Overload protection ”OLP” , warning signals
Figure 1
Olsbergs hand controllers can provide informa-
tion about the pressure in cylinders equipped
with pressure sensors. This information is linked
directly to each function.
The pressure is shown as a percentage of the maxi-
mum pressure permitted, furthermore it also shows
if a particular motion is prohibited or if the crane is
subject to overload protection, (OLP).
There are three types of OLP:
Crane-OLP: means that the crane is under
maximum load.
Outrigger-OLP: means that one of the outriggers
of the crane or vehicle is under
maximum load.
VSL-OLP: means that the stability limit of the
crane or vehicle has been reached.
Overload is shown on the hand controller’s displays
as follows.
CRANE-OLP
Indicated by showing 100% for those functions that
have pressure sensors in the cylinders. Any movement
that would increase the load is blocked. (Figure 1)
OUTRIGGER-OLP
Outrigger-OLP means that one of the outriggers is
under maximum load and a symbol is shown in the
centre display with the actual outrigger crossed.
At outrigger-OLP this symbol is shown irrespective
of which menu is shown in the centre display. Out-
rigger-OLP ”front left” or ”front right” are indicated
at the same spot on the symbol in the centre display.
VSL-OLP
VSL-OLP means that the stability limit of the crane/vehicle
has been reached and VSL is indicated on the centre display.
If outrigger-OLP and VSL-OLP occur at the same time, VSL
is indicated in the same symbol as the outrigger OLP.
At all types of OLP the crane/vehicle stops and all levers
must be moved to neutral position before the crane/vehicle
can be operated out of OLP position and the central display
returns to normal.
<=>
Regardless of which menu is active Outrigger – OLP
will be shown. Here outrigger-OLP ”-mid left”.
VSL-OLP
Outrigger-OLP
