14000 OPERATOR MANUAL SETUP AND INSTALLATION
Install Assembly Block
See Figure 4-11 for the following procedure.
NOTE: Manitowoc suggests that assembly block (3) be
shipped on the same trailer (1) as a crawler (2).
Assembly personnel can then stand on the deck of
the trailer or the crawler when reeving the block.
1. Position crane and trailer (1) as follows to provide
access to mast point sheaves:
a. Fully retract jacks (keep crane as level as possible
while jacking).
b. Raise jacks on side of carbody opposite mast not
more than 8 in (203 mm). This step will tip mast
down.
c. Lower mast to 172°.
2. Position trailer (1) as shown in View A.
3. Reeve wire rope from rear drum (5, View B) through
center sheave (6) in mast point and sheave in assembly
block (3).
4. Anchor wire rope to socket and wedge (4, View A) (see
Wire Rope Installation on Page 98
for instructions) and
connect socket and wedge to lug (7) on mast.
5. Extend jacks so crane is level and carbody is at least 2 ft
(0,6 m) off ground (View D).
6. Raise mast to lift assembly block (3) off trailer (2) and
position mast in operating range (View D).
7. Connect 4-leg chain sling (8, View D) to assembly block
