Connect Mast Straps

See Figure 4-29
Mast straps and links are shipped in the stored position on
the fixed mast top and inserts as shown in View B. Connect
straps as follows:
1. Remove all shipping pins (26, View B) and store them in
tubes (27, View C) or brackets (28).
2. Attach links (29, View B) to straps (30, View C) with pins
(31).
NOTE If your crane is prepared for a MAX-ER
Attachment, the MAX-ER counterweight straps are
stored in the outboard strap brackets on the mast
top and inserts.
The counterweight straps do not have to be
removed from the mast sections when operating
without a MAX-ER attachment. Counterweight
straps must, however, be unpinned from strap
brackets and pinned together in working
position before raising mast (like mast straps in
View C).
To prevent counterweight straps from flopping
around during operation, securely attach them to
the mast straps.

Connect Live Mast Straps to Fixed Mast Straps

See Figure 4-29
1. Lower live mast (32, View G) until adjustable links (33,
View F1 or F2) are just above ends of straps (30) on
insert.
2. For 100 ft (30,5 m) mast, remove retaining pins (34,
View F1) and rotate adjustable links (33) so long end is
down. Store retaining pins in links (33).
For 140 ft (42,7 m) mast, leave long end of adjustable
links (33) pinned to mast straps (View F2).
3. Lower live mast as required to align connecting holes
and pin adjustable links (33) to straps (30) with pins (31).
