5.5.2.3 Fixation of derricking traveling block
The machine is fitted with an automatic positioning device for derricking travelling block, which
is convenient for dismantling of the pulley block. Taking the fixation of derricking travelling block
as an example, illustrate the usage method of the device.
When the basic machine is prepared for conversion, the boom frame should be lowered to the
ground. At this time, dismantle the connection between the travelling block and anchoring rod.
When main boom head is in contact with the ground, unwind the derricking rope to lower
derricking traveling block (part 3 in the figure 5-58) slowly.
Under the pulling of main boom anchoring rods, the derricking travelling block will move above
the guide board (part 2).
Continue to unwind the derricking rope so that the guide rod (part 1) on the derricking travelling
block comes into contact with the oblique plane of guide board (part 2), thus guiding the
derricking travelling block to lower down to the required position.
When the pin spindle (part 5) on the derricking travelling block (part 3) is aligned with the
mounting hole on the main boom pivot section, mount the pin spindle. Disconnect the cross
coupling (part 4) on derricking travelling block (part 3) from main boom anchoring rods, rotate
the left and right cross couplings 90° to the same direction and fasten them (see figure 5-59). At
this time, the derricking travelling block is fastened on main boom pivot section. The relevant
parts can be seen in the table 5-15.
