Handling’s
new
generation
of Demag DIR infrared
(IR) remote controls
provides crane operators
with a viable alternative to
conventional radio controls.
The Demag DIR range
incorporates a variety of
innovative features for
the reliable and efficient
control of material handling
systems.
One of the principal
advantages of the
Demag DIR system over
radio controllers is the
considerably shorter
range, of some 40 metres
between the transmitter
and sensor(s), which is of
benefit when the operator
wants to limit the distance
at which the crane can
be controlled, for safety
reasons. This specifically
limited range ensures
that operators are always
in close proximity to the
equipment, providing a
clear view of the lifting and
moving process. There is
no risk that the IR control
system will be influenced
or impaired by radio
systems and the IR offers
no potential for interference
with other radio controls.
The Demag DIR’s rugged
hand held transmitter
housing is based on the
design used for Demag
radio controls, meaning
that users will be familiar
with the controller layout
and can use the same
keypad concept for both
transmission methods. DIR
hand held transmitters
are offered in two sizes
for two stage control, with
six buttons (DIR 6) and
ten buttons (DIR 10) for
the control of two or three
motion axes, respectively.
Like Demag radio control
systems, up to ten crane
systems may be controlled
simultaneously in an
enclosed area. For multiple
controller operation,
switchover between
transmitters is monitored
to ensure that the control
systems are clearly assigned
to specific cranes.
The high contrast bi-colour
display provides a clear
overview of the device and
warning information, which
affords the highest level
of safety. The integrated
vibration alarm and stop
function conform to
Category 3, Performance
Level ‘d’ to the relevant
standard EN 13849-1.
Convenient and simple
crane control is assured at
short distances, of up to 15
metres, as the rays from the
high performance infrared
LEDs are reflected by the
surrounding structure,
eliminating the need for the
transmitter to be pointed
directly at the sensor.
High performance
rechargeable batteries
ensure operating times of
up to 30 hours with one
charge. The unit can be
conveniently charged on
an optional inductive
charging station.
In addition to
providing reliable
wireless control of
industrial cranes,
the Demag DIR
may also be
used to control
suspension
monorails, transfer
carriages and other
materials handling
