The operation of retracting crawler carriers is shown as follows:
Figure 5-22 Crawler carrier retracted completely
a) Lower the adjusting blocks of eight folding brackets via socket wrench to proper positions
where the adjusting blocks are in the same level with the upper plane of folding brackets.
b) Pull out the positioning pins of horizontal anchoring rods so that the anchoring rods can
move with the retracting of crawler carriers.
c) Retract left horizontal cylinder to pull left crawler carrier in. After left crawler carrier is
retracted to the required position, insert the positioning pin of left horizontal anchoring rods.
Retract right crawler carrier to required position, and then fix it well.
d) After the left and right crawler carriers are retracted completely and the horizontal
anchoring rods are mounted, take out the retaining plate on the folding bracket, and then
put it on the hook of the crawler carrier.
e) Swivel four pairs of folding brackets to proper positions so that the crawler carrier can be
retracted completely. Fix the folding bracket on the crawler carrier by a positioning pin.
DANGER
(1) In any cases, the extending and retracting of crawler carrier must be carried out by
at least two persons. During operation, one person operates the control levers, the
other checks if the crawler carrier is extended in the required position, and ensures
that the horizontal cylinder moves smoothly.
(2) After crawler carrier is extended or retracted properly, insert the pin spindle into the
horizontal anchoring rods before traveling.
(3) The engine speed must be controlled within middle-low range (900 rpm-1400 rpm)
during extending and retracting of crawler carrier.
For reference only.
Operators manual should be consulted and adhered to.
