BOOM LADDERS
See Figure 4-62
If equipped, optional boom ladders are stored inside the
19.7 ft (6 m) boom insert with sheaves.
The ladders are designed for use in assembly, disassembly,
and maintenance of the #74A boom sections and
components.
Each ladder weighs approximately 27 lb (12 kg).
Installing the Ladders
Use two people to remove the ladders from the insert: one
person inside the insert to unlatch and lift the ladders and
another person outside of the insert to help guide the ladders
out of the insert.
Perform the following steps for both ladders:
1. The boom sections must be blocked in the horizontal
position.
2. Unhook the rubber latches (4, View B).
3. Lift the ladder (1) up and out of the hooks (2, View A).
4. Guide the ladder through the lacings to the outside of the
insert.
5. Place the ladder in the desired outside location on the
insert (View C).
• The ladder must be securely hooked over the
inboard side of the upper chord and must rest firmly
against the lower chord.
• The ladder must hang vertically against the insert
when in use.
Storing the Ladders
Use two people to store the ladders in the insert: one person
outside of the insert to help guide the ladders into the insert,
and another person inside the insert to lift the ladders and
latch them in position.
Perform the following steps for both ladders:
1. Lift the ladder (1) through the lacings to the inside of the
insert.
2. Hang the ladder rails over the hooks (2, View A) inside
the insert.
3. Route the rubber latches (4, View B) tightly over the
lower rail and connect them to bracket (3).
4. Make sure the ladder cannot move once it is latched in
place.

• Make sure the boom ladders are properly secured to
the boom inserts.
• When climbing a ladder, your hands must be free of
any objects. Objects which cannot be carried in
pockets or tool belts must be lifted into place onto the
