T
he grip is one of the key components
of any ropeway. It is the element that
connects the carrier to the rope. Safety
is the utmost priority on this component,
which is why top precision is called for in the
manufacturing process. This is made possible
by modern and efficient production methods.
Doppelmayr customers benefit from the decades
of experience and know-how in the development
and manufacture of grips.
Efficient assembly
The fully automated grip manufacturing line
incorporates cutting-edge technology plus a
host of digital features. The work steps are
precisely tuned to one another and each operative
has their defined work area. In the first
step, the grip components – some of which
are preassembled, such as spring packs, grip
levers, running wheel plates along with pins
and bolts – are assembled by an operative.
Comprehensive data is recorded for every individual
grip assembly group. All screw tightening
torques are transmitted by W-LAN with
the aid of a special torque wrench and automatically
documented electronically. Following
assembly, the quality control is performed
in two steps: First, an industrial robot scans
the entire grip down to the smallest detail and
performs the first function test, which is electronically
monitored. For the final inspection,
an operative carries out all the inspection steps
once again and saves them electronically. A
second, final function test is also performed as
part of this step.
Transparency and full traceability
Digitalization and the complete recording of all
data bring many benefits. This provides valuable
information for preventive maintenance of
grips – throughout the entire life of the grip.
Transparency, short routes, the availability of
all parts, traceability and the provision of all
the relevant information are important prerequisites
for a sustainably efficient production
process – and the same goes for the grip
manufacturing line.
