5.2.2.3 Assembly of left crawler carrier
Procedure for assembling left crawler carrier:
Figure 5-10 Assembly of left crawler carrier
a) Affirm that four pairs of folding brackets have been positioned by retaining plates (part 4 in
the figure 5-17), and the adjusting blocks on the folding brackets have been removed to
the lowest position. Otherwise, it will be difficult to assemble the crawler carrier.
b) Adjust the position of crawler carrier via slewing mechanism, and the height of crawler
carrier via derricking mechanism and mounting cylinder. Align the mounting holes of
crawler carrier with those of undercarriage central section. (See the figure 5-10)
c) Attach crawler carrier onto the undercarriage central section with the help of mounting
cylinder and main boom pivot section.
If it is difficult to move the crawler carrier, the operator must first check whether there is an
object hindering the operation, and then adopt the auxiliary device mentioned in step d) to
move the crawler carrier.
d) Extend left horizontal cylinder (part 1 in the figure 5-11) to make the piston rod pass
through the hole in the middle of crawler carrier. After piston rod passes through the
retaining plates (part 3) in the hole, mount a pin spindle (part 2) on the piston rod, and
slowly retract the horizontal cylinder. At this moment, the pin spindle will catch the retaining
plates so as to pull the crawler carrier towards the direction of undercarriage central
section.
e) Move the crawler carrier to a proper position where it is 6'11"(2100mm) from the central
line of undercarriage central section with the help of main boom pivot section, mounting
cylinder and horizontal cylinder. Adjust the height of support cylinder to make crawler
carrier come into contact with the ground.
f) Remove the pin spindle (part 2) from the horizontal cylinder, and extend horizontal cylinder
to its working position. See the figure 5-12.
