The
PULSE
TerraMetrix RS Shovel
Management System was developed to
address the accuracy issues commonly
associated with shovel based payload
monitoring systems.
Unlike other payload monitoring systems
which rely on electrical parameter
measurements to approximate the payload
as a quasi-static process, the
PULSE
TerraMetrix RS system employs a loadcell
to directly measure the inertial and
dynamic loads applied to the dipper.
As a result, accurate payload
measurement is maintained even under
severe dynamic loading conditions.
Calibration trials completed at several
mine sites in North America have
confirmed that the
PULSE
TerraMetrix RS system repeatedly
achieves accuracy levels
exceeding industry norms.
Proof of calibration data is
available on request.
The net payload displayed by the system
allows the operator to employ smart
loading strategies: if the truck is under
loaded by more than 1/2 a dipper load
then an additional pass can be executed
to achieve the target load.
With this ability, truck dispatch can be
initiated by the shovel operator when the
target load is achieved. Although truck
dispatch has been introduced
based on truck weightometers,
due to strut friction, truck
weightometers are not
sufficiently accurate to
implement this form of
strategic loading control at
the shovel in real time.
Truck weightometers only achieve
sufficient accuracy (if well maintained)
once the truck has travelled some distance
away from the shovel and the strut friction
effects have dissipated.
