Install Intermediate Suspension Strut
See Figure 4-67 for the following procedure.
NOTE An assist crane is required for this procedure.
The intermediate suspension strut weighs
approximately 551 lb (250 kg).
The chain lifting sling supplied by Manitowoc can
be used to lift the intermediate suspension strut at
the lifting lugs (8, View C).
The intermediate suspension strut is symmetrical
from side to side.
1. Determine the correct installation position of the
intermediate suspension strut. See the Boom Assembly
Drawing and the Intermediate Suspension Strut
Assembly Drawing at the end of this section.
2. Unpin the strap links (1, View A) from the stored position
on the end of the insert (3) and rotate the links down as
shown.
3. Assemble the brackets (4, View B) to the top connectors
(5) on the boom insert (6):
a. Remove the pin (4a).
b. Loosen the nuts on the cap screws (4b).
c. Slip the brackets (4) over the top connectors (5).
d. Align the connecting holes in the brackets with
those in the connectors.
e. Securely tighten the nuts on the cap screws (4b) so

mounting lugs.

the boom straps (10) with the special strap pins (11).
The pin heads must face out.
