2250 MAX-ER 2000 OPERATOR’S MANUAL OPERATING CONTROLS AND PROCEDURES
3
Traveling and Swinging
The following travel and swing instructions apply only when
the MAX-ER wheels are on the ground.
The wheels are positioned using the MAX-ER remote control
switches to release the steering pins, to move the steering
arms and to engage the steering pins. The steering arms and
pins must be properly positioned depending on swing radius
and type of travel or swing.
Stop Pin Positions
See Figure 3-19, Views B and C. Letters identifying pin holes
in Table 3-2 refer to inner holes on steering arm.
Table 3-2 Stop Pin Inner Hole Positions
Straight Travel /Turns
See Figure 3-19 for following procedure.
1. Swing upperworks and wheeled counterweight
assembly in-line with crawlers (perform Swinging steps).
2. Raise counterweight with jacking cylinders until bulge is
out of tires.
3. Disengage steering pins (Pins 3, View B).
4. Set stop pins (see Table 3-2).
5. Rotate wheel assemblies until Pin 4 hits stop plate
(straight position) (View D).
6. Engage steering pins (Pins 3) in outer Holes E. Some
movement back toward swing position may be
required to align holes.
7. Retract jacking cylinders.
8. Disengage swing lock and release swing brake.
9. Proceed to travel forward or in reverse.
Turns while traveling straight are permitted in forward
direction only. Watch tires closely during turn. If tire
scraping is excessive, reduce radius of turn.
Crab Travel
NOTE: On current production cranes without a swing lock,
crab travel is not allowed.
See Figure 3-19 for following procedure.
1. Pin wheels in straight position (perform Straight Travel
steps).
2. Disengage swing lock and release swing brake.
3. Counter-rotate crawlers 90
°
to crane upperworks. Crane
upperworks must be 90° to crawlers to prevent
damage to swing drives.
4. Raise counterweight with jacking cylinders until bulge is
out of tires.
5. Disengage steering pins (Pins 3, View B).
CAUTION
Machinery Damage!
Counterweight trailer must be supported on jacks before
changing wheel position:
• Check that strut and drawbar pins are in proper
positions (see Figure 3-20). Hydraulic cylinders and
other wheeled counterweight assembly components
may be damaged.
• Extend jacks to bear most of counterweight trailer
load (until bulge is out of tires). Failure to do so may
cause tires to separate from rims as wheels are
positioned.
