Start Engine
Perform the pre-start checks given on page 4-7 and start the
engine.
Configure RCL/RCI for Crane Setup
Select the Boom Butt Configuration in the RCL/RCI display.
The block-up faults will come on at start-up and remain on
until this step is performed.
Raise Gantry
See Figure 4-8.
Manitowoc recommends that the gantry be raised while the
crane is on the trailer.
1. Hold the counterweight links (1, View A) so they cannot
fall when the pins are removed.
2. Remove the safety pins (2, View E), the collars (3), and
the pins (4).
3. Lower the counterweight links to vertical.
4. Reinstall the safety pins (2, View D), the collars (3), and
the pins (4) in the holes in the counterweight links (1).
The pin heads should be on the inboard side of the links.
5. Using the gantry cylinders switch on the right console in
the cab, extend the gantry cylinders (6, View B) to raise
the gantry.
6. The boom hoist wire rope will slacken as the gantry
rises. Haul in the wire rope with the boom hoist control in
the cab only enough to remove the slack.
7. Continue to raise the gantry until the cylinders are fully
extended and the backhitch links (7, View C) are tight.
Travel Crane off Trailer
See Figure 4-9.
1. Verify that the boom hoist wire rope is spooled properly
on the boom hoist drum.
2. Raise the boom butt to no higher than horizontal.
If the front load line (8, View A, Figure 4-8
) is stored on
the boom butt, keep it slack as the butt rises.
3. Slowly travel the crane off the trailer.
4. Remove the trailer from the assembly area.
360° swing is permitted once the crane is off the trailer.
CAUTION
Avoid Wire Rope Damage!
If you chose to travel the crane off the trailer with the
gantry down, the boom hoist wire rope will rub against the
cross brace on the gantry and possibly against the wire
rope on the rear drum when the boom butt is raised.
Premature rope wear will occur, resulting in shorter rope
life.
To raise the gantry, the boom butt must be at least 457
mm (18 in) above the trailer deck (View A). Otherwise,
wire rope damage can occur.
WARNING
Tipping Crane Hazard!
To prevent tipping, do not swing (keep upperworks inline
with lowerworks) until the crane is traveled off the trailer.
CAUTION
Avoid Sheave Damage!
Use extreme care while swinging so the rope guide under
the boom butt does not hit the crawlers (or carbody
counterweight once installed).
