LADDER INSTALLATION (PAST)
The past production folding ladder shown in Figure 3-11
cannot be used with the VPC-MAX attachment.
The folding ladder provides access to the rotating bed for
servicing the crane.
The ladder weights 18 kg (40 lb).
See Figure 3-11
for following procedures.
Installing Ladder
If the ladder has been removed, install it as follows:
1. Lower the bottom ladder (3) to the standalone position
as shown in View C. Install the quick-release pins (5) in
the upper holes B.
The pins must be in the upper holes B so the ladder
cannot fold during installation.
2. Hook the ladder to the pins in the left-rear platform (1)
with the hooks (4) on the end of the ladder.
3. Remove the three pins (5, View E).
4. Lower the ladder support bracket (6, View D) and pin it
to the top ladder (2) with two quick-release pins (5).
5. Pin the ladder support bracket (6, View D) to the rotating
bed lug (7) with the remaining quick-release pin (5).
6. Install the padlock (8).
Storing Ladder
The ladder must be stored (or removed) before operating the
crane or damage will occur.
1. Remove the quick-release pins (5, View B or C) and
rotate the bottom ladder (3) up.
2. Pin the bottom ladder (3, View A) to the top ladder (2)
with the quick-release pins (5).
Using Ladder (Working Position)
1. If the ladder has been removed, install it as instructed
earlier.
2. If the ladder is stored, remove quick-release pins (5,
View A) and rotate the bottom ladder (3) down.
3. Install the quick-release pins (5, View B) in the lower
holes A.
The pins must be in the lower holes A so the ladder folds
if the crane counterweights are accidentally extended.
Otherwise, the ladder will be damaged.
Removing Ladder
1. Lower the bottom ladder (3) to the standalone position
as shown in View C. Install the quick-release pins (5) in
the upper holes B.
The pins must be in the upper holes B so the ladder
cannot fold during removal.
2. Remove the padlock (8).
3. Unpin the ladder support bracket (6, View D) from the
rotating bed lug (7) by removing one quick-release pin
(5).
4. Remove the other two quick-release pins (5, View D).
5. Rotate the ladder support bracket (6, View E) up and
install three quick-release pins (5).
6. Attach the padlock (8, View D) to the rotating bed lug (7).
7. Unhook the ladder hooks (4) from the pins in the left-rear
platform (1) and lift the ladder away from the rotating
bed.
