Install First Crawler
See Figure 4-34 for the following procedure.
1. Position the trailer (1, View C) carrying the crawler (2) on
the desired side of the crane at the specified radius.
The side of the crawler with one lifting link must face the
crane.
2. Remove the tie-downs and blocking securing the
crawler to the trailer.
3. Swing the upperworks so the self-erect cylinder (3) and
lifting slings (4) are centered over the crawler.
4. Connect three legs of the lifting slings (4, View B) to the
lifting links (6) on the crawler with shackles (5).
5. Retract the self-erect cylinder until the lifting links (3,
View B) start to rotate up.
6. At the inboard lifting link (6, View A):
a. Remove the hitch pin (7) from the bottom holes (8)
in the bracket.
b. Lift the inboard link (6).
c. Reinstall pin (7) in the TOP holes in the bracket.
d. Lower the link (6) onto the pin (7).
The inboard lifting link will interfere with crawler pin
installation if this step is not performed.
7. Continue to retract the self-erect cylinder to lift the
crawler (2) clear of the trailer (1, View D).
NOTE The crawler will hang at an angle as shown.
8. Remove the trailer.
9. Remove the collars (9, View E) from both crawler pins
(11).
10. Temporarily store the collars on the storage lugs (12,
View E).
11. Using the remote control, disengage the corresponding
crawler pins (11).
12. Tilt the operator cab up so it is not damaged during
step 13
on the next page.
DANGER
Tipping Hazard!
Prevent the crane from tipping over:
• Make sure the crane is level. Adjust the carbody jacks
as required.
• Make sure the small diameter rods of the jacking
cylinders are fully retracted before handling the
crawlers, otherwise the jacking cylinders will be
overloaded and possibly collapse.
• Limit swing to 30° in either direction from center when
lifting the first crawler (see Figure 4-35
).
• Do not exceed a radius of 5,7 m (19 ft) when lifting
first crawler.
CAUTION
Parts Damage!
Do not attempt to lift the crawler off the trailer by booming
up. Damage to the self-erect cylinder can occur.
Avoid hitting the carbody jacks with the crawler.
