
Complex software algorithms prevent
the scanner from being falsely
triggered by rain, snow or extraneous
light. It scans the horizontal with a
detection angle of 95 degrees and
additionally scans the same area 6
degrees in the vertical. With 16,000
measurements every second, nothing
escapes the laser scanner.
