RIPPING BY CLIFFS 3
q
When carrying out ripping at the edge of a cliff, tilt the rip-
per back to make depth (L) longer.
q
Depress the decelerator pedal, drive slowly forward, and
when the ripper point contacts the cliff, tilt the ripper.
RIPPING BY SLOPE FACES 3
(Giant ripper)
q
When carrying out ripping work at the edge of slope faces,
make the ripper tilt back angle small, and if there is an area
where the slope face has not been ripped, apply the ripper
diagonally.
REMARK
In the case of the multi-shank ripper, carry out ripping at right
angles to the slope face.
Cross ripping
q
On jobsites with hard bedrock, for rocks and boulders
which are impossible to break or dig up with one ripping
pass, carry out the second ripping pass at right angles to
the first ripping direction.
q
At the edge of cliffs, where it is impossible to apply the rip-
per in a cross direction, make the space between the
shanks smaller and carry out ripping.
q
During the ripping operation, if there is any hard bedrock,
carry out ripping in the opposite direction to the direction
where the ripper was applied. If it is still impossible to
break up the rock, break up the area around the bedrock a
little at the time.
q
When carrying out concentrated ripping of hard bedrock,
the work efficiency is high if the ripper is applied to the
whole of the digging face.
