(2) After crawler carrier is assembled on the undercarriage central section via
mounting cylinder, the angle of main boom pivot section is large. At this time, pivot
section may not be lowered by unwinding the derricking rope. It must be lowered by
the weight of lifted load.
(3) The self-assembly operation must be performed by at least three persons. Before
operation, everyone must acquaint himself with self-assembly operation, and define
the responsibilities during operation.
(4) All the operation must be carried out slowly during self-assembly process.
5.2.2.2 Unloading of crawler carrier
Lift crawler carrier via mounting cylinder, and then move it to the required position.
a) After derricking mechanism is installed, remove the pin spindle which is used to connect
inner pipe and outer pipe of main boom tilting-back support, loose the mounting cylinder
from main boom pivot section, and establish hydraulic connection of mounting cylinder.
b) Adjust the support cylinders to ensure that the inclination of machine does not exceeds 1%,
and the distance from the base plane of undercarriage central section to the ground does
not exceeds 2'2" (650mm).
c) Stop the low-loader with crawler carrier attached beside the basic machine, slew
superstructure for 90°, and then lift crawler carrier via mounting cylinder as shown in the
figure 5-9.
d) Move crawler carrier to required position, and align the connecting hole of crawler carrier
with the hole of undercarriage central section. At this time, the angle of main boom pivot
section is 76°, and the working radius of load is 9'2" (2800mm).
