5 WORK OPERATION
5.10 MHL380 D
5.1.10 Close range cut-off (dipperstick)
When the dipperstick is moved (retracted) in
the direction of the cab, the grab or the load
that has been taken up may collide with the
cab due to driver error.
To reduce the risk of collision, the range of
motion of the dipperstick in the direction of the
cab is restricted by an electrical close range
cut-off function.
When the close range limit is reached, an
inductive proximity switch on the dipperstick
joint triggers disabling of the dipperstick.
The close range cut-off function is not a
safety device! It is only intended as an aid
for the operator!
For all parts of the loading equipment, in-
cluding load, a minimum safety distance of
1.5 m from the cab must be observed.
Danger of injury due to collisions
Collisions may arise due to:
- (load hook, grab, etc.) or because
of differences in dimensions in work
attachments when they are open as
opposed to closed.
- due to overhead load.
- because of a delay in the shut-off.
Depending on the oil temperature
and equipment configuration, the
cut-off path can be extended by up
to 0.5 m, and depending on the re-
tracting speed and grab content by
up to 1.0 m.
• A minimum safety distance of
1.5 m from the cab must be ob-
served.
• Risk of damage! Avoid rapid mo-
tions of the dipperstick if you are
moving it close to the cut-off
points.
In an emergency: Administer first
aid, seek treatment from a doctor
