Install Crawlers
See Figure 4-17 for the following procedure.
First Crawler Installation
1. Position the trailer (1) carrying the crawler (2) either
parallel or perpendicular to the carbody, as long as the
maximum radius is not exceeded.
2. Swing the rotating bed (3) so the assembly block (4) is
centered over the crawler.
3. Connect the crawler handling chain assembly to the
hook of the assembly block.
4. Connect the three legs of the chain assembly to the
lifting lugs (5) on the crawler frame (see View A).
5. Lift the crawler clear of the trailer.
NOTE: The crawler will hang at an angle, which allows the
top connecting holes in the crawler to easily
engage the top pins in the carbody (6).
6. Remove the trailer from the work area.
DANGER
Tipping Hazard!
Avoid death or serious injury. Prevent the crane from
tipping over:
• Make sure the crane is level. Adjust the jacks as
required.
• Limit the swing to 5° in either direction from center
when lifting the crawler.
CAUTION
Parts Damage!
Avoid hitting the carbody jacks with crawlers.
