1
Detection of truck position on the
crusher
As haul trucks unload their cargo, it
is imperative that they are properly
positioned above the crusher. Too far
away means the load will be dumped
at the edge of the crusher, while too
close could land the truck in the crusher.
The RMS3xx radar sensor assists the
driver to properly align the vehicle with
the crusher’s opening, even in harsh
conditions like snow, fog and dust. The
RMS3xx, mounted at the rear of the
truck can detect both static and moving
objects, allowing the driver to correctly
and efciently unload the haul into the
crusher. Alternatively, installed on the
crusher, the Visionary-B CV can be con-
gured to issue an alert if haul trucks
deviate from the optimal positioning.
The Visionary solution can also monitor
the danger zones around the crusher to
ensure that no vehicles or personnel are
present in the area before starting to
operate.

Detection of tray position for dust
suppression
Once a truck unloads its haul, a sprin-
kler system should be triggered to sup-
press the resulting dust cloud. Knowing
when to initiate the suppression system
and optimizing this elimination process
relies on exact timing. Mounted on the
frame at the crusher’s tray, the RMS3xx
radar sensor can be congured to
monitor movement. The sensor can ac-
tivate the crusher’s sprinklers, thereby
increasing the rate at which subsequent
trucks can unload their payload.

Crushermonitoringandoverllprotection
An overlled crusher is not efcient
for optimal unloading of material. An
MRS6000 LiDAR sensor mounted on the
frame above the crusher monitors the ll
level while also being linked to a warning
system that issues an alert in the event
of a jammed or overlled hopper. The
MRS6000 generates a 3D point cloud
of the crusher’s load, concentrating on
the region of interest and compacting
all scan points to the front of that point,
thus allowing a better integration and
processing. Its special mirror technology
results in a highly regular spot pattern
and uniform measurement.
