wedish crane scale producer,
Intermercato, has developed
a new compact crane scale
for material handlers, excavators,
stationary log loaders and truck
mounted timber cranes.
The Intelweigh Compact
MH scale is one big monolith
without moving parts, bringing
maintenance to a minimum. The
round 395 mm massive scale body
is not more than 140 mm high (10
t) and 170 mm (15 t), which renders
both stability to the lifting process
as well as it reduces the movement
of the boom.
A scale for a middle size
excavator or a stationary log
loader would typically have a
measuring range of 10 t (Intelweigh
Compact MH 10), which means it is
dimensioned for 30 t.
Over the years Intermercato
scales have been used in scrap
recycling. Normally these scales
are mounted on machines like
Liebherr, Sennebogen, Fuchs etc.
Due to the extreme impact on
scrap handling equipment, the
challenges for these scales are
enormous.
Weighing must be possible in
movement as there is no time to
stop the machine and wait for a
weighing result. The scales must
resist forces from all sides, not only
generated by the load itself but
also from negative loads (pushing)
and last, but not least, it must
resist considerable radial forces.
The multiple strain gauge
technology in combination with
Intermercato’s unique algorithm for
calculation of weight in movement
makes accurate weighing possible
even under the most challenging
conditions.
In developing the design, the
manufacturer had to grapple with
the question of whether it was
actually possible to produce a
unit both rugged and accurate. In
spite of its sturdy construction,
the Intelweigh Compact has a
surprisingly high resolution. Before
delivery a 10 t scale is pushed
through a calibration program
made up by approximately 80,000
units.
The Intelweigh Compact scale
can easily be adapted to any loader
and any rotator/grab. It can be
bolted directly on a flat top rotator,
