Ladder Safety Information
Pivoting Ladder Falling Hazard
:
Make sure horizontal pin at right pivot is fully engaged when
ladder is in the down position. If the ladder is not pinned in the
down position, the top step can pivot inward and down when
stepped on. This can cause a fall resulting in death or serious
injury. Always check the horizontal capture pin if you did not
personally set it just before use. Always use the hand rails.
Always face the drill when on the ladder.
Avoid equipment damage. Make sure vertical pin at right pivot
is fully engaged when ladder is raised to storage position.
Ladder must be securely stored for transport.
Ladder use is easiest and least obstructed when drill
wings are folded (page 34). Ladder may be lowered,
used and raised with wings unfolded, as shown at
right, but lowest ladder step may strike lowered
openers, and will strike raised openers. The lowest
step is mounted with rubber straps to prevent serious
damage to openers.
Ladder General Information
The ladder on the left side of the mainframe provides
access to the walkboard for material loading and routine
lid/hopper maintenance. This ladder pivots diagonally,
and is held in position by one of two spring-loaded pins.
Deploying Ladder
1.
Fold the wings for easiest ladder use. See page 34.
2.
Use one hand to hold the ladder up, while pulling
vertical pin
down.
3.
Carefully swing ladder forward and down, until you
hear and see the horizontal pin
seat itself with the
ladder down. If an opener is in the way, it may be
necessary to push on the ladder to achieve lock.
Using Ladder
1.
Pull outward on the ladder to check that the
horizontal pivot pin
is holding it.
2.
Ascend and descend the ladder while facing the drill.
3.
Use the handrails when on the higher steps.
Storing Ladder
1.
Pull the horizontal pivot pin
to the rear.

While holding the pin out, carefully swing the ladder
up and to the rear, until you hear and see the vertical
